Change history for coverage.py
==============================
These changes are listed in decreasing version number order. Note this can be
different from a strict chronological order when there are two branches in
development at the same time, such as 4.5.x and 5.0.
See :ref:`migrating` for significant changes that might be required when
upgrading your version of coverage.py.
.. When updating the "Unreleased" header to a specific version, use this
.. format. Don't forget the jump target:
..
.. .. _changes_9-8-1:
..
.. Version 9.8.1 โ 2027-07-27
.. --------------------------
.. start-releases
.. _changes_7-11-1:
Version 7.11.1 โ 2025-11-07
---------------------------
- Fix: if the measurement core defaults to "sysmon" (the default for Python
3.14+ since v7.9.1), but sysmon can't support some aspect of your
configuration (concurrency settings, dynamic contexts, and so on), then the
ctrace core is used instead. Previously, this would result in an error.
Now a warning is issued instead, explaining the fallback. An explicit request
for sysmon with conflicting settings will still result in an error. Closes
`issue 2064`_.
- Fix: some multi-line case clauses or for loops (and probably other
constructs) could cause incorrect claims of missing branches with the
sys.monitoring core, as described in `issue 2070`_. This is now fixed.
- Fix: when running in pytest under coverage, a ``breakpoint()`` would stop in
the wrong frame, one level down from where it should, as described in `issue
1420`_. This was due to a coverage change in v6.4.1 that seemed to give a
slight performance improvement, but I couldn't reproduce the performance
gain, so it's been reverted, fixing the debugger problem.
- A new debug option ``--debug=core`` shows which core is in use and why.
- Split ``sqlite`` debugging information out of the ``sys`` :ref:`coverage
debug ` and :ref:`cmd_run_debug` options since it's bulky and not
very useful.
- Updated the :ref:`howitworks` page to better describe the three different
measurement cores.

.. _changes_7-11-0:
Version 7.11.0 โ 2025-10-15
---------------------------
- Dropped support for Python 3.9, declared support for Python 3.15 alpha.
.. _changes_7-10-7:
Version 7.10.7 โ 2025-09-21
---------------------------
- Performance: with branch coverage in large files, generating HTML, JSON, or
LCOV reports could take far too long due to some quadratic behavior when
creating the function and class index pages. This is now fixed, closing
`issue 2048`_. Thanks to Daniel Diniz for help diagnosing the problem.
- Most warnings and a few errors now have links to a page in the docs
explaining the specific message. Closes `issue 1921`_.
.. _issue 1921: https://github.com/nedbat/coveragepy/issues/1921
.. _issue 2048: https://github.com/nedbat/coveragepy/issues/2048
.. _changes_7-10-6:
Version 7.10.6 โ 2025-08-29
---------------------------
- Fix: ``source`` directories were not properly communicated to subprocesses
that ran in different directories, as reported in `issue 1499`_. This is now
fixed.
- Performance: `Alex Gaynor continues fine-tuning `_ the speed of
combination, especially with many contexts.
.. _issue 1499: https://github.com/nedbat/coveragepy/issues/1499
.. _pull 2038: https://github.com/nedbat/coveragepy/pull/2038
.. _changes_7-10-5:
Version 7.10.5 โ 2025-08-23
---------------------------
- Big speed improvements for ``coverage combine``: it's now about twice as
fast! Huge thanks to Alex Gaynor for pull requests `2032 `_,
`2033 `_, and `2034 `_.
.. _pull 2032: https://github.com/nedbat/coveragepy/pull/2032
.. _pull 2033: https://github.com/nedbat/coveragepy/pull/2033
.. _pull 2034: https://github.com/nedbat/coveragepy/pull/2034
.. _changes_7-10-4:
Version 7.10.4 โ 2025-08-16
---------------------------
- Added ``patch = fork`` for times when the built-in forking support is
insufficient.
- Fix: ``patch = execv`` also inherits the entire coverage configuration now.
.. _changes_7-10-3:
Version 7.10.3 โ 2025-08-10
---------------------------
- Fixes for ``patch = subprocess``:
- If subprocesses spawned yet more subprocesses simultaneously, some coverage
could be missed. This is now fixed, closing `issue 2024`_.
- If subprocesses were created in other directories, their data files were
stranded there and not combined into the totals, as described in `issue
2025`_. This is now fixed.
- On Windows (or maybe only some Windows?) the patch would fail with a
``ModuleNotFound`` error trying to import coverage. This is now fixed,
closing `issue 2022`_.
- Originally only options set in the coverage configuration file would apply
to subprocesses. Options set on the ``coverage run`` command line (such as
``--branch``) wouldn't be communicated to the subprocesses. This could
lead to combining failures, as described in `issue 2021`_. Now the entire
configuration is used in subprocesses, regardless of its origin.
- Added ``debug=patch`` to help diagnose problems.
- Fix: really close all SQLite databases, even in-memory ones. Closes `issue
2017`_.

.. _changes_7-10-2:
Version 7.10.2 โ 2025-08-03
---------------------------
- Fix: some code with NOP bytecodes could report missing branches that are
actually executed. This is now fixed, closing `issue 1999`_. Python 3.9
still shows the problem.
.. _issue 1999: https://github.com/nedbat/coveragepy/issues/1999

- Fix: the exclusion for ``if TYPE_CHECKING:`` was wrong: it marked the branch
as partial, but it should have been a line exclusion so the entire clause
would be excluded. Improves `issue 831`_.
- Fix: changed where .pth files are written for ``patch = subprocess``, closing
`issue 2006`_.

Version 7.10.0 โ 2025-07-24
---------------------------
- A new configuration option: ":ref:`config_run_patch`" specifies named patches
to work around some limitations in coverage measurement. These patches are
available:
- ``patch = _exit`` lets coverage save its data even when :func:`os._exit()
` is used to abruptly end the process. This closes
long-standing `issue 310`_ as well as its duplicates: `issue 312`_, `issue
1673`_, `issue 1845`_, and `issue 1941`_.
- ``patch = subprocess`` measures coverage in Python subprocesses created
with :mod:`subprocess`, :func:`os.system`, or one of the :func:`execv
` or :func:`spawnv ` family of
functions. Closes old `issue 367`_, its duplicate `issue 378`_ and old
`issue 689`_.
- ``patch = execv`` adjusts the :func:`execv ` family of
functions to save coverage data before ending the current program and
starting the next. Not available on Windows. Closes `issue 43`_ after 15
years!
- The HTML report now dimly colors subsequent lines in multi-line statements.
They used to have no color. This gives a better indication of the amount of
code missing in the report. Closes `issue 1308`_.
- Two new exclusion patterns are part of the defaults: ``...`` is automatically
excluded as a line and ``if TYPE_CHECKING:`` is excluded as a branch. Closes
`issue 831`_.
- A new command-line option: ``--save-signal=USR1`` specifies a signal that
coverage.py will listen for. When the signal is sent, the coverage data will
be saved. This makes it possible to save data from within long-running
processes. Thanks, `Arkady Gilinsky `_.
- A new configuration option: ":ref:`config_report_partial_also`" is a list of
regexes to add as pragmas for partial branches. This parallels the
":ref:`config_report_exclude_also`" setting for adding line exclusion
patterns.
- A few file path configuration settings didn't allow for tilde expansion:
:ref:`config_json_output`, :ref:`config_lcov_output` and
:ref:`config_run_debug_file`. This is now fixed.
- Wheels are included for 3.14 now that 3.14 rc1 is available.
- We no longer ship a PyPy-specific wheel. PyPy will install the pure-Python
wheel. Closes `issue 2001`_.
- In the very unusual situation of not having a current frame, coverage no
longer crashes when using the sysmon core, fixing `issue 2005`_.

Version 7.9.2 โ 2025-07-03
--------------------------
- Fix: complex conditionals within a line might cause a KeyError when using
sys.monitoring, as reported in `issue 1991`_. This is now fixed.
- Fix: we can now measure coverage for code in Python archive (.par) files.
Thanks, `Itamer Oren `_.

Version 7.9.1 โ 2025-06-13
--------------------------
- The "no-ctracer" warning is not issued for Python pre-release versions.
Coverage doesn't ship compiled wheels for those versions, so this was far too
noisy.
- On Python 3.14+, the "sysmon" core is now the default if it's supported for
your configuration. Plugins and dynamic contexts are still not supported
with it.
.. _changes_7-9-0:
Version 7.9.0 โ 2025-06-11
--------------------------
- Added a ``[run] core`` configuration setting to specify the measurement core,
which was previously only available through the COVERAGE_CORE environment
variable. Finishes `issue 1746`_.
- Fixed incorrect rendering of f-strings with doubled braces, closing `issue
1980`_.
- If the C tracer core can't be imported, a warning ("no-ctracer") is issued
with the reason.
- The C tracer core extension module now conforms to `PEP 489`_, closing `issue
1977`_. Thanks, `Adam Turner `_.
- Fixed a "ValueError: min() arg is an empty sequence" error caused by strange
empty modules, found by `oss-fuzz`_.

PYTHONWARNDEFAULTENCODING, fixing `issue 1966`_. Thanks, `Henry Schreiner
`_.
- Fixed a race condition when using sys.monitoring with free-threading Python,
closing `issue 1970`_.

Version 7.8.0 โ 2025-03-30
--------------------------
- Added a new ``source_dirs`` setting for symmetry with the existing
``source_pkgs`` setting. It's preferable to the existing ``source`` setting,
because you'll get a clear error when directories don't exist. Fixes `issue
1942`_. Thanks, `Jeremy Fleischman `_.
- Fix: the PYTHONSAFEPATH environment variable new in Python 3.11 is properly
supported, closing `issue 1696`_. Thanks, `Philipp A. `_. This
works properly except for a detail when using the ``coverage`` command on
Windows. There you can use ``python -m coverage`` instead if you need exact
emulation.

Version 7.7.1 โ 2025-03-21
--------------------------
- A few small tweaks to the sys.monitoring support for Python 3.14. Please
test!
.. _changes_7-7-0:
Version 7.7.0 โ 2025-03-16
--------------------------
- The Coverage object has a new method, :meth:`.Coverage.branch_stats` for
getting simple branch information for a module. Closes `issue 1888`_.
- The :class:`Coverage constructor<.Coverage>` now has a ``plugins`` parameter
for passing in plugin objects directly, thanks to `Alex Gaynor `_.
- Many constant tests in if statements are now recognized as being optimized
away. For example, previously ``if 13:`` would have been considered a branch
with one path not taken. Now it is understood as always true and no coverage
is missing.
- The experimental sys.monitoring support now works for branch coverage if you
are using Python 3.14.0 alpha 6 or newer. This should reduce the overhead
coverage.py imposes on your test suite. Set the environment variable
``COVERAGE_CORE=sysmon`` to try it out.
- Confirmed support for PyPy 3.11. Thanks Michaล Gรณrny.

building reliably.

Version 7.6.11 โ 2025-02-08
---------------------------
- Fix: a memory leak in CTracer has been fixed. The details are in `issue
1924`_ and `pytest-dev 676`_. This should reduce the memory footprint for
everyone even if it hadn't caused a problem before.
- We now ship a py3-none-any.whl wheel file. Thanks, `Russell Keith-Magee

Version 7.6.10 โ 2024-12-26
---------------------------
- Fix: some descriptions of missing branches in HTML and LCOV reports were
incorrect when multi-line statements were involved (`issue 1874`_ and `issue
1875`_). These are now fixed.
- Fix: Python 3.14 `defers evaluation of annotations `_ by moving them
into separate code objects. That code is rarely executed, so coverage.py
would mark them as missing, as reported in `issue 1908`_. Now they are
ignored by coverage automatically.
- Fixed an obscure and mysterious problem on PyPy 3.10 seemingly involving
mocks, imports, and trace functions: `issue 1902`_. To be honest, I don't
understand the problem or the solution, but ``git bisect`` helped find it,
and now it's fixed.
- Docs: re-wrote the :ref:`subprocess` page to put multiprocessing first and to
highlight the correct use of :class:`multiprocessing.Pool
`.

- Fix: `Tomas Uribe fixed `_ a performance problem in the XML
report. Large code bases should produce XML reports much faster now.
.. _pull 1901: https://github.com/nedbat/coveragepy/pull/1901
.. _changes_7-6-8:
Version 7.6.8 โ 2024-11-23
--------------------------
- Fix: the LCOV report code assumed that a branch line that took no branches
meant that the entire line was unexecuted. This isn't true in a few cases:
the line might always raise an exception, or might have been optimized away.
Fixes `issue 1896`_.
- Fix: similarly, the HTML report will now explain that a line that jumps to
none of its expected destinations must have always raised an exception.
Previously, it would say something nonsensical like, "line 4 didn't jump to
line 5 because line 4 was never true, and it didn't jump to line 7 because
line 4 was always true." This was also shown in `issue 1896`_.

- Fix: ugh, the other assert from 7.6.5 can also be encountered in the wild,
so it's been restored to a conditional. Sorry for the churn.
.. _changes_7-6-6:
Version 7.6.6 โ 2024-11-15

- One of the new asserts from 7.6.5 caused problems in real projects, as
reported in `issue 1891`_. The assert has been removed.

Version 7.6.5 โ 2024-11-14
--------------------------
- Fix: fine-tuned the exact Python version (3.12.6) when exiting from ``with``
statements changed how they traced. This affected whether people saw the
fix for `issue 1880`_.
- Fix: isolate our code more from mocking in the os module that in rare cases
can cause `bizarre behavior `_.
- Refactor: some code unreachable code paths in parser.py were changed to
asserts. If you encounter any of these, please let me know!

Version 7.6.3 โ 2024-10-13
--------------------------
- Fix: nested context managers could incorrectly be analyzed to flag a missing
branch on the last context manager, as described in `issue 1876`_. This is
now fixed.
- Fix: the missing branch message about not exiting a module had an extra
"didn't," as described in `issue 1873`_. This is now fixed.

Version 7.6.2 โ 2024-10-09
--------------------------
- Dropped support for Python 3.8 and PyPy 3.8.
- Fix: a final wildcard match/case clause assigning to a name (``case _ as
value``) was incorrectly marked as a missing branch. This is now fixed,
closing `issue 1860`_.
- Fewer things are considered branches now. Lambdas, comprehensions, and
generator expressions are no longer marked as missing branches if they don't
complete execution. Closes `issue 1852`_.
- Fix: the HTML report didn't properly show multi-line f-strings that end with
a backslash continuation. This is now fixed, closing `issue 1836`_, thanks
to `LiuYinCarl and Marco Ricci `_.
- Fix: the LCOV report now has correct line numbers (fixing `issue 1846`_) and
better branch descriptions for BRDA records (fixing `issue 1850`_). There
are other changes to lcov also, including a new configuration option
:ref:`line_checksums ` to control whether line
checksums are included in the lcov report. The default is false. To keep
checksums set it to true. All this work is thanks to Zack Weinberg
(`pull 1849`_ and `pull 1851`_).
- Fixed the docs for multi-line regex exclusions, closing `issue 1863`_.
- Fixed a potential crash in the C tracer, closing `issue 1835`_, thanks to

This is now fixed, thanks to `Ask Hjorth Larsen `_.
- Fix: backslashes preceding a multi-line backslashed string could confuse the
HTML report. This is now fixed, thanks to `LiuYinCarl `_.

Version 7.6.0 โ 2024-07-11
--------------------------
- Exclusion patterns can now be multi-line, thanks to `Daniel Diniz `_. This enables many interesting exclusion use-cases, including those
requested in issues `118 `_ (entire files), `996
`_ (multiple lines only when appearing together), `1741
`_ (remainder of a function), and `1803 `_
(arbitrary sequence of marked lines). See the :ref:`multi_line_exclude`
section of the docs for more details and examples.
- The JSON report now includes per-function and per-class coverage information.
Thanks to `Daniel Diniz `_ for getting the work started. This
closes `issue 1793`_ and `issue 1532`_.
- Fixed an incorrect calculation of "(no class)" lines in the HTML classes
report.
- Python 3.13.0b3 is supported.

Version 7.5.4 โ 2024-06-22
--------------------------
- If you attempt to combine statement coverage data with branch coverage data,
coverage.py used to fail with the message "Can't combine arc data with line
data" or its reverse, "Can't combine line data with arc data." These
messages used internal terminology, making it hard for people to understand
the problem. They are now changed to mention "branch coverage data" and
"statement coverage data."
- Fixed a minor branch coverage problem with wildcard match/case cases using
names or guard clauses.
- Started testing on 3.13 free-threading (nogil) builds of Python. I'm not
claiming full support yet. Closes `issue 1799`_.

Version 7.5.3 โ 2024-05-28
--------------------------
- Performance improvements for combining data files, especially when measuring
line coverage. A few different quadratic behaviors were eliminated. In one
extreme case of combining 700+ data files, the time dropped from more than
three hours to seven minutes. Thanks for Kraken Tech for funding the fix.
- Performance improvements for generating HTML reports, with a side benefit of
reducing memory use, closing `issue 1791`_. Thanks to Daniel Diniz for
helping to diagnose the problem.

.. _changes_7-5-2:
Version 7.5.2 โ 2024-05-24
--------------------------
- Fix: nested matches of exclude patterns could exclude too much code, as
reported in `issue 1779`_. This is now fixed.
- Changed: previously, coverage.py would consider a module docstring to be an
executable statement if it appeared after line 1 in the file, but not
executable if it was the first line. Now module docstrings are never counted
as executable statements. This can change coverage.py's count of the number
of statements in a file, which can slightly change the coverage percentage
reported.
- In the HTML report, the filter term and "hide covered" checkbox settings are
remembered between viewings, thanks to `Daniel Diniz `_.
- Python 3.13.0b1 is supported.
- Fix: parsing error handling is improved to ensure bizarre source files are
handled gracefully, and to unblock oss-fuzz fuzzing, thanks to `Liam DeVoe
`_. Closes `issue 1787`_.

Version 7.5.1 โ 2024-05-04
--------------------------
- Fix: a pragma comment on the continuation lines of a multi-line statement
now excludes the statement and its body, the same as if the pragma is
on the first line. This closes `issue 754`_. The fix was contributed by
`Daniel Diniz `_.
- Fix: very complex source files like `this one `_ could
cause a maximum recursion error when creating an HTML report. This is now
fixed, closing `issue 1774`_.
- HTML report improvements:
- Support files (JavaScript and CSS) referenced by the HTML report now have
hashes added to their names to ensure updated files are used instead of
stale cached copies.
- Missing branch coverage explanations that said "the condition was never
false" now read "the condition was always true" because it's easier to
understand.
- Column sort order is remembered better as you move between the index pages,
fixing `issue 1766`_. Thanks, `Daniel Diniz `_.

--------------------------
- Added initial support for function and class reporting in the HTML report.
There are now three index pages which link to each other: files, functions,
and classes. Other reports don't yet have this information, but it will be
added in the future where it makes sense. Feedback gladly accepted!
Finishes `issue 780`_.
- Other HTML report improvements:
- There is now a "hide covered" checkbox to filter out 100% files, finishing
`issue 1384`_.
- The index page is always sorted by one of its columns, with clearer
indications of the sorting.
- The "previous file" shortcut key didn't work on the index page, but now it
does, fixing `issue 1765`_.
- The debug output showing which configuration files were tried now shows
absolute paths to help diagnose problems where settings aren't taking effect,
and is renamed from "attempted_config_files" to the more logical
"config_files_attempted."
- Python 3.13.0a6 is supported.

Version 7.4.4 โ 2024-03-14
--------------------------
- Fix: in some cases, even with ``[run] relative_files=True``, a data file
could be created with absolute path names. When combined with other relative
data files, it was random whether the absolute file names would be made
relative or not. If they weren't, then a file would be listed twice in
reports, as detailed in `issue 1752`_. This is now fixed: absolute file
names are always made relative when combining. Thanks to Bruno Rodrigues dos
Santos for support.
- Fix: the last case of a match/case statement had an incorrect message if the
branch was missed. It said the pattern never matched, when actually the
branch is missed if the last case always matched.
- Fix: clicking a line number in the HTML report now positions more accurately.
- Fix: the ``report:format`` setting was defined as a boolean, but should be a
string. Thanks, `Tanaydin Sirin `_. It is also now documented
on the :ref:`configuration page `.

Version 7.4.2 โ 2024-02-20
--------------------------
- Fix: setting ``COVERAGE_CORE=sysmon`` no longer errors on 3.11 and lower,
thanks `Hugo van Kemenade `_. It now issues a warning that
sys.monitoring is not available and falls back to the default core instead.

Version 7.4.1 โ 2024-01-26
--------------------------
- Python 3.13.0a3 is supported.
- Fix: the JSON report now includes an explicit format version number, closing
`issue 1732`_.

Version 7.4.0 โ 2023-12-27
--------------------------
- In Python 3.12 and above, you can try an experimental core based on the new
:mod:`sys.monitoring ` module by defining a
``COVERAGE_CORE=sysmon`` environment variable. This should be faster for
line coverage, but not for branch coverage, and plugins and dynamic contexts
are not yet supported with it. I am very interested to hear how it works (or
doesn't!) for you.

Version 7.3.4 โ 2023-12-20
--------------------------
- Fix: the change for multi-line signature exclusions in 7.3.3 broke other
forms of nested clauses being excluded properly. This is now fixed, closing
`issue 1713`_.
- Fix: in the HTML report, selecting code for copying won't select the line
numbers also. Thanks, `Robert Harris `_.

--------------------------
- Fix: function definitions with multi-line signatures can now be excluded by
matching any of the lines, closing `issue 684`_. Thanks, `Jan Rusak,
Maciej Kowalczyk and Joanna Ejzel `_.
- Fix: XML reports could fail with a TypeError if files had numeric components
that were duplicates except for leading zeroes, like ``file1.py`` and
``file001.py``. Fixes `issue 1709`_.
- The ``coverage annotate`` command used to announce that it would be removed
in a future version. Enough people got in touch to say that they use it, so
it will stay. Don't expect it to keep up with other new features though.
- Added new :ref:`debug options `:
- ``pytest`` writes the pytest test name into the debug output.
- ``dataop2`` writes the full data being added to CoverageData objects.

Version 7.3.2 โ 2023-10-02
--------------------------
- The ``coverage lcov`` command ignored the ``[report] exclude_lines`` and
``[report] exclude_also`` settings (`issue 1684`_). This is now fixed,
thanks `Jacqueline Lee `_.
- Sometimes SQLite will create journal files alongside the coverage.py database
files. These are ephemeral, but could be mistakenly included when combining
data files. Now they are always ignored, fixing `issue 1605`_. Thanks to
Brad Smith for suggesting fixes and providing detailed debugging.
- On Python 3.12+, we now disable SQLite writing journal files, which should be
a little faster.
- The new 3.12 soft keyword ``type`` is properly bolded in HTML reports.
- Removed the "fullcoverage" feature used by CPython to measure the coverage of
early-imported standard library modules. CPython `stopped using it
<88054_>`_ in 2021, and it stopped working completely in Python 3.13.

Version 7.3.1 โ 2023-09-06
--------------------------
- The semantics of stars in file patterns has been clarified in the docs. A
leading or trailing star matches any number of path components, like a double
star would. This is different than the behavior of a star in the middle of a
pattern. This discrepancy was `identified by Sviatoslav Sydorenko
`_, who `provided patient detailed diagnosis `_ and
graciously agreed to a pragmatic resolution.
- The API docs were missing from the last version. They are now `restored
`_.

--------------------------
- Added a :meth:`.Coverage.collect` context manager to start and stop coverage
data collection.
- Dropped support for Python 3.7.
- Fix: in unusual circumstances, SQLite cannot be set to asynchronous mode.
Coverage.py would fail with the error ``Safety level may not be changed
inside a transaction.`` This is now avoided, closing `issue 1646`_. Thanks
to Michael Bell for the detailed bug report.
- Docs: examples of configuration files now include separate examples for the
different syntaxes: .coveragerc, pyproject.toml, setup.cfg, and tox.ini.
- Fix: added ``nosemgrep`` comments to our JavaScript code so that
semgrep-based SAST security checks won't raise false alarms about security
problems that aren't problems.
- Added a CITATION.cff file, thanks to `Ken Schackart `_.

- Fix: reverted a `change from 6.4.3 `_ that helped Cython, but
also increased the size of data files when using dynamic contexts, as
described in the now-fixed `issue 1586`_. The problem is now avoided due to a
recent change (`issue 1538 `_). Thanks to `Anders Kaseorg
`_ and David Szotten for persisting with problem reports and
detailed diagnoses.

--------------------------
- Fix: the ``lcov`` command could raise an IndexError exception if a file is
translated to Python but then executed under its own name. Jinja2 does this
when rendering templates. Fixes `issue 1553`_.
- Python 3.12 beta 1 now inlines comprehensions. Previously they were compiled
as invisible functions and coverage.py would warn you if they weren't
completely executed. This no longer happens under Python 3.12.
- Fix: the ``coverage debug sys`` command includes some environment variables
in its output. This could have included sensitive data. Those values are
now hidden with asterisks, closing `issue 1628`_.

fixed.
.. _changes_7-2-4:
Version 7.2.4 โ 2023-04-28
--------------------------
PyCon 2023 sprint fixes!
- Fix: with ``relative_files = true``, specifying a specific file to include or
omit wouldn't work correctly (`issue 1604`_). This is now fixed, with
testing help by `Marc Gibbons `_.
- Fix: the XML report would have an incorrect ```` element when using
relative files and the source option ended with a slash (`issue 1541`_).
This is now fixed, thanks to `Kevin Brown-Silva `_.
- When the HTML report location is printed to the terminal, it's now a
terminal-compatible URL, so that you can click the location to open the HTML
file in your browser. Finishes `issue 1523`_ thanks to `Ricardo Newbery
`_.
- Docs: a new :ref:`Migrating page ` with details about how to
migrate between major versions of coverage.py. It currently covers the
wildcard changes in 7.x. Thanks, `Brian Grohe `_.

- Fix: the :ref:`config_run_sigterm` setting was meant to capture data if a
process was terminated with a SIGTERM signal, but it didn't always. This was
fixed thanks to `Lewis Gaul `_, closing `issue 1599`_.
- Performance: HTML reports with context information are now much more compact.
File sizes are typically as small as one-third the previous size, but can be
dramatically smaller. This closes `issue 1584`_ thanks to `Oleh Krehel

- Fix: if a virtualenv was created inside a source directory, and a sourced
package was installed inside the virtualenv, then all of the third-party
packages inside the virtualenv would be measured. This was incorrect, but
has now been fixed: only the specified packages will be measured, thanks to
`Manuel Jacob `_.
- Fix: the ``coverage lcov`` command could create a .lcov file with incorrect
LF (lines found) and LH (lines hit) totals. This is now fixed, thanks to
`Ian Moore `_.

duplicate ```` elements. This is now fixed, thanks to `Benjamin

--------------------------
- Added a new setting ``[report] exclude_also`` to let you add more exclusions
without overwriting the defaults. Thanks, `Alpha Chen `_,
closing `issue 1391`_.
- Added a :meth:`.CoverageData.purge_files` method to remove recorded data for
a particular file. Contributed by `Stephan Deibel `_.
- Fix: when reporting commands fail, they will no longer congratulate
themselves with messages like "Wrote XML report to file.xml" before spewing a
traceback about their failure.
- Fix: arguments in the public API that name file paths now accept pathlib.Path
objects. This includes the ``data_file`` and ``config_file`` arguments to
the Coverage constructor and the ``basename`` argument to CoverageData.
Closes `issue 1552`_.
- Fix: In some embedded environments, an IndexError could occur on stop() when
the originating thread exits before completion. This is now fixed, thanks to
`Russell Keith-Magee `_, closing `issue 1542`_.
- Added a ``py.typed`` file to announce our type-hintedness. Thanks,

- Performance: fixed a slowdown with dynamic contexts that's been around since
6.4.3. The fix closes `issue 1538`_. Thankfully this doesn't break the

Version 7.0.3 โ 2023-01-03
--------------------------
- Fix: when using pytest-cov or pytest-xdist, or perhaps both, the combining
step could fail with ``assert row is not None`` using 7.0.2. This was due to
a race condition that has always been possible and is still possible. In
7.0.1 and before, the error was silently swallowed by the combining code.
Now it will produce a message "Couldn't combine data file" and ignore the
data file as it used to do before 7.0.2. Closes `issue 1522`_.

Version 7.0.2 โ 2023-01-02
--------------------------
- Fix: when using the ``[run] relative_files = True`` setting, a relative
``[paths]`` pattern was still being made absolute. This is now fixed,
closing `issue 1519`_.
- Fix: if Python doesn't provide tomllib, then TOML configuration files can
only be read if coverage.py is installed with the ``[toml]`` extra.
Coverage.py will raise an error if TOML support is not installed when it sees
your settings are in a .toml file. But it didn't understand that
``[tools.coverage]`` was a valid section header, so the error wasn't reported
if you used that header, and settings were silently ignored. This is now
fixed, closing `issue 1516`_.
- Fix: adjusted how decorators are traced on PyPy 7.3.10, fixing `issue 1515`_.
- Fix: the ``coverage lcov`` report did not properly implement the
``--fail-under=MIN`` option. This has been fixed.
- Refactor: added many type annotations, including a number of refactorings.
This should not affect outward behavior, but they were a bit invasive in some
places, so keep your eyes peeled for oddities.
- Refactor: removed the vestigial and long untested support for Jython and
IronPython.

- When checking if a file mapping resolved to a file that exists, we weren't
considering files in .whl files. This is now fixed, closing `issue 1511`_.
- File pattern rules were too strict, forbidding plus signs and curly braces in
directory and file names. This is now fixed, closing `issue 1513`_.
- Unusual Unicode or control characters in source files could prevent
reporting. This is now fixed, closing `issue 1512`_.

Version 7.0.0b1 โ 2022-12-03
----------------------------
A number of changes have been made to file path handling, including pattern
matching and path remapping with the ``[paths]`` setting (see
:ref:`config_paths`). These changes might affect you, and require you to
update your settings.
(This release includes the changes from `6.6.0b1`__, since 6.6.0 was never
released.)
__ https://coverage.readthedocs.io/en/latest/changes.html#changes-6-6-0b1
- Changes to file pattern matching, which might require updating your
configuration:
- Previously, ``*`` would incorrectly match directory separators, making
precise matching difficult. This is now fixed, closing `issue 1407`_.
- Now ``**`` matches any number of nested directories, including none.
- Improvements to combining data files when using the
:ref:`config_run_relative_files` setting, which might require updating your
configuration:
- During ``coverage combine``, relative file paths are implicitly combined
without needing a ``[paths]`` configuration setting. This also fixed
`issue 991`_.
- A ``[paths]`` setting like ``*/foo`` will now match ``foo/bar.py`` so that
relative file paths can be combined more easily.
- The :ref:`config_run_relative_files` setting is properly interpreted in
more places, fixing `issue 1280`_.
- When remapping file paths with ``[paths]``, a path will be remapped only if
the resulting path exists. The documentation has long said the prefix had to
exist, but it was never enforced. This fixes `issue 608`_, improves `issue
649`_, and closes `issue 757`_.
- Reporting operations now implicitly use the ``[paths]`` setting to remap file
paths within a single data file. Combining multiple files still requires the
``coverage combine`` step, but this simplifies some single-file situations.
Closes `issue 1212`_ and `issue 713`_.
- The ``coverage report`` command now has a ``--format=`` option. The original
style is now ``--format=text``, and is the default.
- Using ``--format=markdown`` will write the table in Markdown format, thanks
to `Steve Oswald `_, closing `issue 1418`_.
- Using ``--format=total`` will write a single total number to the
output. This can be useful for making badges or writing status updates.
- Combining data files with ``coverage combine`` now hashes the data files to
skip files that add no new information. This can reduce the time needed.
Many details affect the speed-up, but for coverage.py's own test suite,
combining is about 40% faster. Closes `issue 1483`_.
- When searching for completely un-executed files, coverage.py uses the
presence of ``__init__.py`` files to determine which directories have source
that could have been imported. However, `implicit namespace packages`_ don't
require ``__init__.py``. A new setting ``[report]
include_namespace_packages`` tells coverage.py to consider these directories
during reporting. Thanks to `Felix Horvat `_ for the
contribution. Closes `issue 1383`_ and `issue 1024`_.
- Fixed environment variable expansion in pyproject.toml files. It was overly
broad, causing errors outside of coverage.py settings, as described in `issue
1481`_ and `issue 1345`_. This is now fixed, but in rare cases will require
changing your pyproject.toml to quote non-string values that use environment
substitution.
- An empty file has a coverage total of 100%, but used to fail with
``--fail-under``. This has been fixed, closing `issue 1470`_.
- The text report table no longer writes out two separator lines if there are
no files listed in the table. One is plenty.
- Fixed a mis-measurement of a strange use of wildcard alternatives in
match/case statements, closing `issue 1421`_.
- Fixed internal logic that prevented coverage.py from running on
implementations other than CPython or PyPy (`issue 1474`_).
- The deprecated ``[run] note`` setting has been completely removed.

`issue 1425`_.
- Starting with coverage.py 6.2, ``class`` statements were marked as a branch.
This wasn't right, and has been reverted, fixing `issue 1449`_. Note this
will very slightly reduce your coverage total if you are measuring branch
coverage.
- Packaging is now compliant with `PEP 517`_, closing `issue 1395`_.
- A new debug option ``--debug=pathmap`` shows details of the remapping of
paths that happens during combine due to the ``[paths]`` setting.
- Fix an internal problem with caching of invalid Python parsing. Found by
OSS-Fuzz, fixing their `bug 50381`_.

--------------------------
- Fix a failure when combining data files if the file names contained glob-like
patterns. Thanks, `Michael Krebs and Benjamin Schubert `_.
- Fix a messaging failure when combining Windows data files on a different
drive than the current directory, closing `issue 1428`_. Thanks, `Lorenzo

- Fix path calculations when running in the root directory, as you might do in
a Docker container. Thanks `Arthur Rio `_.

Version 6.4.2 โ 2022-07-12
--------------------------
- Updated for a small change in Python 3.11.0 beta 4: modules now start with a
line with line number 0, which is ignored. This line cannot be executed, so
coverage totals were thrown off. This line is now ignored by coverage.py,
but this also means that truly empty modules (like ``__init__.py``) have no
lines in them, rather than one phantom line. Fixes `issue 1419`_.
- Internal debugging data added to sys.modules is now an actual module, to
avoid confusing code that examines everything in sys.modules. Thanks,
`Yilei Yang `_.

Version 6.4.1 โ 2022-06-02
--------------------------
- Greatly improved performance on PyPy, and other environments that need the
pure Python trace function. Thanks, Carl Friedrich Bolz-Tereick (`pull
1381`_ and `pull 1388`_). Slightly improved performance when using the C
trace function, as most environments do. Closes `issue 1339`_.
- The conditions for using tomllib from the standard library have been made
more precise, so that 3.11 alphas will continue to work. Closes `issue
1390`_.

Version 6.4 โ 2022-05-22
------------------------
- A new setting, :ref:`config_run_sigterm`, controls whether a SIGTERM signal
handler is used. In 6.3, the signal handler was always installed, to capture
data at unusual process ends. Unfortunately, this introduced other problems
(see `issue 1310`_). Now the signal handler is only used if you opt-in by
setting ``[run] sigterm = true``.
- Small changes to the HTML report:
- Added links to next and previous file, and more keyboard shortcuts: ``[``
and ``]`` for next file and previous file; ``u`` for up to the index; and
``?`` to open/close the help panel. Thanks, `J. M. F. Tsang
`_.
- The time stamp and version are displayed at the top of the report. Thanks,
`Ammar Askar `_. Closes `issue 1351`_.
- A new debug option ``debug=sqldata`` adds more detail to ``debug=sql``,
logging all the data being written to the database.
- Previously, running ``coverage report`` (or any of the reporting commands) in
an empty directory would create a .coverage data file. Now they do not,
fixing `issue 1328`_.
- On Python 3.11, the ``[toml]`` extra no longer installs tomli, instead using
tomllib from the standard library. Thanks `Shantanu `_.
- In-memory CoverageData objects now properly update(), closing `issue 1323`_.

decorators like CPython 3.8: both the @-line and the def-line are traced.
Fixes `issue 1326`_.
- Debug: added ``pybehave`` to the list of :ref:`coverage debug `
and :ref:`cmd_run_debug` options.
- Fix: show an intelligible error message if ``--concurrency=multiprocessing``
is used without a configuration file. Closes `issue 1320`_.

Version 6.3.1 โ 2022-02-01
--------------------------
- Fix: deadlocks could occur when terminating processes. Some of these
deadlocks (described in `issue 1310`_) are now fixed.
- Fix: a signal handler was being set from multiple threads, causing an error:
"ValueError: signal only works in main thread". This is now fixed, closing
`issue 1312`_.
- Fix: ``--precision`` on the command-line was being ignored while considering
``--fail-under``. This is now fixed, thanks to
`Marcelo Trylesinski `_.
- Fix: releases no longer provide 3.11.0-alpha wheels. Coverage.py uses CPython
internal fields which are moving during the alpha phase. Fixes `issue 1316`_.

Version 6.3 โ 2022-01-25
------------------------
- Feature: Added the ``lcov`` command to generate reports in LCOV format.
Thanks, `Bradley Burns `_. Closes issues `587 `_
and `626 `_.
- Feature: the coverage data file can now be specified on the command line with
the ``--data-file`` option in any command that reads or writes data. This is
in addition to the existing ``COVERAGE_FILE`` environment variable. Closes
`issue 624`_. Thanks, `Nikita Bloshchanevich `_.
- Feature: coverage measurement data will now be written when a SIGTERM signal
is received by the process. This includes
:meth:`Process.terminate `,
and other ways to terminate a process. Currently this is only on Linux and
Mac; Windows is not supported. Fixes `issue 1307`_.
- Dropped support for Python 3.6, which reached end-of-life on 2021-12-23.
- Updated Python 3.11 support to 3.11.0a4, fixing `issue 1294`_.
- Fix: the coverage data file is now created in a more robust way, to avoid
problems when multiple processes are trying to write data at once. Fixes
issues `1303 `_ and `883 `_.
- Fix: a .gitignore file will only be written into the HTML report output
directory if the directory is empty. This should prevent certain unfortunate
accidents of writing the file where it is not wanted.
- Releases now have MacOS arm64 wheels for Apple Silicon, fixing `issue 1288`_.

Version 6.2 โ 2021-11-26
------------------------
- Feature: Now the ``--concurrency`` setting can have a list of values, so that
threads and another lightweight threading package can be measured together,
such as ``--concurrency=gevent,thread``. Closes `issue 1012`_ and `issue
1082`_. This also means that ``thread`` must be explicitly specified in some
cases that used to be implicit such as ``--concurrency=multiprocessing``,
which must be changed to ``--concurrency=multiprocessing,thread``.
- Fix: A module specified as the ``source`` setting is imported during startup,
before the user program imports it. This could cause problems if the rest of
the program isn't ready yet. For example, `issue 1203`_ describes a Django
setting that is accessed before settings have been configured. Now the early
import is wrapped in a try/except so errors then don't stop execution.
- Fix: A colon in a decorator expression would cause an exclusion to end too
early, preventing the exclusion of the decorated function. This is now fixed.
- Fix: The HTML report now will not overwrite a .gitignore file that already
exists in the HTML output directory (follow-on for `issue 1244
`_).
- API: The exceptions raised by Coverage.py have been specialized, to provide
finer-grained catching of exceptions by third-party code.
- API: Using ``suffix=False`` when constructing a Coverage object with
multiprocessing wouldn't suppress the data file suffix (`issue 989`_). This
is now fixed.
- Debug: The ``coverage debug data`` command will now sniff out combinable data
files, and report on all of them.
- Debug: The ``coverage debug`` command used to accept a number of topics at a
time, and show all of them, though this was never documented. This no longer
works, to allow for command-line options in the future.

Version 6.1.2 โ 2021-11-10
--------------------------
- Python 3.11 is supported (tested with 3.11.0a2). One still-open issue has to
do with `exits through with-statements `_.
- Fix: When remapping file paths through the ``[paths]`` setting while
combining, the ``[run] relative_files`` setting was ignored, resulting in
absolute paths for remapped file names (`issue 1147`_). This is now fixed.
- Fix: Complex conditionals over excluded lines could have incorrectly reported
a missing branch (`issue 1271`_). This is now fixed.
- Fix: More exceptions are now handled when trying to parse source files for
reporting. Problems that used to terminate coverage.py can now be handled
with ``[report] ignore_errors``. This helps with plugins failing to read
files (`django_coverage_plugin issue 78`_).
- Fix: Removed another vestige of jQuery from the source tarball
(`issue 840 `_).
- Fix: Added a default value for a new-to-6.x argument of an internal class.
This unsupported class is being used by coveralls (`issue 1273`_). Although
I'd rather not "fix" unsupported interfaces, it's actually nicer with a
default value.

Version 6.1.1 โ 2021-10-31
--------------------------
- Fix: The sticky header on the HTML report didn't work unless you had branch
coverage enabled. This is now fixed: the sticky header works for everyone.
(Do people still use coverage without branch measurement!? j/k)
- Fix: When using explicitly declared namespace packages, the "already imported
a file that will be measured" warning would be issued (`issue 888`_). This
is now fixed.
.. _issue 888: https://github.com/nedbat/coveragepy/issues/888
.. _changes_61:
Version 6.1 โ 2021-10-30
------------------------
- Deprecated: The ``annotate`` command and the ``Coverage.annotate`` function
will be removed in a future version, unless people let me know that they are
using it. Instead, the ``html`` command gives better-looking (and more
accurate) output, and the ``report -m`` command will tell you line numbers of
missing lines. Please get in touch if you have a reason to use ``annotate``
over those better options: ned@nedbatchelder.com.
- Feature: Coverage now sets an environment variable, ``COVERAGE_RUN`` when
running your code with the ``coverage run`` command. The value is not
important, and may change in the future. Closes `issue 553`_.
- Feature: The HTML report pages for Python source files now have a sticky
header so the file name and controls are always visible.
- Feature: The ``xml`` and ``json`` commands now describe what they wrote
where.
- Feature: The ``html``, ``combine``, ``xml``, and ``json`` commands all accept
a ``-q/--quiet`` option to suppress the messages they write to stdout about
what they are doing (`issue 1254`_).
- Feature: The ``html`` command writes a ``.gitignore`` file into the HTML
output directory, to prevent the report from being committed to git. If you
want to commit it, you will need to delete that file. Closes `issue 1244`_.
- Feature: Added support for PyPy 3.8.
- Fix: More generated code is now excluded from measurement. Code such as
`attrs`_ boilerplate, or doctest code, was being measured though the
synthetic line numbers meant they were never reported. Once Cython was
involved though, the generated .so files were parsed as Python, raising
syntax errors, as reported in `issue 1160`_. This is now fixed.
- Fix: When sorting human-readable names, numeric components are sorted
correctly: file10.py will appear after file9.py. This applies to file names,
module names, environment variables, and test contexts.
- Performance: Branch coverage measurement is faster, though you might only
notice on code that is executed many times, such as long-running loops.
- Build: jQuery is no longer used or vendored (`issue 840`_ and `issue 1118`_).
Huge thanks to Nils Kattenbeck (septatrix) for the conversion to vanilla
JavaScript in `pull request 1248`_.

Version 6.0.2 โ 2021-10-11
--------------------------
- Namespace packages being measured weren't properly handled by the new code
that ignores third-party packages. If the namespace package was installed, it
was ignored as a third-party package. That problem (`issue 1231`_) is now
fixed.
- Packages named as "source packages" (with ``source``, or ``source_pkgs``, or
pytest-cov's ``--cov``) might have been only partially measured. Their
top-level statements could be marked as un-executed, because they were
imported by coverage.py before measurement began (`issue 1232`_). This is
now fixed, but the package will be imported twice, once by coverage.py, then
again by your test suite. This could cause problems if importing the package
has side effects.
- The :meth:`.CoverageData.contexts_by_lineno` method was documented to return
a dict, but was returning a defaultdict. Now it returns a plain dict. It
also no longer returns negative numbered keys.

Version 6.0.1 โ 2021-10-06
--------------------------
- In 6.0, the coverage.py exceptions moved from coverage.misc to
coverage.exceptions. These exceptions are not part of the public supported
API, CoverageException is. But a number of other third-party packages were
importing the exceptions from coverage.misc, so they are now available from
there again (`issue 1226`_).
- Changed an internal detail of how tomli is imported, so that tomli can use
coverage.py for their own test suite (`issue 1228`_).
- Defend against an obscure possibility under code obfuscation, where a
function can have an argument called "self", but no local named "self"
(`pull request 1210`_). Thanks, Ben Carlsson.

Version 6.0 โ 2021-10-03
------------------------
- The ``coverage html`` command now prints a message indicating where the HTML
report was written. Fixes `issue 1195`_.
- The ``coverage combine`` command now prints messages indicating each data
file being combined. Fixes `issue 1105`_.
- The HTML report now includes a sentence about skipped files due to
``skip_covered`` or ``skip_empty`` settings. Fixes `issue 1163`_.
- Unrecognized options in the configuration file are no longer errors. They are
now warnings, to ease the use of coverage across versions. Fixes `issue
1035`_.
- Fix handling of exceptions through context managers in Python 3.10. A missing
exception is no longer considered a missing branch from the with statement.
Fixes `issue 1205`_.
- Fix another rarer instance of "Error binding parameter 0 - probably
unsupported type." (`issue 1010 `_).
- Creating a directory for the coverage data file now is safer against
conflicts when two coverage runs happen simultaneously (`pull 1220`_).
Thanks, Clรฉment Pit-Claudel.

Version 6.0b1 โ 2021-07-18
--------------------------
- Dropped support for Python 2.7, PyPy 2, and Python 3.5.
- Added support for the Python 3.10 ``match/case`` syntax.
- Data collection is now thread-safe. There may have been rare instances of
exceptions raised in multi-threaded programs.
- Plugins (like the `Django coverage plugin`_) were generating "Already
imported a file that will be measured" warnings about Django itself. These
have been fixed, closing `issue 1150`_.
- Warnings generated by coverage.py are now real Python warnings.
- Using ``--fail-under=100`` with coverage near 100% could result in the
self-contradictory message :code:`total of 100 is less than fail-under=100`.
This bug (`issue 1168`_) is now fixed.
- The ``COVERAGE_DEBUG_FILE`` environment variable now accepts ``stdout`` and
``stderr`` to write to those destinations.
- TOML parsing now uses the `tomli`_ library.
- Some minor changes to usually invisible details of the HTML report:
- Use a modern hash algorithm when fingerprinting, for high-security
environments (`issue 1189`_). When generating the HTML report, we save the
hash of the data, to avoid regenerating an unchanged HTML page. We used to
use MD5 to generate the hash, and now use SHA-3-256. This was never a
security concern, but security scanners would notice the MD5 algorithm and
raise a false alarm.
- Change how report file names are generated, to avoid leading underscores
(`issue 1167`_), to avoid rare file name collisions (`issue 584`_), and to
avoid file names becoming too long (`issue 580`_).

Version 5.6b1 โ 2021-04-13
--------------------------
Note: 5.6 final was never released. These changes are part of 6.0.
- Third-party packages are now ignored in coverage reporting. This solves a
few problems:
- Coverage will no longer report about other people's code (`issue 876`_).
This is true even when using ``--source=.`` with a venv in the current
directory.
- Coverage will no longer generate "Already imported a file that will be
measured" warnings about coverage itself (`issue 905`_).
- The HTML report uses j/k to move up and down among the highlighted chunks of
code. They used to highlight the current chunk, but 5.0 broke that behavior.
Now the highlighting is working again.
- The JSON report now includes ``percent_covered_display``, a string with the
total percentage, rounded to the same number of decimal places as the other
reports' totals.

.. _issue 905: https://github.com/nedbat/coveragepy/issues/905
.. _changes_55:
Version 5.5 โ 2021-02-28
------------------------
- ``coverage combine`` has a new option, ``--keep`` to keep the original data
files after combining them. The default is still to delete the files after
they have been combined. This was requested in `issue 1108`_ and implemented
in `pull request 1110`_. Thanks, รric Lariviรจre.
- When reporting missing branches in ``coverage report``, branches aren't
reported that jump to missing lines. This adds to the long-standing behavior
of not reporting branches from missing lines. Now branches are only reported
if both the source and destination lines are executed. Closes both `issue
1065`_ and `issue 955`_.
- Minor improvements to the HTML report:
- The state of the line visibility selector buttons is saved in local storage
so you don't have to fiddle with them so often, fixing `issue 1123`_.
- It has a little more room for line numbers so that 4-digit numbers work
well, fixing `issue 1124`_.
- Improved the error message when combining line and branch data, so that users
will be more likely to understand what's happening, closing `issue 803`_.

line, even if only one Python file is reported. This makes regex parsing
of the output easier. Thanks, Judson Neer. This had been requested a number
of times (`issue 1086`_, `issue 922`_, `issue 732`_).
- The ``skip_covered`` and ``skip_empty`` settings in the configuration file
can now be specified in the ``[html]`` section, so that text reports and HTML
reports can use separate settings. The HTML report will still use the
``[report]`` settings if there isn't a value in the ``[html]`` section.
Closes `issue 1090`_.
- Combining files on Windows across drives now works properly, fixing `issue
577`_. Thanks, `Valentin Lab `_.
- Fix an obscure warning from deep in the decimal module, as reported in
`issue 1084`_.
- Update to support Python 3.10 alphas in progress, including `PEP 626: Precise
line numbers for debugging and other tools `_.

Version 5.3.1 โ 2020-12-19
--------------------------
- When using ``--source`` on a large source tree, v5.x was slower than previous
versions. This performance regression is now fixed, closing `issue 1037`_.
- Mysterious SQLite errors can happen on PyPy, as reported in `issue 1010`_. An
immediate retry seems to fix the problem, although it is an unsatisfying
solution.
- The HTML report now saves the sort order in a more widely supported way,
fixing `issue 986`_. Thanks, Sebastiรกn Ramรญrez (`pull request 1066`_).
- The HTML report pages now have a :ref:`Sleepy Snake ` favicon.
- Wheels are now provided for manylinux2010, and for PyPy3 (pp36 and pp37).
- Continuous integration has moved from Travis and AppVeyor to GitHub Actions.

Version 5.3 โ 2020-09-13
------------------------
- The ``source`` setting has always been interpreted as either a file path or a
module, depending on which existed. If both interpretations were valid, it
was assumed to be a file path. The new ``source_pkgs`` setting can be used
to name a package to disambiguate this case. Thanks, Thomas Grainger. Fixes
`issue 268`_.
- If a plugin was disabled due to an exception, we used to still try to record
its information, causing an exception, as reported in `issue 1011`_. This is
now fixed.

Coverage.py is a tool for measuring code coverage of Python programs. It monitors your program,
noting which parts of the code have been executed, then analyzes the source to identify code
that could have been executed but was not.
Coverage measurement is typically used to gauge the effectiveness of tests. It can show which
parts of your code are being exercised by tests, and which are not.

do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside

that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,

liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

Coverage.py measures code coverage, typically during test execution. It uses
the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.
Coverage.py runs on these versions of Python:
.. PYVERSIONS
* Python 3.10 through 3.15 alpha, including free-threading.
* PyPy3 versions 3.10 and 3.11.
Documentation is on `Read the Docs`_. Code repository and issue tracker are on
`GitHub`_.
.. _Read the Docs: https://coverage.readthedocs.io/en/7.11.1/
.. _GitHub: https://github.com/nedbat/coveragepy
**New in 7.x:**
``[run] patch`` setting;
``--save-signal`` option;
``[run] core`` setting;
``[run] source_dirs`` setting;
``Coverage.branch_stats()``;
multi-line exclusion patterns;
function/class reporting;
experimental support for sys.monitoring;
dropped support for Python up to 3.9;
added ``Coverage.collect()`` context manager;
improved data combining;
``[run] exclude_also`` setting;
``report --format=``;
type annotations.
**New in 6.x:**
dropped support for Python 2.7, 3.5, and 3.6;
write data on SIGTERM;
added support for 3.10 match/case statements.

Many of these arguments duplicate and override values that can be
provided in a configuration file. Parameters that are missing here
will use values from the config file.
`data_file` is the base name of the data file to use. The config value
defaults to ".coverage". None can be provided to prevent writing a data
file. `data_suffix` is appended (with a dot) to `data_file` to create
the final file name. If `data_suffix` is simply True, then a suffix is
created with the machine and process identity included.
`cover_pylib` is a boolean determining whether Python code installed
with the Python interpreter is measured. This includes the Python
standard library and any packages installed with the interpreter.
If `auto_data` is true, then any existing data file will be read when
coverage measurement starts, and data will be saved automatically when
measurement stops.
If `timid` is true, then a slower and simpler trace function will be
used. This is important for some environments where manipulation of
tracing functions breaks the faster trace function.
If `branch` is true, then branch coverage will be measured in addition
to the usual statement coverage.
`config_file` determines what configuration file to read:
* If it is ".coveragerc", it is interpreted as if it were True,
for backward compatibility.
* If it is a string, it is the name of the file to read. If the
file can't be read, it is an error.
* If it is True, then a few standard files names are tried
(".coveragerc", "setup.cfg", "tox.ini"). It is not an error for
these files to not be found.
* If it is False, then no configuration file is read.
`source` is a list of file paths or package names. Only code located
in the trees indicated by the file paths or package names will be
measured.
`source_pkgs` is a list of package names. It works the same as
`source`, but can be used to name packages where the name can also be
interpreted as a file path.
`source_dirs` is a list of file paths. It works the same as
`source`, but raises an error if the path doesn't exist, rather
than being treated as a package name.
`include` and `omit` are lists of file name patterns. Files that match
`include` will be measured, files that match `omit` will not. Each
will also accept a single string argument.
`debug` is a list of strings indicating what debugging information is
desired.
`concurrency` is a string indicating the concurrency library being used
in the measured code. Without this, coverage.py will get incorrect
results if these libraries are in use. Valid strings are "greenlet",
"eventlet", "gevent", "multiprocessing", or "thread" (the default).
This can also be a list of these strings.
If `check_preimported` is true, then when coverage is started, the
already-imported files will be checked to see if they should be
measured by coverage. Importing measured files before coverage is
started can mean that code is missed.
`context` is a string to use as the :ref:`static context
` label for collected data.
If `messages` is true, some messages will be printed to stdout
indicating what is happening.
If `plugins` are passed, they are an iterable of function objects
accepting a `reg` object to register plugins, as described in
:ref:`api_plugin`. When they are provided, they will override the
plugins found in the coverage configuration file.
.. versionadded:: 4.0
The `concurrency` parameter.
.. versionadded:: 4.2
The `concurrency` parameter can now be a list of strings.
.. versionadded:: 5.0
The `check_preimported` and `context` parameters.
.. versionadded:: 5.3
The `source_pkgs` parameter.
.. versionadded:: 6.0
The `messages` parameter.

* Python has two ways to set the trace function: sys.settrace(fn), which
* takes a Python callable, and PyEval_SetTrace(func, obj), which takes
* a C function and a Python object. The way these work together is that
* sys.settrace(pyfn) calls PyEval_SetTrace(builtin_func, pyfn), using the
* Python callable as the object in PyEval_SetTrace. So sys.gettrace()
* simply returns the Python object used as the second argument to
* PyEval_SetTrace. So sys.gettrace() will return our self parameter, which
* means it must be callable to be used in sys.settrace().
*
* So we make ourself callable, equivalent to invoking our trace function.

the new trace function before it has a chance to get called. To

.. versionadded:: 4.0
Plug-in interfaces for coverage.py.
Coverage.py supports a few different kinds of plug-ins that change its
behavior:
* File tracers implement tracing of non-Python file types.
* Configurers add custom configuration, using Python code to change the
configuration.
* Dynamic context switchers decide when the dynamic context has changed, for
example, to record what test function produced the coverage.
To write a coverage.py plug-in, create a module with a subclass of
:class:`~coverage.CoveragePlugin`. You will override methods in your class to
participate in various aspects of coverage.py's processing.
Different types of plug-ins have to override different methods.
Any plug-in can optionally implement :meth:`~coverage.CoveragePlugin.sys_info`
to provide debugging information about their operation.
Your module must also contain a ``coverage_init`` function that registers an
instance of your plug-in class::
import coverage
class MyPlugin(coverage.CoveragePlugin):
...
def coverage_init(reg, options):
reg.add_file_tracer(MyPlugin())
You use the `reg` parameter passed to your ``coverage_init`` function to
register your plug-in object. The registration method you call depends on
what kind of plug-in it is.
If your plug-in takes options, the `options` parameter is a dictionary of your
plug-in's options from the coverage.py configuration file. Use them however
you want to configure your object before registering it.
Coverage.py will store its own information on your plug-in object, using
attributes whose names start with ``_coverage_``. Don't be startled.
.. warning::
Plug-ins are imported by coverage.py before it begins measuring code.
If you write a plugin in your own project, it might import your product
code before coverage.py can start measuring. This can result in your
own code being reported as missing.
One solution is to put your plugins in your project tree, but not in
your importable Python package.
.. _file_tracer_plugins:
File Tracers
============
File tracers implement measurement support for non-Python files. File tracers
implement the :meth:`~coverage.CoveragePlugin.file_tracer` method to claim
files and the :meth:`~coverage.CoveragePlugin.file_reporter` method to report
on those files.
In your ``coverage_init`` function, use the ``add_file_tracer`` method to
register your file tracer.
.. _configurer_plugins:
Configurers
===========
.. versionadded:: 4.5
Configurers modify the configuration of coverage.py during start-up.
Configurers implement the :meth:`~coverage.CoveragePlugin.configure` method to
change the configuration.
In your ``coverage_init`` function, use the ``add_configurer`` method to
register your configurer.
.. _dynamic_context_plugins:
Dynamic Context Switchers
=========================
.. versionadded:: 5.0
Dynamic context switcher plugins implement the
:meth:`~coverage.CoveragePlugin.dynamic_context` method to dynamically compute
the context label for each measured frame.
Computed context labels are useful when you want to group measured data without
modifying the source code.
For example, you could write a plugin that checks `frame.f_code` to inspect
the currently executed method, and set the context label to a fully qualified
method name if it's an instance method of `unittest.TestCase` and the method
name starts with 'test'. Such a plugin would provide basic coverage grouping
by test and could be used with test runners that have no built-in coveragepy
support.
In your ``coverage_init`` function, use the ``add_dynamic_context`` method to
register your dynamic context switcher.

Plug-in type: file tracer.
Every Python source file is offered to your plug-in to give it a chance
to take responsibility for tracing the file. If your plug-in can
handle the file, it should return a :class:`FileTracer` object.
Otherwise return None.
There is no way to register your plug-in for particular files.
Instead, this method is invoked for all files as they are executed,
and the plug-in decides whether it can trace the file or not.
Be prepared for `filename` to refer to all kinds of files that have
nothing to do with your plug-in.
The file name will be a Python file being executed. There are two
broad categories of behavior for a plug-in, depending on the kind of
files your plug-in supports:
* Static file names: each of your original source files has been
converted into a distinct Python file. Your plug-in is invoked with
the Python file name, and it maps it back to its original source
file.
* Dynamic file names: all of your source files are executed by the same
Python file. In this case, your plug-in implements
:meth:`FileTracer.dynamic_source_filename` to provide the actual
source file for each execution frame.
`filename` is a string, the path to the file being considered. This is
the absolute real path to the file. If you are comparing to other
paths, be sure to take this into account.

class CoverageData:
"""Manages collected coverage data, including file storage.
This class is the public supported API to the data that coverage.py
collects during program execution. It includes information about what code
was executed. It does not include information from the analysis phase, to
determine what lines could have been executed, or what lines were not
executed.
.. note::
The data file is currently a SQLite database file, with a
:ref:`documented schema `. The schema is subject to change
though, so be careful about querying it directly. Use this API if you
can to isolate yourself from changes.
There are a number of kinds of data that can be collected:
* **lines**: the line numbers of source lines that were executed.
These are always available.
* **arcs**: pairs of source and destination line numbers for transitions
between source lines. These are only available if branch coverage was
used.
* **file tracer names**: the module names of the file tracer plugins that
handled each file in the data.
Lines, arcs, and file tracer names are stored for each source file. File
names in this API are case-sensitive, even on platforms with
case-insensitive file systems.
A data file either stores lines, or arcs, but not both.
A data file is associated with the data when the :class:`CoverageData`
is created, using the parameters `basename`, `suffix`, and `no_disk`. The
base name can be queried with :meth:`base_filename`, and the actual file
name being used is available from :meth:`data_filename`.
To read an existing coverage.py data file, use :meth:`read`. You can then
access the line, arc, or file tracer data with :meth:`lines`, :meth:`arcs`,
or :meth:`file_tracer`.
The :meth:`has_arcs` method indicates whether arc data is available. You
can get a set of the files in the data with :meth:`measured_files`. As
with most Python containers, you can determine if there is any data at all
by using this object as a boolean value.
The contexts for each line in a file can be read with
:meth:`contexts_by_lineno`.
To limit querying to certain contexts, use :meth:`set_query_context` or
:meth:`set_query_contexts`. These will narrow the focus of subsequent
:meth:`lines`, :meth:`arcs`, and :meth:`contexts_by_lineno` calls. The set
of all measured context names can be retrieved with
:meth:`measured_contexts`.
Most data files will be created by coverage.py itself, but you can use
methods here to create data files if you like. The :meth:`add_lines`,
:meth:`add_arcs`, and :meth:`add_file_tracers` methods add data, in ways
that are convenient for coverage.py.
To record data for contexts, use :meth:`set_context` to set a context to
be used for subsequent :meth:`add_lines` and :meth:`add_arcs` calls.
To add a source file without any measured data, use :meth:`touch_file`,
or :meth:`touch_files` for a list of such files.
Write the data to its file with :meth:`write`.
You can clear the data in memory with :meth:`erase`. Data for specific
files can be removed from the database with :meth:`purge_files`.
Two data collections can be combined by using :meth:`update` on one
:class:`CoverageData`, passing it the other.
Data in a :class:`CoverageData` can be serialized and deserialized with
:meth:`dumps` and :meth:`loads`.
The methods used during the coverage.py collection phase
(:meth:`add_lines`, :meth:`add_arcs`, :meth:`set_context`, and
:meth:`add_file_tracers`) are thread-safe. Other methods may not be.

Coverage.py measures code coverage, typically during test execution. It uses
the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.
Coverage.py runs on these versions of Python:
.. PYVERSIONS
* Python 3.10 through 3.15 alpha, including free-threading.
* PyPy3 versions 3.10 and 3.11.
Documentation is on `Read the Docs`_. Code repository and issue tracker are on
`GitHub`_.
.. _Read the Docs: https://coverage.readthedocs.io/en/7.11.1/
.. _GitHub: https://github.com/nedbat/coveragepy
**New in 7.x:**
``[run] patch`` setting;
``--save-signal`` option;
``[run] core`` setting;
``[run] source_dirs`` setting;
``Coverage.branch_stats()``;
multi-line exclusion patterns;
function/class reporting;
experimental support for sys.monitoring;
dropped support for Python up to 3.9;
added ``Coverage.collect()`` context manager;
improved data combining;
``[run] exclude_also`` setting;
``report --format=``;
type annotations.
**New in 6.x:**
dropped support for Python 2.7, 3.5, and 3.6;
write data on SIGTERM;
added support for 3.10 match/case statements.

Coverage.py API
===============
There are a few different ways to use coverage.py programmatically.
The API to coverage.py is in a module called :mod:`coverage`. Most of the
interface is in the :class:`coverage.Coverage` class. Methods on the Coverage
object correspond roughly to operations available in the command line
interface. For example, a simple use would be::
import coverage
cov = coverage.Coverage()
cov.start()
# .. call your code ..
cov.stop()
cov.save()
cov.html_report()
Any of the methods can raise specialized exceptions described in
:ref:`api_exceptions`.
Coverage.py supports plugins that can change its behavior, to collect
information from non-Python files, or to perform complex configuration. See
:ref:`api_plugin` for details.
If you want to access the data that coverage.py has collected, the
:class:`coverage.CoverageData` class provides an API to read coverage.py data
files.
.. warning::
Only the published documented portions of the API are supported. Other
names you may find in modules or objects can change their behavior at any
time. Please limit yourself to documented methods to avoid problems.
All internal code in coverage.py has docstrings; this does not make them
part of the public supported API. Many internal names have no leading
underscore; this does not make them part of the public supported API. If
classes or functions are not documented in this published documentation,
they are not supported.
For more intensive data use, you might want to access the coverage.py database
file directly. The schema is subject to change, so this is for advanced uses
only. :ref:`dbschema` explains more.

===========================
Branch coverage measurement
===========================
.. highlight:: python
:linenothreshold: 5
In addition to the usual statement coverage, coverage.py also supports branch
coverage measurement. Where a line in your program could jump to more than one
next line, coverage.py tracks which of those destinations are actually visited,
and flags lines that haven't visited all of their possible destinations.
For example::
def my_partial_fn(x):
if x:
y = 10
return y
my_partial_fn(1)
In this code, line 2 is an ``if`` statement which can go next to either line 3
or line 4. Statement coverage would show all lines of the function as executed.
But the if was never evaluated as false, so line 2 never jumps to line 4.
Branch coverage will flag this code as not fully covered because of the missing
jump from line 2 to line 4. This is known as a partial branch.
How to measure branch coverage
------------------------------
To measure branch coverage, run coverage.py with the ``--branch`` flag::
coverage run --branch myprog.py
When you report on the results with ``coverage report`` or ``coverage html``,
the percentage of branch possibilities taken will be included in the percentage
covered total for each file. The coverage percentage for a file is the actual
executions divided by the execution opportunities. Each line in the file is an
execution opportunity, as is each branch destination.
The HTML report gives information about which lines had missing branches. Lines
that were missing some branches are shown in yellow, with an annotation at the
far right showing branch destination line numbers that were not exercised.
The XML and JSON reports produced by ``coverage xml`` and ``coverage json``
also include branch information, including separate statement and branch
coverage percentages.
How it works
------------
When measuring branches, coverage.py collects pairs of line numbers, a source
and destination for each transition from one line to another. Static analysis
of the source provides a list of possible transitions. Comparing the measured
to the possible indicates missing branches.
The idea of tracking how lines follow each other was from `Titus Brown`__.
Thanks, Titus!
__ http://ivory.idyll.org/blog
Excluding code
--------------
If you have :ref:`excluded code `, a conditional will not be counted
as a branch if one of its choices is excluded::
def only_one_choice(x):
if x:
blah1()
blah2()
else: # pragma: no cover
# x is always true.
blah3()
Because the ``else`` clause is excluded, the ``if`` only has one possible next
line, so it isn't considered a branch at all.
Structurally partial branches
-----------------------------
Sometimes branching constructs are used in unusual ways that don't actually
branch. For example::
while True:
if cond:
break
do_something()
Here the while loop will never exit normally, so it doesn't take both of its
"possible" branches. For some of these constructs, such as "while True:" and
"if 0:", coverage.py understands what is going on. In these cases, the line
will not be marked as a partial branch.
But there are many ways in your own code to write intentionally partial
branches, and you don't want coverage.py pestering you about them. You can
tell coverage.py that you don't want them flagged by marking them with a
pragma::
i = 0
while i < 999999999: # pragma: no branch
if eventually():
break
Here the while loop will never complete because the break will always be taken
at some point. Coverage.py can't work that out on its own, but the "no branch"
pragma indicates that the branch is known to be partial, and the line is not
flagged.
Generator expressions
=====================
Generator expressions may also report partial branch coverage. Consider the
following example::
value = next(i in range(1))
While we might expect this line of code to be reported as covered, the
generator did not iterate until ``StopIteration`` is raised, the indication
that the loop is complete. This is another case
where adding ``# pragma: no branch`` may be desirable.

Version 5.2.1 โ 2020-07-23
--------------------------
- The dark mode HTML report still used light colors for the context listing,
making them unreadable (`issue 1009`_). This is now fixed.
- The time stamp on the HTML report now includes the time zone. Thanks, Xie
Yanbo (`pull request 960`_).

Version 5.2 โ 2020-07-05
------------------------
- The HTML report has been redesigned by Vince Salvino. There is now a dark
mode, the code text is larger, and system sans serif fonts are used, in
addition to other small changes (`issue 858`_ and `pull request 931`_).
- The ``coverage report`` and ``coverage html`` commands now accept a
``--precision`` option to control the number of decimal points displayed.
Thanks, Teake Nutma (`pull request 982`_).
- The ``coverage report`` and ``coverage html`` commands now accept a
``--no-skip-covered`` option to negate ``--skip-covered``. Thanks, Anthony
Sottile (`issue 779`_ and `pull request 932`_).
- The ``--skip-empty`` option is now available for the XML report, closing
`issue 976`_.
- The ``coverage report`` command now accepts a ``--sort`` option to specify
how to sort the results. Thanks, Jerin Peter George (`pull request 1005`_).
- If coverage fails due to the coverage total not reaching the ``--fail-under``
value, it will now print a message making the condition clear. Thanks,
Naveen Yadav (`pull request 977`_).
- TOML configuration files with non-ASCII characters would cause errors on
Windows (`issue 990`_). This is now fixed.
- The output of ``--debug=trace`` now includes information about how the
``--source`` option is being interpreted, and the module names being
considered.

------------------------
- The JSON report now includes counts of covered and missing branches. Thanks,
Salvatore Zagaria.
- On Python 3.8, try-finally-return reported wrong branch coverage with
decorated async functions (`issue 964`_). This is now fixed. Thanks, Kjell
Braden.
- The :meth:`~coverage.Coverage.get_option` and
:meth:`~coverage.Coverage.set_option` methods can now manipulate the

Version 5.0.4 โ 2020-03-16
--------------------------
- If using the ``[run] relative_files`` setting, the XML report will use
relative files in the ```` elements indicating the location of source
code. Closes `issue 948`_.
- The textual summary report could report missing lines with negative line
numbers on PyPy3 7.1 (`issue 943`_). This is now fixed.
- Windows wheels for Python 3.8 were incorrectly built, but are now fixed.
(`issue 949`_)
- Updated Python 3.9 support to 3.9a4.
- HTML reports couldn't be sorted if localStorage wasn't available. This is now
fixed: sorting works even though the sorting setting isn't retained. (`issue
944`_ and `pull request 945`_). Thanks, Abdeali Kothari.

Version 5.0.3 โ 2020-01-12
--------------------------
- A performance improvement in 5.0.2 didn't work for test suites that changed
directory before combining data, causing "Couldn't use data file: no such
table: meta" errors (`issue 916`_). This is now fixed.
- Coverage could fail to run your program with some form of "ModuleNotFound" or
"ImportError" trying to import from the current directory. This would happen
if coverage had been packaged into a zip file (for example, on Windows), or
was found indirectly (for example, by pyenv-virtualenv). A number of
different scenarios were described in `issue 862`_ which is now fixed. Huge
thanks to Agbonze O. Jeremiah for reporting it, and Alexander Waters and
George-Cristian Bรฎrzan for protracted debugging sessions.
- Added the "premain" debug option.
- Added SQLite compile-time options to the "debug sys" output.

.. _changes_502:
Version 5.0.2 โ 2020-01-05
--------------------------
- Programs that used multiprocessing and changed directories would fail under
coverage. This is now fixed (`issue 890`_). A side effect is that debug
information about the config files read now shows absolute paths to the
files.
- When running programs as modules (``coverage run -m``) with ``--source``,
some measured modules were imported before coverage starts. This resulted in
unwanted warnings ("Already imported a file that will be measured") and a
reduction in coverage totals (`issue 909`_). This is now fixed.
- If no data was collected, an exception about "No data to report" could happen
instead of a 0% report being created (`issue 884`_). This is now fixed.
- The handling of source files with non-encodable file names has changed.
Previously, if a file name could not be encoded as UTF-8, an error occurred,
as described in `issue 891`_. Now, those files will not be measured, since
their data would not be recordable.
- A new warning ("dynamic-conflict") is issued if two mechanisms are trying to
change the dynamic context. Closes `issue 901`_.
- ``coverage run --debug=sys`` would fail with an AttributeError. This is now
fixed (`issue 907`_).

Version 5.0.1 โ 2019-12-22
--------------------------
- If a 4.x data file is the cause of a "file is not a database" error, then use
a more specific error message, "Looks like a coverage 4.x data file, are you
mixing versions of coverage?" Helps diagnose the problems described in
`issue 886`_.
- Measurement contexts and relative file names didn't work together, as
reported in `issue 899`_ and `issue 900`_. This is now fixed, thanks to
David Szotten.
- When using ``coverage run --concurrency=multiprocessing``, all data files
should be named with parallel-ready suffixes. 5.0 mistakenly named the main
process' file with no suffix when using ``--append``. This is now fixed,
closing `issue 880`_.
- Fixed a problem on Windows when the current directory is changed to a
different drive (`issue 895`_). Thanks, Olivier Grisel.
- Updated Python 3.9 support to 3.9a2.

Version 5.0 โ 2019-12-14
------------------------
Nothing new beyond 5.0b2.
A summary of major changes in 5.0 since 4.5.x is in see :ref:`whatsnew5x`.
.. _changes_50b2:
Version 5.0b2 โ 2019-12-08
--------------------------
- An experimental ``[run] relative_files`` setting tells coverage to store
relative file names in the data file. This makes it easier to run tests in
one (or many) environments, and then report in another. It has not had much
real-world testing, so it may change in incompatible ways in the future.
- When constructing a :class:`coverage.Coverage` object, `data_file` can be
specified as None to prevent writing any data file at all. In previous
versions, an explicit `data_file=None` argument would use the default of
".coverage". Fixes `issue 871`_.
- Python files run with ``-m`` now have ``__spec__`` defined properly. This
fixes `issue 745`_ (about not being able to run unittest tests that spawn
subprocesses), and `issue 838`_, which described the problem directly.
- The ``[paths]`` configuration section is now ordered. If you specify more
than one list of patterns, the first one that matches will be used. Fixes
`issue 649`_.
- The :func:`.coverage.numbits.register_sqlite_functions` function now also
registers `numbits_to_nums` for use in SQLite queries. Thanks, Simon
Willison.
- Python 3.9a1 is supported.
- Coverage.py has a mascot: :ref:`Sleepy Snake `.

Version 5.0b1 โ 2019-11-11
--------------------------
- The HTML and textual reports now have a ``--skip-empty`` option that skips
files with no statements, notably ``__init__.py`` files. Thanks, Reya B.
- Configuration can now be read from `TOML`_ files. This requires installing
coverage.py with the ``[toml]`` extra. The standard "pyproject.toml" file
will be read automatically if no other configuration file is found, with
settings in the ``[tool.coverage.]`` namespace. Thanks to Frazer McLean for
implementation and persistence. Finishes `issue 664`_.
- The ``[run] note`` setting has been deprecated. Using it will result in a
warning, and the note will not be written to the data file. The
corresponding :class:`.CoverageData` methods have been removed.
- The HTML report has been reimplemented (no more table around the source
code). This allowed for a better presentation of the context information,
hopefully resolving `issue 855`_.
- Added sqlite3 module version information to ``coverage debug sys`` output.
- Asking the HTML report to show contexts (``[html] show_contexts=True`` or
``coverage html --show-contexts``) will issue a warning if there were no
contexts measured (`issue 851`_).

.. _changes_50a8:
Version 5.0a8 โ 2019-10-02
--------------------------
- The :class:`.CoverageData` API has changed how queries are limited to
specific contexts. Now you use :meth:`.CoverageData.set_query_context` to
set a single exact-match string, or :meth:`.CoverageData.set_query_contexts`
to set a list of regular expressions to match contexts. This changes the
command-line ``--contexts`` option to use regular expressions instead of
filename-style wildcards.
.. _changes_50a7:
Version 5.0a7 โ 2019-09-21
--------------------------
- Data can now be "reported" in JSON format, for programmatic use, as requested
in `issue 720`_. The new ``coverage json`` command writes raw and summarized
data to a JSON file. Thanks, Matt Bachmann.
- Dynamic contexts are now supported in the Python tracer, which is important
for PyPy users. Closes `issue 846`_.
- The compact line number representation introduced in 5.0a6 is called a
"numbits." The :mod:`coverage.numbits` module provides functions for working
with them.
- The reporting methods used to permanently apply their arguments to the
configuration of the Coverage object. Now they no longer do. The arguments
affect the operation of the method, but do not persist.
- A class named "test_something" no longer confuses the ``test_function``
dynamic context setting. Fixes `issue 829`_.
- Fixed an unusual tokenizing issue with backslashes in comments. Fixes
`issue 822`_.
- ``debug=plugin`` didn't properly support configuration or dynamic context
plugins, but now it does, closing `issue 834`_.

Version 5.0a6 โ 2019-07-16
--------------------------
- Reporting on contexts. Big thanks to Stephan Richter and Albertas Agejevas
for the contribution.
- The ``--contexts`` option is available on the ``report`` and ``html``
commands. It's a comma-separated list of shell-style wildcards, selecting
the contexts to report on. Only contexts matching one of the wildcards
will be included in the report.
- The ``--show-contexts`` option for the ``html`` command adds context
information to each covered line. Hovering over the "ctx" marker at the
end of the line reveals a list of the contexts that covered the line.
- Database changes:
- Line numbers are now stored in a much more compact way. For each file and
context, a single binary string is stored with a bit per line number. This
greatly improves memory use, but makes ad-hoc use difficult.
- Dynamic contexts with no data are no longer written to the database.
- SQLite data storage is now faster. There's no longer a reason to keep the
JSON data file code, so it has been removed.
- Changes to the :class:`.CoverageData` interface:
- The new :meth:`.CoverageData.dumps` method serializes the data to a string,
and a corresponding :meth:`.CoverageData.loads` method reconstitutes this
data. The format of the data string is subject to change at any time, and
so should only be used between two installations of the same version of
coverage.py.
- The :class:`CoverageData constructor<.CoverageData>` has a new
argument, `no_disk` (default: False). Setting it to True prevents writing
any data to the disk. This is useful for transient data objects.
- Added the class method :meth:`.Coverage.current` to get the latest started
Coverage instance.
- Multiprocessing support in Python 3.8 was broken, but is now fixed. Closes
`issue 828`_.
- Error handling during reporting has changed slightly. All reporting methods
now behave the same. The ``--ignore-errors`` option keeps errors from
stopping the reporting, but files that couldn't parse as Python will always
be reported as warnings. As with other warnings, you can suppress them with
the ``[run] disable_warnings`` configuration setting.
- Coverage.py no longer fails if the user program deletes its current
directory. Fixes `issue 806`_. Thanks, Dan Hemberger.
- The scrollbar markers in the HTML report now accurately show the highlighted
lines, regardless of what categories of line are highlighted.
- The hack to accommodate ShiningPanda_ looking for an obsolete internal data
file has been removed, since ShiningPanda 0.22 fixed it four years ago.
- The deprecated `Reporter.file_reporters` property has been removed.

Version 5.0a5 โ 2019-05-07
--------------------------
- Drop support for Python 3.4
- Dynamic contexts can now be set two new ways, both thanks to Justas
Sadzeviฤius.
- A plugin can implement a ``dynamic_context`` method to check frames for
whether a new context should be started. See
:ref:`dynamic_context_plugins` for more details.
- Another tool (such as a test runner) can use the new
:meth:`.Coverage.switch_context` method to explicitly change the context.
- The ``dynamic_context = test_function`` setting now works with Python 2
old-style classes, though it only reports the method name, not the class it
was defined on. Closes `issue 797`_.
- ``fail_under`` values more than 100 are reported as errors. Thanks to Mike
Fiedler for closing `issue 746`_.
- The "missing" values in the text output are now sorted by line number, so
that missing branches are reported near the other lines they affect. The
values used to show all missing lines, and then all missing branches.
- Access to the SQLite database used for data storage is now thread-safe.
Thanks, Stephan Richter. This closes `issue 702`_.
- Combining data stored in SQLite is now about twice as fast, fixing `issue
761`_. Thanks, Stephan Richter.
- The ``filename`` attribute on :class:`.CoverageData` objects has been made
private. You can use the ``data_filename`` method to get the actual file
name being used to store data, and the ``base_filename`` method to get the
original filename before parallelizing suffixes were added. This is part of
fixing `issue 708`_.
- Line numbers in the HTML report now align properly with source lines, even
when Chrome's minimum font size is set, fixing `issue 748`_. Thanks Wen Ye.

Version 5.0a4 โ 2018-11-25
--------------------------
- You can specify the command line to run your program with the ``[run]
command_line`` configuration setting, as requested in `issue 695`_.
- Coverage will create directories as needed for the data file if they don't
exist, closing `issue 721`_.
- The ``coverage run`` command has always adjusted the first entry in sys.path,
to properly emulate how Python runs your program. Now this adjustment is
skipped if sys.path[0] is already different than Python's default. This
fixes `issue 715`_.
- Improvements to context support:
- The "no such table: meta" error is fixed.: `issue 716`_.
- Combining data files is now much faster.
- Python 3.8 (as of today!) passes all tests.

.. _changes_50a3:
Version 5.0a3 โ 2018-10-06
--------------------------
- Context support: static contexts let you specify a label for a coverage run,
which is recorded in the data, and retained when you combine files. See
:ref:`contexts` for more information.
- Dynamic contexts: specifying ``[run] dynamic_context = test_function`` in the
config file will record the test function name as a dynamic context during
execution. This is the core of "Who Tests What" (`issue 170`_). Things to
note:
- There is no reporting support yet. Use SQLite to query the .coverage file
for information. Ideas are welcome about how reporting could be extended
to use this data.
- There's a noticeable slow-down before any test is run.
- Data files will now be roughly N times larger, where N is the number of
tests you have. Combining data files is therefore also N times slower.
- No other values for ``dynamic_context`` are recognized yet. Let me know
what else would be useful. I'd like to use a pytest plugin to get better
information directly from pytest, for example.
.. _issue 170: https://github.com/nedbat/coveragepy/issues/170
- Environment variable substitution in configuration files now supports two
syntaxes for controlling the behavior of undefined variables: if ``VARNAME``
is not defined, ``${VARNAME?}`` will raise an error, and ``${VARNAME-default
value}`` will use "default value".
- Partial support for Python 3.8, which has not yet released an alpha. Fixes
`issue 707`_ and `issue 714`_.
.. _issue 707: https://github.com/nedbat/coveragepy/issues/707
.. _issue 714: https://github.com/nedbat/coveragepy/issues/714
.. _changes_50a2:
Version 5.0a2 โ 2018-09-03
--------------------------
- Coverage's data storage has changed. In version 4.x, .coverage files were
basically JSON. Now, they are SQLite databases. This means the data file
can be created earlier than it used to. A large amount of code was
refactored to support this change.
- Because the data file is created differently than previous releases, you
may need ``parallel=true`` where you didn't before.
- The old data format is still available (for now) by setting the environment
variable ``COVERAGE_STORAGE=json``. Please tell me if you think you need to
keep the JSON format.
- The database schema is guaranteed to change in the future, to support new
features. I'm looking for opinions about making the schema part of the
public API to coverage.py or not.
- Development moved from `Bitbucket`_ to `GitHub`_.
- HTML files no longer have trailing and extra white space.
- The sort order in the HTML report is stored in local storage rather than
cookies, closing `issue 611`_. Thanks, Federico Bond.
- pickle2json, for converting v3 data files to v4 data files, has been removed.

Version 5.0a1 โ 2018-06-05
--------------------------
- Coverage.py no longer supports Python 2.6 or 3.3.
- The location of the configuration file can now be specified with a
``COVERAGE_RCFILE`` environment variable, as requested in `issue 650`_.
- Namespace packages are supported on Python 3.7, where they used to cause
TypeErrors about path being None. Fixes `issue 700`_.
- A new warning (``already-imported``) is issued if measurable files have
already been imported before coverage.py started measurement. See
:ref:`cmd_warnings` for more information.
- Running coverage many times for small runs in a single process should be
faster, closing `issue 625`_. Thanks, David MacIver.
- Large HTML report pages load faster. Thanks, Pankaj Pandey.

Version 4.5.1 โ 2018-02-10
--------------------------
- Now that 4.5 properly separated the ``[run] omit`` and ``[report] omit``
settings, an old bug has become apparent. If you specified a package name
for ``[run] source``, then omit patterns weren't matched inside that package.
This bug (`issue 638`_) is now fixed.
- On Python 3.7, reporting about a decorated function with no body other than a
docstring would crash coverage.py with an IndexError (`issue 640`_). This is
now fixed.
- Configurer plugins are now reported in the output of ``--debug=sys``.
.. _issue 638: https://github.com/nedbat/coveragepy/issues/638
.. _issue 640: https://github.com/nedbat/coveragepy/issues/640
.. _changes_45:
Version 4.5 โ 2018-02-03
------------------------
- A new kind of plugin is supported: configurers are invoked at start-up to
allow more complex configuration than the .coveragerc file can easily do.
See :ref:`api_plugin` for details. This solves the complex configuration
problem described in `issue 563`_.
- The ``fail_under`` option can now be a float. Note that you must specify the
``[report] precision`` configuration option for the fractional part to be
used. Thanks to Lars Hupfeldt Nielsen for help with the implementation.
Fixes `issue 631`_.
- The ``include`` and ``omit`` options can be specified for both the ``[run]``
and ``[report]`` phases of execution. 4.4.2 introduced some incorrect
interactions between those phases, where the options for one were confused
for the other. This is now corrected, fixing `issue 621`_ and `issue 622`_.
Thanks to Daniel Hahler for seeing more clearly than I could.
- The ``coverage combine`` command used to always overwrite the data file, even
when no data had been read from apparently combinable files. Now, an error
is raised if we thought there were files to combine, but in fact none of them
could be used. Fixes `issue 629`_.
- The ``coverage combine`` command could get confused about path separators
when combining data collected on Windows with data collected on Linux, as
described in `issue 618`_. This is now fixed: the result path always uses
the path separator specified in the ``[paths]`` result.
- On Windows, the HTML report could fail when source trees are deeply nested,
due to attempting to create HTML filenames longer than the 250-character
maximum. Now filenames will never get much larger than 200 characters,
fixing `issue 627`_. Thanks to Alex Sandro for helping with the fix.

Version 4.4.2 โ 2017-11-05
--------------------------
- Support for Python 3.7. In some cases, class and module docstrings are no
longer counted in statement totals, which could slightly change your total
results.
- Specifying both ``--source`` and ``--include`` no longer silently ignores the
include setting, instead it displays a warning. Thanks, Loรฏc Dachary. Closes
`issue 265`_ and `issue 101`_.
- Fixed a race condition when saving data and multiple threads are tracing
(`issue 581`_). It could produce a "dictionary changed size during iteration"
RuntimeError. I believe this mostly but not entirely fixes the race
condition. A true fix would likely be too expensive. Thanks, Peter Baughman
for the debugging, and Olivier Grisel for the fix with tests.
- Configuration values which are file paths will now apply tilde-expansion,
closing `issue 589`_.
- Now secondary config files like tox.ini and setup.cfg can be specified
explicitly, and prefixed sections like `[coverage:run]` will be read. Fixes
`issue 588`_.
- Be more flexible about the command name displayed by help, fixing
`issue 600`_. Thanks, Ben Finney.

.. _changes_44:
Version 4.4 โ 2017-05-07
------------------------
- Reports could produce the wrong file names for packages, reporting ``pkg.py``
instead of the correct ``pkg/__init__.py``. This is now fixed. Thanks, Dirk
Thomas.
- XML reports could produce ```` and ```` lines that together
didn't specify a valid source file path. This is now fixed. (`issue 526`_)
- Namespace packages are no longer warned as having no code. (`issue 572`_)
- Code that uses ``sys.settrace(sys.gettrace())`` in a file that wasn't being
coverage-measured would prevent correct coverage measurement in following
code. An example of this was running doctests programmatically. This is now
fixed. (`issue 575`_)
- Errors printed by the ``coverage`` command now go to stderr instead of
stdout.
- Running ``coverage xml`` in a directory named with non-ASCII characters would
fail under Python 2. This is now fixed. (`issue 573`_)

Version 4.4b1 โ 2017-04-04
--------------------------
- Some warnings can now be individually disabled. Warnings that can be
disabled have a short name appended. The ``[run] disable_warnings`` setting
takes a list of these warning names to disable. Closes both `issue 96`_ and
`issue 355`_.
- The XML report now includes attributes from version 4 of the Cobertura XML
format, fixing `issue 570`_.
- In previous versions, calling a method that used collected data would prevent
further collection. For example, `save()`, `report()`, `html_report()`, and
others would all stop collection. An explicit `start()` was needed to get it
going again. This is no longer true. Now you can use the collected data and
also continue measurement. Both `issue 79`_ and `issue 448`_ described this
problem, and have been fixed.
- Plugins can now find un-executed files if they choose, by implementing the
`find_executable_files` method. Thanks, Emil Madsen.
- Minimal IronPython support. You should be able to run IronPython programs
under ``coverage run``, though you will still have to do the reporting phase
with CPython.
- Coverage.py has long had a special hack to support CPython's need to measure
the coverage of the standard library tests. This code was not installed by
kitted versions of coverage.py. Now it is.

- Python 2.6 support was broken due to a testing exception imported for the
benefit of the coverage.py test suite. Properly conditionalizing it fixed
`issue 554`_ so that Python 2.6 works again.
.. _issue 554: https://github.com/nedbat/coveragepy/issues/554
.. _changes_432:
Version 4.3.2 โ 2017-01-16
--------------------------
- Using the ``--skip-covered`` option on an HTML report with 100% coverage
would cause a "No data to report" error, as reported in `issue 549`_. This is
now fixed; thanks, Loรฏc Dachary.
- If-statements can be optimized away during compilation, for example,
``if 0:`` or ``if __debug__:``. Coverage.py had problems properly
understanding these statements which existed in the source, but not in the
compiled bytecode. This problem, reported in `issue 522`_, is now fixed.
- If you specified ``--source`` as a directory, then coverage.py would look for
importable Python files in that directory, and could identify ones that had
never been executed at all. But if you specified it as a package name, that
detection wasn't performed. Now it is, closing `issue 426`_. Thanks to Loรฏc
Dachary for the fix.
- If you started and stopped coverage measurement thousands of times in your
process, you could crash Python with a "Fatal Python error: deallocating
None" error. This is now fixed. Thanks to Alex Groce for the bug report.
- On PyPy, measuring coverage in subprocesses could produce a warning: "Trace
function changed, measurement is likely wrong: None". This was spurious, and
has been suppressed.
- Previously, coverage.py couldn't start on Jython, due to that implementation
missing the multiprocessing module (`issue 551`_). This problem has now been
fixed. Also, `issue 322`_ about not being able to invoke coverage
conveniently, seems much better: ``jython -m coverage run myprog.py`` works
properly.
- Let's say you ran the HTML report over and over again in the same output
directory, with ``--skip-covered``. And imagine due to your heroic
test-writing efforts, a file just achieved the goal of 100% coverage. With
coverage.py 4.3, the old HTML file with the less-than-100% coverage would be
left behind. This file is now properly deleted.

- Some environments couldn't install 4.3, as described in `issue 540`_. This is
now fixed.
- The check for conflicting ``--source`` and ``--include`` was too simple in a
few different ways, breaking a few perfectly reasonable use cases, described
in `issue 541`_. The check has been reverted while we re-think the fix for
`issue 265`_.

Version 4.3 โ 2016-12-27
------------------------
Special thanks to **Loรฏc Dachary**, who took an extraordinary interest in
coverage.py and contributed a number of improvements in this release.
- Subprocesses that are measured with `automatic subprocess measurement`_ used
to read in any pre-existing data file. This meant data would be incorrectly
carried forward from run to run. Now those files are not read, so each
subprocess only writes its own data. Fixes `issue 510`_.
- The ``coverage combine`` command will now fail if there are no data files to
combine. The combine changes in 4.2 meant that multiple combines could lose
data, leaving you with an empty .coverage data file. Fixes
`issue 525`_, `issue 412`_, `issue 516`_, and probably `issue 511`_.
- Coverage.py wouldn't execute `sys.excepthook`_ when an exception happened in
your program. Now it does, thanks to Andrew Hoos. Closes `issue 535`_.
- Branch coverage fixes:
- Branch coverage could misunderstand a finally clause on a try block that
never continued on to the following statement, as described in `issue
493`_. This is now fixed. Thanks to Joe Doherty for the report and Loรฏc
Dachary for the fix.
- A while loop with a constant condition (while True) and a continue
statement would be mis-analyzed, as described in `issue 496`_. This is now
fixed, thanks to a bug report by Eli Skeggs and a fix by Loรฏc Dachary.
- While loops with constant conditions that were never executed could result
in a non-zero coverage report. Artem Dayneko reported this in `issue
502`_, and Loรฏc Dachary provided the fix.
- The HTML report now supports a ``--skip-covered`` option like the other
reporting commands. Thanks, Loรฏc Dachary for the implementation, closing
`issue 433`_.
- Options can now be read from a tox.ini file, if any. Like setup.cfg, sections
are prefixed with "coverage:", so ``[run]`` options will be read from the
``[coverage:run]`` section of tox.ini. Implements part of `issue 519`_.
Thanks, Stephen Finucane.
- Specifying both ``--source`` and ``--include`` no longer silently ignores the
include setting, instead it fails with a message. Thanks, Nathan Land and
Loรฏc Dachary. Closes `issue 265`_.
- The ``Coverage.combine`` method has a new parameter, ``strict=False``, to
support failing if there are no data files to combine.
- When forking subprocesses, the coverage data files would have the same random
number appended to the file name. This didn't cause problems, because the
file names had the process id also, making collisions (nearly) impossible.
But it was disconcerting. This is now fixed.
- The text report now properly sizes headers when skipping some files, fixing
`issue 524`_. Thanks, Anthony Sottile and Loรฏc Dachary.
- Coverage.py can now search .pex files for source, just as it can .zip and
.egg. Thanks, Peter Ebden.
- Data files are now about 15% smaller.
- Improvements in the ``[run] debug`` setting:
- The "dataio" debug setting now also logs when data files are deleted during
combining or erasing.
- A new debug option, "multiproc", for logging the behavior of
``concurrency=multiprocessing``.
- If you used the debug options "config" and "callers" together, you'd get a
call stack printed for every line in the multi-line config output. This is
now fixed.
- Fixed an unusual bug involving multiple coding declarations affecting code
containing code in multi-line strings: `issue 529`_.
- Coverage.py will no longer be misled into thinking that a plain file is a
package when interpreting ``--source`` options. Thanks, Cosimo Lupo.
- If you try to run a non-Python file with coverage.py, you will now get a more
useful error message. `Issue 514`_.
- The default pragma regex changed slightly, but this will only matter to you
if you are deranged and use mixed-case pragmas.
- Deal properly with non-ASCII file names in an ASCII-only world, `issue 533`_.
- Programs that set Unicode configuration values could cause UnicodeErrors when
generating HTML reports. Pytest-cov is one example. This is now fixed.
- Prevented deprecation warnings from configparser that happened in some
circumstances, closing `issue 530`_.
- Corrected the name of the jquery.ba-throttle-debounce.js library. Thanks,
Ben Finney. Closes `issue 505`_.
- Testing against PyPy 5.6 and PyPy3 5.5.
- Switched to pytest from nose for running the coverage.py tests.
- Renamed AUTHORS.txt to CONTRIBUTORS.txt, since there are other ways to
contribute than by writing code. Also put the count of contributors into the
author string in setup.py, though this might be too cute.

Version 4.2 โ 2016-07-26
------------------------
- Since ``concurrency=multiprocessing`` uses subprocesses, options specified on
the coverage.py command line will not be communicated down to them. Only
options in the configuration file will apply to the subprocesses.
Previously, the options didn't apply to the subprocesses, but there was no
indication. Now it is an error to use ``--concurrency=multiprocessing`` and
other run-affecting options on the command line. This prevents
failures like those reported in `issue 495`_.
- Filtering the HTML report is now faster, thanks to Ville Skyttรค.
.. _issue 495: https://github.com/nedbat/coveragepy/issues/495
Version 4.2b1 โ 2016-07-04
--------------------------
Work from the PyCon 2016 Sprints!
- BACKWARD INCOMPATIBILITY: the ``coverage combine`` command now ignores an
existing ``.coverage`` data file. It used to include that file in its
combining. This caused confusing results, and extra tox "clean" steps. If
you want the old behavior, use the new ``coverage combine --append`` option.
- The ``concurrency`` option can now take multiple values, to support programs
using multiprocessing and another library such as eventlet. This is only
possible in the configuration file, not from the command line. The
configuration file is the only way for subprocesses to all run with the same
options. Fixes `issue 484`_. Thanks to Josh Williams for prototyping.
- Using a ``concurrency`` setting of ``multiprocessing`` now implies
``--parallel`` so that the main program is measured similarly to the
subprocesses.
- When using `automatic subprocess measurement`_, running coverage commands
would create spurious data files. This is now fixed, thanks to diagnosis and
testing by Dan Riti. Closes `issue 492`_.
- A new configuration option, ``report:sort``, controls what column of the
text report is used to sort the rows. Thanks to Dan Wandschneider, this
closes `issue 199`_.
- The HTML report has a more-visible indicator for which column is being
sorted. Closes `issue 298`_, thanks to Josh Williams.
- If the HTML report cannot find the source for a file, the message now
suggests using the ``-i`` flag to allow the report to continue. Closes
`issue 231`_, thanks, Nathan Land.
- When reports are ignoring errors, there's now a warning if a file cannot be
parsed, rather than being silently ignored. Closes `issue 396`_. Thanks,
Matthew Boehm.
- A new option for ``coverage debug`` is available: ``coverage debug config``
shows the current configuration. Closes `issue 454`_, thanks to Matthew
Boehm.
- Running coverage as a module (``python -m coverage``) no longer shows the
program name as ``__main__.py``. Fixes `issue 478`_. Thanks, Scott Belden.
- The `test_helpers` module has been moved into a separate pip-installable
package: `unittest-mixins`_.

Version 4.1 โ 2016-05-21
------------------------
- The internal attribute `Reporter.file_reporters` was removed in 4.1b3. It
should have come has no surprise that there were third-party tools out there
using that attribute. It has been restored, but with a deprecation warning.
Version 4.1b3 โ 2016-05-10
--------------------------
- When running your program, execution can jump from an ``except X:`` line to
some other line when an exception other than ``X`` happens. This jump is no
longer considered a branch when measuring branch coverage.
- When measuring branch coverage, ``yield`` statements that were never resumed
were incorrectly marked as missing, as reported in `issue 440`_. This is now
fixed.
- During branch coverage of single-line callables like lambdas and generator
expressions, coverage.py can now distinguish between them never being called,
or being called but not completed. Fixes `issue 90`_, `issue 460`_ and
`issue 475`_.
- The HTML report now has a map of the file along the rightmost edge of the
page, giving an overview of where the missed lines are. Thanks, Dmitry
Shishov.
- The HTML report now uses different monospaced fonts, favoring Consolas over
Courier. Along the way, `issue 472`_ about not properly handling one-space
indents was fixed. The index page also has slightly different styling, to
try to make the clickable detail pages more apparent.
- Missing branches reported with ``coverage report -m`` will now say ``->exit``
for missed branches to the exit of a function, rather than a negative number.
Fixes `issue 469`_.
- ``coverage --help`` and ``coverage --version`` now mention which tracer is
installed, to help diagnose problems. The docs mention which features need
the C extension. (`issue 479`_)
- Officially support PyPy 5.1, which required no changes, just updates to the
docs.
- The `Coverage.report` function had two parameters with non-None defaults,
which have been changed. `show_missing` used to default to True, but now
defaults to None. If you had been calling `Coverage.report` without
specifying `show_missing`, you'll need to explicitly set it to True to keep
the same behavior. `skip_covered` used to default to False. It is now None,
which doesn't change the behavior. This fixes `issue 485`_.
- It's never been possible to pass a namespace module to one of the analysis
functions, but now at least we raise a more specific error message, rather
than getting confused. (`issue 456`_)
- The `coverage.process_startup` function now returns the `Coverage` instance
it creates, as suggested in `issue 481`_.
- Make a small tweak to how we compare threads, to avoid buggy custom
comparison code in thread classes. (`issue 245`_)

Version 4.1b2 โ 2016-01-23
--------------------------
- Problems with the new branch measurement in 4.1 beta 1 were fixed:
- Class docstrings were considered executable. Now they no longer are.
- ``yield from`` and ``await`` were considered returns from functions, since
they could transfer control to the caller. This produced unhelpful
"missing branch" reports in a number of circumstances. Now they no longer
are considered returns.
- In unusual situations, a missing branch to a negative number was reported.
This has been fixed, closing `issue 466`_.
- The XML report now produces correct package names for modules found in
directories specified with ``source=``. Fixes `issue 465`_.
- ``coverage report`` won't produce trailing white space.
.. _issue 465: https://github.com/nedbat/coveragepy/issues/465
.. _issue 466: https://github.com/nedbat/coveragepy/issues/466
Version 4.1b1 โ 2016-01-10
--------------------------
- Branch analysis has been rewritten: it used to be based on bytecode, but now
uses AST analysis. This has changed a number of things:
- More code paths are now considered runnable, especially in
``try``/``except`` structures. This may mean that coverage.py will
identify more code paths as uncovered. This could either raise or lower
your overall coverage number.
- Python 3.5's ``async`` and ``await`` keywords are properly supported,
fixing `issue 434`_.
- Some long-standing branch coverage bugs were fixed:
- `issue 129`_: functions with only a docstring for a body would
incorrectly report a missing branch on the ``def`` line.
- `issue 212`_: code in an ``except`` block could be incorrectly marked as
a missing branch.
- `issue 146`_: context managers (``with`` statements) in a loop or ``try``
block could confuse the branch measurement, reporting incorrect partial
branches.
- `issue 422`_: in Python 3.5, an actual partial branch could be marked as
complete.
- Pragmas to disable coverage measurement can now be used on decorator lines,
and they will apply to the entire function or class being decorated. This
implements the feature requested in `issue 131`_.
- Multiprocessing support is now available on Windows. Thanks, Rodrigue
Cloutier.
- Files with two encoding declarations are properly supported, fixing
`issue 453`_. Thanks, Max Linke.
- Non-ascii characters in regexes in the configuration file worked in 3.7, but
stopped working in 4.0. Now they work again, closing `issue 455`_.
- Form-feed characters would prevent accurate determination of the beginning of
statements in the rest of the file. This is now fixed, closing `issue 461`_.

Version 4.0.3 โ 2015-11-24
--------------------------
- Fixed a mysterious problem that manifested in different ways: sometimes
hanging the process (`issue 420`_), sometimes making database connections
fail (`issue 445`_).
- The XML report now has correct ```` elements when using a
``--source=`` option somewhere besides the current directory. This fixes
`issue 439`_. Thanks, Arcadiy Ivanov.
- Fixed an unusual edge case of detecting source encodings, described in
`issue 443`_.
- Help messages that mention the command to use now properly use the actual
command name, which might be different than "coverage". Thanks to Ben
Finney, this closes `issue 438`_.

--------------------------
- More work on supporting unusually encoded source. Fixed `issue 431`_.
- Files or directories with non-ASCII characters are now handled properly,
fixing `issue 432`_.
- Setting a trace function with sys.settrace was broken by a change in 4.0.1,
as reported in `issue 436`_. This is now fixed.

docs.

Version 4.0.1 โ 2015-10-13
--------------------------
- When combining data files, unreadable files will now generate a warning
instead of failing the command. This is more in line with the older
coverage.py v3.7.1 behavior, which silently ignored unreadable files.
Prompted by `issue 418`_.
- The --skip-covered option would skip reporting on 100% covered files, but
also skipped them when calculating total coverage. This was wrong, it should
only remove lines from the report, not change the final answer. This is now
fixed, closing `issue 423`_.
- In 4.0, the data file recorded a summary of the system on which it was run.
Combined data files would keep all of those summaries. This could lead to
enormous data files consisting of mostly repetitive useless information. That
summary is now gone, fixing `issue 415`_. If you want summary information,
get in touch, and we'll figure out a better way to do it.
- Test suites that mocked os.path.exists would experience strange failures, due
to coverage.py using their mock inadvertently. This is now fixed, closing
`issue 416`_.
- Importing a ``__init__`` module explicitly would lead to an error:
``AttributeError: 'module' object has no attribute '__path__'``, as reported
in `issue 410`_. This is now fixed.
- Code that uses ``sys.settrace(sys.gettrace())`` used to incur a more than 2x
speed penalty. Now there's no penalty at all. Fixes `issue 397`_.
- Pyexpat C code will no longer be recorded as a source file, fixing
`issue 419`_.
- The source kit now contains all of the files needed to have a complete source
tree, re-fixing `issue 137`_ and closing `issue 281`_.

Version 4.0 โ 2015-09-20
------------------------
No changes from 4.0b3
Version 4.0b3 โ 2015-09-07
--------------------------
- Reporting on an unmeasured file would fail with a traceback. This is now
fixed, closing `issue 403`_.
- The Jenkins ShiningPanda_ plugin looks for an obsolete file name to find the
HTML reports to publish, so it was failing under coverage.py 4.0. Now we
create that file if we are running under Jenkins, to keep things working
smoothly. `issue 404`_.
- Kits used to include tests and docs, but didn't install them anywhere, or
provide all of the supporting tools to make them useful. Kits no longer
include tests and docs. If you were using them from the older packages, get
in touch and help me understand how.

Version 4.0b2 โ 2015-08-22
--------------------------
- 4.0b1 broke ``--append`` creating new data files. This is now fixed, closing
`issue 392`_.
- ``py.test --cov`` can write empty data, then touch files due to ``--source``,
which made coverage.py mistakenly force the data file to record lines instead
of arcs. This would lead to a "Can't combine line data with arc data" error
message. This is now fixed, and changed some method names in the
CoverageData interface. Fixes `issue 399`_.
- `CoverageData.read_fileobj` and `CoverageData.write_fileobj` replace the
`.read` and `.write` methods, and are now properly inverses of each other.
- When using ``report --skip-covered``, a message will now be included in the
report output indicating how many files were skipped, and if all files are
skipped, coverage.py won't accidentally scold you for having no data to
report. Thanks, Krystian Kichewko.
- A new conversion utility has been added: ``python -m coverage.pickle2json``
will convert v3.x pickle data files to v4.x JSON data files. Thanks,
Alexander Todorov. Closes `issue 395`_.
- A new version identifier is available, `coverage.version_info`, a plain tuple
of values similar to `sys.version_info`_.

Version 4.0b1 โ 2015-08-02
--------------------------
- Coverage.py is now licensed under the Apache 2.0 license. See NOTICE.txt for
details. Closes `issue 313`_.
- The data storage has been completely revamped. The data file is now
JSON-based instead of a pickle, closing `issue 236`_. The `CoverageData`
class is now a public supported documented API to the data file.
- A new configuration option, ``[run] note``, lets you set a note that will be
stored in the `runs` section of the data file. You can use this to annotate
the data file with any information you like.
- Unrecognized configuration options will now print an error message and stop
coverage.py. This should help prevent configuration mistakes from passing
silently. Finishes `issue 386`_.
- In parallel mode, ``coverage erase`` will now delete all of the data files,
fixing `issue 262`_.
- Coverage.py now accepts a directory name for ``coverage run`` and will run a
``__main__.py`` found there, just like Python will. Fixes `issue 252`_.
Thanks, Dmitry Trofimov.
- The XML report now includes a ``missing-branches`` attribute. Thanks, Steve
Peak. This is not a part of the Cobertura DTD, so the XML report no longer
references the DTD.
- Missing branches in the HTML report now have a bit more information in the
right-hand annotations. Hopefully this will make their meaning clearer.
- All the reporting functions now behave the same if no data had been
collected, exiting with a status code of 1. Fixed ``fail_under`` to be
applied even when the report is empty. Thanks, Ionel Cristian Mฤrieศ.
- Plugins are now initialized differently. Instead of looking for a class
called ``Plugin``, coverage.py looks for a function called ``coverage_init``.
- A file-tracing plugin can now ask to have built-in Python reporting by
returning `"python"` from its `file_reporter()` method.
- Code that was executed with `exec` would be mis-attributed to the file that
called it. This is now fixed, closing `issue 380`_.
- The ability to use item access on `Coverage.config` (introduced in 4.0a2) has
been changed to a more explicit `Coverage.get_option` and
`Coverage.set_option` API.
- The ``Coverage.use_cache`` method is no longer supported.
- The private method ``Coverage._harvest_data`` is now called
``Coverage.get_data``, and returns the ``CoverageData`` containing the
collected data.
- The project is consistently referred to as "coverage.py" throughout the code
and the documentation, closing `issue 275`_.
- Combining data files with an explicit configuration file was broken in 4.0a6,
but now works again, closing `issue 385`_.
- ``coverage combine`` now accepts files as well as directories.
- The speed is back to 3.7.1 levels, after having slowed down due to plugin
support, finishing up `issue 387`_.

Version 4.0a6 โ 2015-06-21
--------------------------
- Python 3.5b2 and PyPy 2.6.0 are supported.
- The original module-level function interface to coverage.py is no longer
supported. You must now create a ``coverage.Coverage`` object, and use
methods on it.
- The ``coverage combine`` command now accepts any number of directories as
arguments, and will combine all the data files from those directories. This
means you don't have to copy the files to one directory before combining.
Thanks, Christine Lytwynec. Finishes `issue 354`_.
- Branch coverage couldn't properly handle certain extremely long files. This
is now fixed (`issue 359`_).
- Branch coverage didn't understand yield statements properly. Mickie Betz
persisted in pursuing this despite Ned's pessimism. Fixes `issue 308`_ and
`issue 324`_.
- The ``COVERAGE_DEBUG`` environment variable can be used to set the
``[run] debug`` configuration option to control what internal operations are
logged.
- HTML reports were truncated at formfeed characters. This is now fixed
(`issue 360`_). It's always fun when the problem is due to a `bug in the
Python standard library `_.
- Files with incorrect encoding declaration comments are no longer ignored by
the reporting commands, fixing `issue 351`_.
- HTML reports now include a time stamp in the footer, closing `issue 299`_.
Thanks, Conrad Ho.
- HTML reports now begrudgingly use double-quotes rather than single quotes,
because there are "software engineers" out there writing tools that read HTML
and somehow have no idea that single quotes exist. Capitulates to the absurd
`issue 361`_. Thanks, Jon Chappell.
- The ``coverage annotate`` command now handles non-ASCII characters properly,
closing `issue 363`_. Thanks, Leonardo Pistone.
- Drive letters on Windows were not normalized correctly, now they are. Thanks,
Ionel Cristian Mฤrieศ.
- Plugin support had some bugs fixed, closing `issue 374`_ and `issue 375`_.

Version 4.0a5 โ 2015-02-16
--------------------------
- Plugin support is now implemented in the C tracer instead of the Python
tracer. This greatly improves the speed of tracing projects using plugins.
- Coverage.py now always adds the current directory to sys.path, so that
plugins can import files in the current directory (`issue 358`_).
- If the `config_file` argument to the Coverage constructor is specified as
".coveragerc", it is treated as if it were True. This means setup.cfg is
also examined, and a missing file is not considered an error (`issue 357`_).
- Wildly experimental: support for measuring processes started by the
multiprocessing module. To use, set ``--concurrency=multiprocessing``,
either on the command line or in the .coveragerc file (`issue 117`_). Thanks,
Eduardo Schettino. Currently, this does not work on Windows.
- A new warning is possible, if a desired file isn't measured because it was
imported before coverage.py was started (`issue 353`_).
- The `coverage.process_startup` function now will start coverage measurement
only once, no matter how many times it is called. This fixes problems due
to unusual virtualenv configurations (`issue 340`_).
- Added 3.5.0a1 to the list of supported CPython versions.

Version 4.0a4 โ 2015-01-25
--------------------------
- Plugins can now provide sys_info for debugging output.
- Started plugins documentation.
- Prepared to move the docs to readthedocs.org.
Version 4.0a3 โ 2015-01-20
--------------------------
- Reports now use file names with extensions. Previously, a report would
describe a/b/c.py as "a/b/c". Now it is shown as "a/b/c.py". This allows
for better support of non-Python files, and also fixed `issue 69`_.
- The XML report now reports each directory as a package again. This was a bad
regression, I apologize. This was reported in `issue 235`_, which is now
fixed.
- A new configuration option for the XML report: ``[xml] package_depth``
controls which directories are identified as packages in the report.
Directories deeper than this depth are not reported as packages.
The default is that all directories are reported as packages.
Thanks, Lex Berezhny.
- When looking for the source for a frame, check if the file exists. On
Windows, .pyw files are no longer recorded as .py files. Along the way, this
fixed `issue 290`_.
- Empty files are now reported as 100% covered in the XML report, not 0%
covered (`issue 345`_).
- Regexes in the configuration file are now compiled as soon as they are read,
to provide error messages earlier (`issue 349`_).

Version 4.0a2 โ 2015-01-14
--------------------------
- Officially support PyPy 2.4, and PyPy3 2.4. Drop support for
CPython 3.2 and older versions of PyPy. The code won't work on CPython 3.2.
It will probably still work on older versions of PyPy, but I'm not testing
against them.
- Plugins!
- The original command line switches (`-x` to run a program, etc) are no
longer supported.
- A new option: `coverage report --skip-covered` will reduce the number of
files reported by skipping files with 100% coverage. Thanks, Krystian
Kichewko. This means that empty `__init__.py` files will be skipped, since
they are 100% covered, closing `issue 315`_.
- You can now specify the ``--fail-under`` option in the ``.coveragerc`` file
as the ``[report] fail_under`` option. This closes `issue 314`_.
- The ``COVERAGE_OPTIONS`` environment variable is no longer supported. It was
a hack for ``--timid`` before configuration files were available.
- The HTML report now has filtering. Type text into the Filter box on the
index page, and only modules with that text in the name will be shown.
Thanks, Danny Allen.
- The textual report and the HTML report used to report partial branches
differently for no good reason. Now the text report's "missing branches"
column is a "partial branches" column so that both reports show the same
numbers. This closes `issue 342`_.
- If you specify a ``--rcfile`` that cannot be read, you will get an error
message. Fixes `issue 343`_.
- The ``--debug`` switch can now be used on any command.
- You can now programmatically adjust the configuration of coverage.py by
setting items on `Coverage.config` after construction.
- A module run with ``-m`` can be used as the argument to ``--source``, fixing
`issue 328`_. Thanks, Buck Evan.
- The regex for matching exclusion pragmas has been fixed to allow more kinds
of white space, fixing `issue 334`_.
- Made some PyPy-specific tweaks to improve speed under PyPy. Thanks, Alex
Gaynor.
- In some cases, with a source file missing a final newline, coverage.py would
count statements incorrectly. This is now fixed, closing `issue 293`_.
- The status.dat file that HTML reports use to avoid re-creating files that
haven't changed is now a JSON file instead of a pickle file. This obviates
`issue 287`_ and `issue 237`_.

Version 4.0a1 โ 2014-09-27
--------------------------
- Python versions supported are now CPython 2.6, 2.7, 3.2, 3.3, and 3.4, and
PyPy 2.2.
- Gevent, eventlet, and greenlet are now supported, closing `issue 149`_.
The ``concurrency`` setting specifies the concurrency library in use. Huge
thanks to Peter Portante for initial implementation, and to Joe Jevnik for
the final insight that completed the work.
- Options are now also read from a setup.cfg file, if any. Sections are
prefixed with "coverage:", so the ``[run]`` options will be read from the
``[coverage:run]`` section of setup.cfg. Finishes `issue 304`_.
- The ``report -m`` command can now show missing branches when reporting on
branch coverage. Thanks, Steve Leonard. Closes `issue 230`_.
- The XML report now contains a element, fixing `issue 94`_. Thanks
Stan Hu.
- The class defined in the coverage module is now called ``Coverage`` instead
of ``coverage``, though the old name still works, for backward compatibility.
- The ``fail-under`` value is now rounded the same as reported results,
preventing paradoxical results, fixing `issue 284`_.
- The XML report will now create the output directory if need be, fixing
`issue 285`_. Thanks, Chris Rose.
- HTML reports no longer raise UnicodeDecodeError if a Python file has
un-decodable characters, fixing `issue 303`_ and `issue 331`_.
- The annotate command will now annotate all files, not just ones relative to
the current directory, fixing `issue 57`_.
- The coverage module no longer causes deprecation warnings on Python 3.4 by
importing the imp module, fixing `issue 305`_.
- Encoding declarations in source files are only considered if they are truly
comments. Thanks, Anthony Sottile.

Version 3.7.1 โ 2013-12-13
--------------------------
- Improved the speed of HTML report generation by about 20%.
- Fixed the mechanism for finding OS-installed static files for the HTML report
so that it will actually find OS-installed static files.
.. _changes_37:
Version 3.7 โ 2013-10-06
------------------------
- Added the ``--debug`` switch to ``coverage run``. It accepts a list of
options indicating the type of internal activity to log to stderr.
- Improved the branch coverage facility, fixing `issue 92`_ and `issue 175`_.
- Running code with ``coverage run -m`` now behaves more like Python does,
setting sys.path properly, which fixes `issue 207`_ and `issue 242`_.
- Coverage.py can now run .pyc files directly, closing `issue 264`_.
- Coverage.py properly supports .pyw files, fixing `issue 261`_.
- Omitting files within a tree specified with the ``source`` option would
cause them to be incorrectly marked as un-executed, as described in
`issue 218`_. This is now fixed.
- When specifying paths to alias together during data combining, you can now
specify relative paths, fixing `issue 267`_.
- Most file paths can now be specified with username expansion (``~/src``, or
``~build/src``, for example), and with environment variable expansion
(``build/$BUILDNUM/src``).
- Trying to create an XML report with no files to report on, would cause a
ZeroDivisionError, but no longer does, fixing `issue 250`_.
- When running a threaded program under the Python tracer, coverage.py no
longer issues a spurious warning about the trace function changing: "Trace
function changed, measurement is likely wrong: None." This fixes `issue
164`_.
- Static files necessary for HTML reports are found in system-installed places,
to ease OS-level packaging of coverage.py. Closes `issue 259`_.
- Source files with encoding declarations, but a blank first line, were not
decoded properly. Now they are. Thanks, Roger Hu.
- The source kit now includes the ``__main__.py`` file in the root coverage
directory, fixing `issue 255`_.

Version 3.6 โ 2013-01-05
------------------------
- Added a page to the docs about troublesome situations, closing `issue 226`_,
and added some info to the TODO file, closing `issue 227`_.
.. _issue 226: https://github.com/nedbat/coveragepy/issues/226
.. _issue 227: https://github.com/nedbat/coveragepy/issues/227
Version 3.6b3 โ 2012-12-29
--------------------------
- Beta 2 broke the nose plugin. It's fixed again, closing `issue 224`_.
.. _issue 224: https://github.com/nedbat/coveragepy/issues/224
Version 3.6b2 โ 2012-12-23
--------------------------
- Coverage.py runs on Python 2.3 and 2.4 again. It was broken in 3.6b1.
- The C extension is optionally compiled using a different more widely-used
technique, taking another stab at fixing `issue 80`_ once and for all.
- Combining data files would create entries for phantom files if used with
``source`` and path aliases. It no longer does.
- ``debug sys`` now shows the configuration file path that was read.
- If an oddly-behaved package claims that code came from an empty-string
file name, coverage.py no longer associates it with the directory name,
fixing `issue 221`_.
.. _issue 221: https://github.com/nedbat/coveragepy/issues/221
Version 3.6b1 โ 2012-11-28
--------------------------
- Wildcards in ``include=`` and ``omit=`` arguments were not handled properly
in reporting functions, though they were when running. Now they are handled
uniformly, closing `issue 143`_ and `issue 163`_. **NOTE**: it is possible
that your configurations may now be incorrect. If you use ``include`` or
``omit`` during reporting, whether on the command line, through the API, or
in a configuration file, please check carefully that you were not relying on
the old broken behavior.
- The **report**, **html**, and **xml** commands now accept a ``--fail-under``
switch that indicates in the exit status whether the coverage percentage was
less than a particular value. Closes `issue 139`_.
- The reporting functions coverage.report(), coverage.html_report(), and
coverage.xml_report() now all return a float, the total percentage covered
measurement.
- The HTML report's title can now be set in the configuration file, with the
``--title`` switch on the command line, or via the API.
- Configuration files now support substitution of environment variables, using
syntax like ``${WORD}``. Closes `issue 97`_.
- Embarrassingly, the ``[xml] output=`` setting in the .coveragerc file simply
didn't work. Now it does.
- The XML report now consistently uses file names for the file name attribute,
rather than sometimes using module names. Fixes `issue 67`_.
Thanks, Marcus Cobden.
- Coverage percentage metrics are now computed slightly differently under
branch coverage. This means that completely un-executed files will now
correctly have 0% coverage, fixing `issue 156`_. This also means that your
total coverage numbers will generally now be lower if you are measuring
branch coverage.
- When installing, now in addition to creating a "coverage" command, two new
aliases are also installed. A "coverage2" or "coverage3" command will be
created, depending on whether you are installing in Python 2.x or 3.x.
A "coverage-X.Y" command will also be created corresponding to your specific
version of Python. Closes `issue 111`_.
- The coverage.py installer no longer tries to bootstrap setuptools or
Distribute. You must have one of them installed first, as `issue 202`_
recommended.
- The coverage.py kit now includes docs (closing `issue 137`_) and tests.
- On Windows, files are now reported in their correct case, fixing `issue 89`_
and `issue 203`_.
- If a file is missing during reporting, the path shown in the error message
is now correct, rather than an incorrect path in the current directory.
Fixes `issue 60`_.
- Running an HTML report in Python 3 in the same directory as an old Python 2
HTML report would fail with a UnicodeDecodeError. This issue (`issue 193`_)
is now fixed.
- Fixed yet another error trying to parse non-Python files as Python, this
time an IndentationError, closing `issue 82`_ for the fourth time...
- If `coverage xml` fails because there is no data to report, it used to
create a zero-length XML file. Now it doesn't, fixing `issue 210`_.
- Jython files now work with the ``--source`` option, fixing `issue 100`_.
- Running coverage.py under a debugger is unlikely to work, but it shouldn't
fail with "TypeError: 'NoneType' object is not iterable". Fixes `issue
201`_.
- On some Linux distributions, when installed with the OS package manager,
coverage.py would report its own code as part of the results. Now it won't,
fixing `issue 214`_, though this will take some time to be repackaged by the
operating systems.
- Docstrings for the legacy singleton methods are more helpful. Thanks Marius
Gedminas. Closes `issue 205`_.
- The pydoc tool can now show documentation for the class `coverage.coverage`.
Closes `issue 206`_.
- Added a page to the docs about contributing to coverage.py, closing
`issue 171`_.
- When coverage.py ended unsuccessfully, it may have reported odd errors like
``'NoneType' object has no attribute 'isabs'``. It no longer does,
so kiss `issue 153`_ goodbye.

Version 3.5.3 โ 2012-09-29
--------------------------
- Line numbers in the HTML report line up better with the source lines, fixing
`issue 197`_, thanks Marius Gedminas.
- When specifying a directory as the source= option, the directory itself no
longer needs to have a ``__init__.py`` file, though its sub-directories do,
to be considered as source files.
- Files encoded as UTF-8 with a BOM are now properly handled, fixing
`issue 179`_. Thanks, Pablo Carballo.
- Fixed more cases of non-Python files being reported as Python source, and
then not being able to parse them as Python. Closes `issue 82`_ (again).
Thanks, Julian Berman.
- Fixed memory leaks under Python 3, thanks, Brett Cannon. Closes `issue 147`_.
- Optimized .pyo files may not have been handled correctly, `issue 195`_.
Thanks, Marius Gedminas.
- Certain unusually named file paths could have been mangled during reporting,
`issue 194`_. Thanks, Marius Gedminas.
- Try to do a better job of the impossible task of detecting when we can't
build the C extension, fixing `issue 183`_.
- Testing is now done with `tox`_, thanks, Marc Abramowitz.

Version 3.5.2 โ 2012-05-04
--------------------------
No changes since 3.5.2.b1
Version 3.5.2b1 โ 2012-04-29
----------------------------
- The HTML report has slightly tweaked controls: the buttons at the top of
the page are color-coded to the source lines they affect.
- Custom CSS can be applied to the HTML report by specifying a CSS file as
the ``extra_css`` configuration value in the ``[html]`` section.
- Source files with custom encodings declared in a comment at the top are now
properly handled during reporting on Python 2. Python 3 always handled them
properly. This fixes `issue 157`_.
- Backup files left behind by editors are no longer collected by the source=
option, fixing `issue 168`_.
- If a file doesn't parse properly as Python, we don't report it as an error
if the file name seems like maybe it wasn't meant to be Python. This is a
pragmatic fix for `issue 82`_.
- The ``-m`` switch on ``coverage report``, which includes missing line numbers
in the summary report, can now be specified as ``show_missing`` in the
config file. Closes `issue 173`_.
- When running a module with ``coverage run -m ``, certain details
of the execution environment weren't the same as for
``python -m ``. This had the unfortunate side-effect of making
``coverage run -m unittest discover`` not work if you had tests in a
directory named "test". This fixes `issue 155`_ and `issue 142`_.
- Now the exit status of your product code is properly used as the process
status when running ``python -m coverage run ...``. Thanks, JT Olds.
- When installing into PyPy, we no longer attempt (and fail) to compile
the C tracer function, closing `issue 166`_.

Version 3.5.1 โ 2011-09-23
--------------------------
- The ``[paths]`` feature unfortunately didn't work in real world situations
where you wanted to, you know, report on the combined data. Now all paths
stored in the combined file are canonicalized properly.
Version 3.5.1b1 โ 2011-08-28
----------------------------
- When combining data files from parallel runs, you can now instruct
coverage.py about which directories are equivalent on different machines. A
``[paths]`` section in the configuration file lists paths that are to be
considered equivalent. Finishes `issue 17`_.
- for-else constructs are understood better, and don't cause erroneous partial
branch warnings. Fixes `issue 122`_.
- Branch coverage for ``with`` statements is improved, fixing `issue 128`_.
- The number of partial branches reported on the HTML summary page was
different than the number reported on the individual file pages. This is
now fixed.
- An explicit include directive to measure files in the Python installation
wouldn't work because of the standard library exclusion. Now the include
directive takes precedence, and the files will be measured. Fixes
`issue 138`_.
- The HTML report now handles Unicode characters in Python source files
properly. This fixes `issue 124`_ and `issue 144`_. Thanks, Devin
Jeanpierre.
- In order to help the core developers measure the test coverage of the
standard library, Brandon Rhodes devised an aggressive hack to trick Python
into running some coverage.py code before anything else in the process.
See the coverage/fullcoverage directory if you are interested.

Version 3.5 โ 2011-06-29
------------------------
- The HTML report hotkeys now behave slightly differently when the current
chunk isn't visible at all: a chunk on the screen will be selected,
instead of the old behavior of jumping to the literal next chunk.
The hotkeys now work in Google Chrome. Thanks, Guido van Rossum.
Version 3.5b1 โ 2011-06-05
--------------------------
- The HTML report now has hotkeys. Try ``n``, ``s``, ``m``, ``x``, ``b``,
``p``, and ``c`` on the overview page to change the column sorting.
On a file page, ``r``, ``m``, ``x``, and ``p`` toggle the run, missing,
excluded, and partial line markings. You can navigate the highlighted
sections of code by using the ``j`` and ``k`` keys for next and previous.
The ``1`` (one) key jumps to the first highlighted section in the file,
and ``0`` (zero) scrolls to the top of the file.
- The ``--omit`` and ``--include`` switches now interpret their values more
usefully. If the value starts with a wildcard character, it is used as-is.
If it does not, it is interpreted relative to the current directory.
Closes `issue 121`_.
- Partial branch warnings can now be pragma'd away. The configuration option
``partial_branches`` is a list of regular expressions. Lines matching any of
those expressions will never be marked as a partial branch. In addition,
there's a built-in list of regular expressions marking statements which
should never be marked as partial. This list includes ``while True:``,
``while 1:``, ``if 1:``, and ``if 0:``.
- The ``coverage()`` constructor accepts single strings for the ``omit=`` and
``include=`` arguments, adapting to a common error in programmatic use.
- Modules can now be run directly using ``coverage run -m modulename``, to
mirror Python's ``-m`` flag. Closes `issue 95`_, thanks, Brandon Rhodes.
- ``coverage run`` didn't emulate Python accurately in one small detail: the
current directory inserted into ``sys.path`` was relative rather than
absolute. This is now fixed.
- HTML reporting is now incremental: a record is kept of the data that
produced the HTML reports, and only files whose data has changed will
be generated. This should make most HTML reporting faster.
- Pathological code execution could disable the trace function behind our
backs, leading to incorrect code measurement. Now if this happens,
coverage.py will issue a warning, at least alerting you to the problem.
Closes `issue 93`_. Thanks to Marius Gedminas for the idea.
- The C-based trace function now behaves properly when saved and restored
with ``sys.gettrace()`` and ``sys.settrace()``. This fixes `issue 125`_
and `issue 123`_. Thanks, Devin Jeanpierre.
- Source files are now opened with Python 3.2's ``tokenize.open()`` where
possible, to get the best handling of Python source files with encodings.
Closes `issue 107`_, thanks, Brett Cannon.
- Syntax errors in supposed Python files can now be ignored during reporting
with the ``-i`` switch just like other source errors. Closes `issue 115`_.
- Installation from source now succeeds on machines without a C compiler,
closing `issue 80`_.
- Coverage.py can now be run directly from a working tree by specifying
the directory name to python: ``python coverage_py_working_dir run ...``.
Thanks, Brett Cannon.
- A little bit of Jython support: `coverage run` can now measure Jython
execution by adapting when $py.class files are traced. Thanks, Adi Roiban.
Jython still doesn't provide the Python libraries needed to make
coverage reporting work, unfortunately.
- Internally, files are now closed explicitly, fixing `issue 104`_. Thanks,
Brett Cannon.

------------------------
- The XML report is now sorted by package name, fixing `issue 88`_.
- Programs that exited with ``sys.exit()`` with no argument weren't handled
properly, producing a coverage.py stack trace. That is now fixed.
.. _issue 88: https://github.com/nedbat/coveragepy/issues/88
Version 3.4b2 โ 2010-09-06
--------------------------
- Completely un-executed files can now be included in coverage results,
reported as 0% covered. This only happens if the --source option is
specified, since coverage.py needs guidance about where to look for source
files.
- The XML report output now properly includes a percentage for branch coverage,
fixing `issue 65`_ and `issue 81`_.
- Coverage percentages are now displayed uniformly across reporting methods.
Previously, different reports could round percentages differently. Also,
percentages are only reported as 0% or 100% if they are truly 0 or 100, and
are rounded otherwise. Fixes `issue 41`_ and `issue 70`_.
- The precision of reported coverage percentages can be set with the
``[report] precision`` config file setting. Completes `issue 16`_.
- Threads derived from ``threading.Thread`` with an overridden `run` method
would report no coverage for the `run` method. This is now fixed, closing
`issue 85`_.

Version 3.4b1 โ 2010-08-21
--------------------------
- BACKWARD INCOMPATIBILITY: the ``--omit`` and ``--include`` switches now take
file patterns rather than file prefixes, closing `issue 34`_ and `issue 36`_.
- BACKWARD INCOMPATIBILITY: the `omit_prefixes` argument is gone throughout
coverage.py, replaced with `omit`, a list of file name patterns suitable for
`fnmatch`. A parallel argument `include` controls what files are included.
- The run command now has a ``--source`` switch, a list of directories or
module names. If provided, coverage.py will only measure execution in those
source files.
- Various warnings are printed to stderr for problems encountered during data
measurement: if a ``--source`` module has no Python source to measure, or is
never encountered at all, or if no data is collected.
- The reporting commands (report, annotate, html, and xml) now have an
``--include`` switch to restrict reporting to modules matching those file
patterns, similar to the existing ``--omit`` switch. Thanks, Zooko.
- The run command now supports ``--include`` and ``--omit`` to control what
modules it measures. This can speed execution and reduce the amount of data
during reporting. Thanks Zooko.
- Since coverage.py 3.1, using the Python trace function has been slower than
it needs to be. A cache of tracing decisions was broken, but has now been
fixed.
- Python 2.7 and 3.2 have introduced new opcodes that are now supported.
- Python files with no statements, for example, empty ``__init__.py`` files,
are now reported as having zero statements instead of one. Fixes `issue 1`_.
- Reports now have a column of missed line counts rather than executed line
counts, since developers should focus on reducing the missed lines to zero,
rather than increasing the executed lines to varying targets. Once
suggested, this seemed blindingly obvious.
- Line numbers in HTML source pages are clickable, linking directly to that
line, which is highlighted on arrival. Added a link back to the index page
at the bottom of each HTML page.
- Programs that call ``os.fork`` will properly collect data from both the child
and parent processes. Use ``coverage run -p`` to get two data files that can
be combined with ``coverage combine``. Fixes `issue 56`_.
- Coverage.py is now runnable as a module: ``python -m coverage``. Thanks,
Brett Cannon.
- When measuring code running in a virtualenv, most of the system library was
being measured when it shouldn't have been. This is now fixed.
- Doctest text files are no longer recorded in the coverage data, since they
can't be reported anyway. Fixes `issue 52`_ and `issue 61`_.
- Jinja HTML templates compile into Python code using the HTML file name,
which confused coverage.py. Now these files are no longer traced, fixing
`issue 82`_.
- Source files can have more than one dot in them (foo.test.py), and will be
treated properly while reporting. Fixes `issue 46`_.
- Source files with DOS line endings are now properly tokenized for syntax
coloring on non-DOS machines. Fixes `issue 53`_.
- Unusual code structure that confused exits from methods with exits from
classes is now properly analyzed. See `issue 62`_.
- Asking for an HTML report with no files now shows a nice error message rather
than a cryptic failure ('int' object is unsubscriptable). Fixes `issue 59`_.

Version 3.3.1 โ 2010-03-06
--------------------------
- Using `parallel=True` in .coveragerc file prevented reporting, but now does
not, fixing `issue 49`_.
- When running your code with "coverage run", if you call `sys.exit()`,
coverage.py will exit with that status code, fixing `issue 50`_.

.. _changes_33:
Version 3.3 โ 2010-02-24
------------------------
- Settings are now read from a .coveragerc file. A specific file can be
specified on the command line with --rcfile=FILE. The name of the file can
be programmatically set with the `config_file` argument to the coverage()
constructor, or reading a config file can be disabled with
`config_file=False`.
- Fixed a problem with nested loops having their branch possibilities
mis-characterized: `issue 39`_.
- Added coverage.process_start to enable coverage measurement when Python
starts.
- Parallel data file names now have a random number appended to them in
addition to the machine name and process id.
- Parallel data files combined with "coverage combine" are deleted after
they're combined, to clean up unneeded files. Fixes `issue 40`_.
- Exceptions thrown from product code run with "coverage run" are now displayed
without internal coverage.py frames, so the output is the same as when the
code is run without coverage.py.
- The `data_suffix` argument to the coverage constructor is now appended with
an added dot rather than simply appended, so that .coveragerc files will not
be confused for data files.
- Python source files that don't end with a newline can now be executed, fixing
`issue 47`_.
- Added an AUTHORS.txt file.

Version 3.2 โ 2009-12-05
------------------------
- Added a ``--version`` option on the command line.
Version 3.2b4 โ 2009-12-01
--------------------------
- Branch coverage improvements:
- The XML report now includes branch information.
- Click-to-sort HTML report columns are now persisted in a cookie. Viewing
a report will sort it first the way you last had a coverage report sorted.
Thanks, `Chris Adams`_.
- On Python 3.x, setuptools has been replaced by `Distribute`_.
.. _Distribute: https://pypi.org/project/distribute/
Version 3.2b3 โ 2009-11-23
--------------------------
- Fixed a memory leak in the C tracer that was introduced in 3.2b1.
- Branch coverage improvements:
- Branches to excluded code are ignored.
- The table of contents in the HTML report is now sortable: click the headers
on any column. Thanks, `Chris Adams`_.
.. _Chris Adams: http://chris.improbable.org
Version 3.2b2 โ 2009-11-19
--------------------------
- Branch coverage improvements:
- Classes are no longer incorrectly marked as branches: `issue 32`_.
- "except" clauses with types are no longer incorrectly marked as branches:
`issue 35`_.
- Fixed some problems syntax coloring sources with line continuations and
source with tabs: `issue 30`_ and `issue 31`_.
- The --omit option now works much better than before, fixing `issue 14`_ and
`issue 33`_. Thanks, Danek Duvall.

Version 3.2b1 โ 2009-11-10
--------------------------
- Branch coverage!
- XML reporting has file paths that let Cobertura find the source code.
- The tracer code has changed, it's a few percent faster.
- Some exceptions reported by the command line interface have been cleaned up
so that tracebacks inside coverage.py aren't shown. Fixes `issue 23`_.
.. _issue 23: https://github.com/nedbat/coveragepy/issues/23

Version 3.1 โ 2009-10-04
------------------------
- Source code can now be read from eggs. Thanks, Ross Lawley. Fixes
`issue 25`_.
.. _issue 25: https://github.com/nedbat/coveragepy/issues/25
Version 3.1b1 โ 2009-09-27
--------------------------
- Python 3.1 is now supported.
- Coverage.py has a new command line syntax with sub-commands. This expands
the possibilities for adding features and options in the future. The old
syntax is still supported. Try "coverage help" to see the new commands.
Thanks to Ben Finney for early help.
- Added an experimental "coverage xml" command for producing coverage reports
in a Cobertura-compatible XML format. Thanks, Bill Hart.
- Added the --timid option to enable a simpler slower trace function that works
for DecoratorTools projects, including TurboGears. Fixed `issue 12`_ and
`issue 13`_.
- HTML reports show modules from other directories. Fixed `issue 11`_.
- HTML reports now display syntax-colored Python source.
- Programs that change directory will still write .coverage files in the
directory where execution started. Fixed `issue 24`_.
- Added a "coverage debug" command for getting diagnostic information about the
coverage.py installation.

.. _changes_301:
Version 3.0.1 โ 2009-07-07
--------------------------
- Removed the recursion limit in the tracer function. Previously, code that
ran more than 500 frames deep would crash. Fixed `issue 9`_.
- Fixed a bizarre problem involving pyexpat, whereby lines following XML parser
invocations could be overlooked. Fixed `issue 10`_.
- On Python 2.3, coverage.py could mis-measure code with exceptions being
raised. This is now fixed.
- The coverage.py code itself will now not be measured by coverage.py, and no
coverage.py modules will be mentioned in the nose --with-cover plug-in.
Fixed `issue 8`_.
- When running source files, coverage.py now opens them in universal newline
mode just like Python does. This lets it run Windows files on Mac, for
example.

.. _changes_30:
Version 3.0 โ 2009-06-13
------------------------
- Fixed the way the Python library was ignored. Too much code was being
excluded the old way.
- Tabs are now properly converted in HTML reports. Previously indentation was
lost. Fixed `issue 6`_.
- Nested modules now get a proper flat_rootname. Thanks, Christian Heimes.
.. _issue 6: https://github.com/nedbat/coveragepy/issues/6
Version 3.0b3 โ 2009-05-16
--------------------------
- Added parameters to coverage.__init__ for options that had been set on the
coverage object itself.
- Added clear_exclude() and get_exclude_list() methods for programmatic
manipulation of the exclude regexes.
- Added coverage.load() to read previously-saved data from the data file.
- Improved the finding of code files. For example, .pyc files that have been
installed after compiling are now located correctly. Thanks, Detlev
Offenbach.
- When using the object API (that is, constructing a coverage() object), data
is no longer saved automatically on process exit. You can re-enable it with
the auto_data=True parameter on the coverage() constructor. The module-level
interface still uses automatic saving.
Version 3.0b2 โ 2009-04-30
--------------------------
HTML reporting, and continued refactoring.
- HTML reports and annotation of source files: use the new -b (browser) switch.
Thanks to George Song for code, inspiration and guidance.
- Code in the Python standard library is not measured by default. If you need
to measure standard library code, use the -L command-line switch during
execution, or the cover_pylib=True argument to the coverage() constructor.
- Source annotation into a directory (-a -d) behaves differently. The
annotated files are named with their hierarchy flattened so that same-named
files from different directories no longer collide. Also, only files in the
current tree are included.
- coverage.annotate_file is no longer available.
- Programs executed with -x now behave more as they should, for example,
__file__ has the correct value.
- .coverage data files have a new pickle-based format designed for better
extensibility.
- Removed the undocumented cache_file argument to coverage.usecache().
Version 3.0b1 โ 2009-03-07
--------------------------
Major overhaul.
- Coverage.py is now a package rather than a module. Functionality has been
split into classes.
- The trace function is implemented in C for speed. Coverage.py runs are now
much faster. Thanks to David Christian for productive micro-sprints and
other encouragement.
- Executable lines are identified by reading the line number tables in the
compiled code, removing a great deal of complicated analysis code.
- Precisely which lines are considered executable has changed in some cases.
Therefore, your coverage stats may also change slightly.
- The singleton coverage object is only created if the module-level functions
are used. This maintains the old interface while allowing better
programmatic use of coverage.py.
- The minimum supported Python version is 2.3.
Version 2.85 โ 2008-09-14
-------------------------
- Add support for finding source files in eggs. Don't check for
morf's being instances of ModuleType, instead use duck typing so that
pseudo-modules can participate. Thanks, Imri Goldberg.
- Use os.realpath as part of the fixing of file names so that symlinks won't
confuse things. Thanks, Patrick Mezard.
Version 2.80 โ 2008-05-25
-------------------------
- Open files in rU mode to avoid line ending craziness. Thanks, Edward Loper.
Version 2.78 โ 2007-09-30
-------------------------
- Don't try to predict whether a file is Python source based on the extension.
Extension-less files are often Pythons scripts. Instead, simply parse the
file and catch the syntax errors. Hat tip to Ben Finney.
Version 2.77 โ 2007-07-29
-------------------------
- Better packaging.
Version 2.76 โ 2007-07-23
-------------------------
- Now Python 2.5 is *really* fully supported: the body of the new with
statement is counted as executable.
Version 2.75 โ 2007-07-22
-------------------------
- Python 2.5 now fully supported. The method of dealing with multi-line
statements is now less sensitive to the exact line that Python reports during
execution. Pass statements are handled specially so that their disappearance
during execution won't throw off the measurement.
Version 2.7 โ 2007-07-21
------------------------
- "#pragma: nocover" is excluded by default.
- Properly ignore docstrings and other constant expressions that appear in the
middle of a function, a problem reported by Tim Leslie.
- coverage.erase() shouldn't clobber the exclude regex. Change how parallel
mode is invoked, and fix erase() so that it erases the cache when called
programmatically.
- In reports, ignore code executed from strings, since we can't do anything
useful with it anyway.
- Better file handling on Linux, thanks Guillaume Chazarain.
- Better shell support on Windows, thanks Noel O'Boyle.
- Python 2.2 support maintained, thanks Catherine Proulx.
- Minor changes to avoid lint warnings.
Version 2.6 โ 2006-08-23
------------------------
- Applied Joseph Tate's patch for function decorators.
- Applied Sigve Tjora and Mark van der Wal's fixes for argument handling.
- Applied Geoff Bache's parallel mode patch.
- Refactorings to improve testability. Fixes to command-line logic for parallel
mode and collect.
Version 2.5 โ 2005-12-04
------------------------
- Call threading.settrace so that all threads are measured. Thanks Martin
Fuzzey.
- Add a file argument to report so that reports can be captured to a different
destination.
- Coverage.py can now measure itself.
- Adapted Greg Rogers' patch for using relative file names, and sorting and
omitting files to report on.
Version 2.2 โ 2004-12-31
------------------------
- Allow for keyword arguments in the module global functions. Thanks, Allen.
Version 2.1 โ 2004-12-14
------------------------
- Return 'analysis' to its original behavior and add 'analysis2'. Add a global
for 'annotate', and factor it, adding 'annotate_file'.
Version 2.0 โ 2004-12-12
------------------------
Significant code changes.
- Finding executable statements has been rewritten so that docstrings and
other quirks of Python execution aren't mistakenly identified as missing
lines.
- Lines can be excluded from consideration, even entire suites of lines.
- The file system cache of covered lines can be disabled programmatically.
- Modernized the code.

Text annotation: ``coverage annotate``
--------------------------------------
.. note::
The **annotate** command has been obsoleted by more modern reporting tools,
including the **html** command. The command is still supported, but won't
be getting new features.
The **annotate** command produces a text annotation of your source code. With
a ``-d`` argument specifying an output directory, each Python file becomes a
text file in that directory. Without ``-d``, the files are written into the
same directories as the original Python files.
Coverage status for each line of source is indicated with a character prefix::
> executed
! missing (not executed)
- excluded
For example::
# A simple function, never called with x==1
> def h(x):
"""Silly function."""
- if 0: # pragma: no cover
- pass
> if x == 1:
! a = 1
> else:
> a = 2
.. [[[cog show_help("annotate") ]]]
.. code::
$ coverage annotate --help
Usage: coverage annotate [options] [modules]
Make annotated copies of the given files, marking statements that are executed
with > and statements that are missed with !.
Options:
-d DIR, --directory=DIR
Write the output files to DIR.
--data-file=INFILE Read coverage data for report generation from this
file. Defaults to '.coverage'. [env: COVERAGE_FILE]
-i, --ignore-errors Ignore errors while reading source files.
--include=PAT1,PAT2,...
Include only files whose paths match one of these
patterns. Accepts shell-style wildcards, which must be
quoted.
--omit=PAT1,PAT2,... Omit files whose paths match one of these patterns.
Accepts shell-style wildcards, which must be quoted.
--debug=OPTS Debug options, separated by commas. [env:
COVERAGE_DEBUG]
-h, --help Get help on this command.
--rcfile=RCFILE Specify configuration file. By default '.coveragerc',
'setup.cfg', 'tox.ini', and 'pyproject.toml' are
tried. [env: COVERAGE_RCFILE]

Combining data files: ``coverage combine``
------------------------------------------
Often test suites are run under different conditions, for example, with
different versions of Python, or dependencies, or on different operating
systems. In these cases, you can collect coverage data for each test run, and
then combine all the separate data files into one combined file for reporting.
The **combine** command reads a number of separate data files, matches the data
by source file name, and writes a combined data file with all of the data.
Coverage normally writes data to a filed named ".coverage". The ``run
--parallel-mode`` switch (or ``[run] parallel=True`` configuration option)
tells coverage to expand the file name to include machine name, process id, and
a random number so that every data file is distinct::
.coverage.Neds-MacBook-Pro.local.88335.316857
.coverage.Geometer.8044.799674
You can also define a new data file name with the ``[run] data_file`` option.
Once you have created a number of these files, you can copy them all to a
single directory, and use the **combine** command to combine them into one
.coverage data file::
$ coverage combine
You can also name directories or files to be combined on the command line::
$ coverage combine data1.dat windows_data_files/
Coverage.py will collect the data from those places and combine them. The
current directory isn't searched if you use command-line arguments. If you
also want data from the current directory, name it explicitly on the command
line.
When coverage.py combines data files, it looks for files named the same as the
data file (defaulting to ".coverage"), with a dotted suffix. Here are some
examples of data files that can be combined::
.coverage.machine1
.coverage.20120807T212300
.coverage.last_good_run.ok
An existing combined data file is ignored and re-written. If you want to use
**combine** to accumulate results into the .coverage data file over a number of
runs, use the ``--append`` switch on the **combine** command. This behavior
was the default before version 4.2.
If any of the data files can't be read, coverage.py will print a warning
indicating the file and the problem.
The original input data files are deleted once they've been combined. If you
want to keep those files, use the ``--keep`` command-line option.
.. [[[cog show_help("combine") ]]]
.. code::
$ coverage combine --help
Usage: coverage combine [options] ...
Combine data from multiple coverage files. The combined results are written to
a single file representing the union of the data. The positional arguments are
data files or directories containing data files. If no paths are provided,
data files in the default data file's directory are combined.
Options:
-a, --append Append data to the data file. Otherwise it starts
clean each time.
--data-file=DATAFILE Base name of the data files to operate on. Defaults to
'.coverage'. [env: COVERAGE_FILE]
--keep Keep original coverage files, otherwise they are
deleted.
-q, --quiet Don't print messages about what is happening.
--debug=OPTS Debug options, separated by commas. [env:
COVERAGE_DEBUG]
-h, --help Get help on this command.
--rcfile=RCFILE Specify configuration file. By default '.coveragerc',

tried. [env: COVERAGE_RCFILE]
.. [[[end]]] (sum: ARyg8KB1fE)
.. _cmd_combine_remapping:
Re-mapping paths
................
To combine data for a source file, coverage has to find its data in each of the
data files. Different test runs may run the same source file from different
locations. For example, different operating systems will use different paths
for the same file, or perhaps each Python version is run from a different
subdirectory. Coverage needs to know that different file paths are actually
the same source file for reporting purposes.
You can tell coverage.py how different source locations relate with a
``[paths]`` section in your configuration file (see :ref:`config_paths`).
It might be more convenient to use the ``[run] relative_files``
setting to store relative file paths (see :ref:`relative_files
`).
If data isn't combining properly, you can see details about the inner workings
with ``--debug=pathmap``.

A few types of information are available:
* ``config``: show coverage's configuration
* ``sys``: show system configuration
* ``data``: show a summary of the collected coverage data
* ``premain``: show the call stack invoking coverage
* ``pybehave``: show internal flags describing Python behavior
* ``sqlite``: show internal compilation options for SQLite
.. [[[cog show_help("debug") ]]]
.. code::

Usage: coverage debug
Display information about the internals of coverage.py, for diagnosing
problems. Topics are: 'data' to show a summary of the collected data; 'sys' to
show installation information; 'config' to show the configuration; 'premain'
to show what is calling coverage; 'pybehave' to show internal flags describing
Python behavior; 'sqlite' to show SQLite compilation options.

``--debug`` option
..................
The ``--debug`` option is available on all commands. It instructs
coverage.py to log internal details of its operation to help with diagnosing
problems. It takes a comma-separated list of options, each indicating a facet
of activity to log:
* ``callers``: annotate each debug message with a stack trace of the callers
to that point.
* ``config``: before starting, dump all the :ref:`configuration `
values.
* ``core``: log decision about choosing the measurement core to use.
* ``dataio``: log when reading or writing any data file.
* ``dataop``: log a summary of data being added to CoverageData objects.
* ``dataop2``: when used with ``debug=dataop``, log the actual data being added
to CoverageData objects.
* ``lock``: log operations acquiring locks in the data layer.
* ``multiproc``: log the start and stop of multiprocessing processes.
* ``patch``: log when patches are applied and when they are executed. See
:ref:`config_run_patch`.
* ``pathmap``: log the remapping of paths that happens during ``coverage
combine``. See :ref:`config_paths`.
* ``pid``: annotate all warnings and debug output with the process and thread
ids.
* ``plugin``: print information about plugin operations.
* ``process``: show process creation information, and changes in the current
directory. This also writes a time stamp and command arguments into the data
file.
* ``pybehave``: show the values of `internal flags `_ describing the
behavior of the current version of Python.
* ``pytest``: indicate the name of the current pytest test when it changes.
* ``self``: annotate each debug message with the object printing the message.
* ``sql``: log the SQL statements used for recording data.
* ``sqldata``: when used with ``debug=sql``, also log the full data being used
in SQL statements.
* ``sys``: before starting, dump all the system and environment information,
as with :ref:`coverage debug sys `.
* ``trace``: print every decision about whether to trace a file or not. For
files not being traced, the reason is also given.

Debug options can also be set with the ``COVERAGE_DEBUG`` environment variable,
a comma-separated list of these options, or in the :ref:`config_run_debug`
section of the .coveragerc file.
The debug output goes to stderr, unless the :ref:`config_run_debug_file`
setting or the ``COVERAGE_DEBUG_FILE`` environment variable names a different
file, which will be appended to. This can be useful because many test runners
capture output, which could hide important details. ``COVERAGE_DEBUG_FILE``
accepts the special names ``stdout`` and ``stderr`` to write to those
destinations.

HTML reporting: ``coverage html``
---------------------------------
Coverage.py can annotate your source code to show which lines were executed
and which were not. The **html** command creates an HTML report similar to the
**report** summary, but as an HTML file. Each module name links to the source
file decorated to show the status of each line.
Here's a `sample report`__.
__ https://nedbatchelder.com/files/sample_coverage_html/index.html
Lines are highlighted: green for executed, red for missing, and gray for
excluded. If you've used branch coverage, partial branches are yellow. The
colored counts at the top of the file are buttons to turn on and off the
highlighting.
A number of keyboard shortcuts are available for navigating the report.
Click the keyboard icon in the upper right to see the complete list.
.. [[[cog show_help("html") ]]]
.. code::
$ coverage html --help
Usage: coverage html [options] [modules]
Create an HTML report of the coverage of the files. Each file gets its own
page, with the source decorated to show executed, excluded, and missed lines.
Options:

Only display data from lines covered in the given
contexts. Accepts Python regexes, which must be
quoted.
-d DIR, --directory=DIR
Write the output files to DIR.
--data-file=INFILE Read coverage data for report generation from this

The title of the report can be set with the ``title`` setting in the
``[html]`` section of the configuration file, or the ``--title`` switch on
the command line.
If you prefer a different style for your HTML report, you can provide your
own CSS file to apply, by specifying a CSS file in the ``[html]`` section of
the configuration file. See :ref:`config_html_extra_css` for details.
The ``-d`` argument specifies an output directory, defaulting to "htmlcov"::
$ coverage html -d coverage_html
Other common reporting options are described above in :ref:`cmd_reporting`.
Generating the HTML report can be time-consuming. Stored with the HTML report
is a data file that is used to speed up reporting the next time. If you
generate a new report into the same directory, coverage.py will skip
generating unchanged pages, making the process faster.
The ``--skip-covered`` switch will skip any file with 100% coverage, letting
you focus on the files that still need attention. The ``--skip-empty`` switch
will skip any file with no executable statements.
The ``--precision`` option controls the number of digits displayed after the
decimal point in coverage percentages, defaulting to none.
If you have :ref:`recorded contexts `, the ``--contexts`` option lets
you choose which contexts to report on, and the ``--show-contexts`` option will
annotate lines with the contexts that ran them. See :ref:`context_reporting`
for details.
These options can also be set in your .coveragerc file. See
:ref:`Configuration: [html] `.

Reporting
---------
Coverage.py provides a few styles of reporting, with the
:ref:`report `,
:ref:`html `,
:ref:`json `,
:ref:`lcov `,
:ref:`xml `,
and :ref:`annotate `
commands. They share a number of common options.
The command-line arguments are module or file names to report on if you'd like
to report on a subset of the data collected.
The ``--include`` and ``--omit`` flags specify lists of file name patterns.
They control which files to report on, and are described in more detail in
:ref:`source`.
The ``-i`` or ``--ignore-errors`` switch tells coverage.py to ignore problems
encountered trying to find source files to report on. This can be useful if
some files are missing, or if your Python execution is tricky enough that file
names are synthesized without real source files.
If you provide a ``--fail-under`` value, the total percentage covered will be
compared to that value. If it is less, the command will exit with a status
code of 2, indicating that the total coverage was less than your target. This
can be used as part of a pass/fail condition, for example in a continuous
integration server. This option isn't available for **annotate**.
These options can also be set in your .coveragerc file. See
:ref:`Configuration: [report] `.

.. _cmd_run:
Execution: ``coverage run``
---------------------------
You collect execution data by running your Python program with the **run**
command::
$ coverage run my_program.py arg1 arg2
blah blah ..your program's output.. blah blah
Your program runs just as if it had been invoked with the Python command line.
Arguments after your file name are passed to your program as usual in
``sys.argv``. Rather than providing a file name, you can use the ``-m`` switch
and specify an importable module name instead, just as you can with the
Python ``-m`` switch::
$ coverage run -m packagename.modulename arg1 arg2
blah blah ..your program's output.. blah blah
.. note::
In most cases, the program to use here is a test runner, not your program
you are trying to measure. The test runner will run your tests and coverage
will measure the coverage of your code along the way.
There are many options:
.. [[[cog show_help("run") ]]]
.. code::
$ coverage run --help
Usage: coverage run [options] [program options]
Run a Python program, measuring code execution.
Options:
-a, --append Append data to the data file. Otherwise it starts
clean each time.
--branch Measure branch coverage in addition to statement
coverage.
--concurrency=LIBS Properly measure code using a concurrency library.
Valid values are: eventlet, gevent, greenlet,
multiprocessing, thread, or a comma-list of them.
--context=LABEL The context label to record for this coverage run.
--data-file=OUTFILE Write the recorded coverage data to this file.
Defaults to '.coverage'. [env: COVERAGE_FILE]
--include=PAT1,PAT2,...
Include only files whose paths match one of these
patterns. Accepts shell-style wildcards, which must be
quoted.
-m, --module is an importable Python module, not a script
path, to be run as 'python -m' would run it.
--omit=PAT1,PAT2,... Omit files whose paths match one of these patterns.
Accepts shell-style wildcards, which must be quoted.
-L, --pylib Measure coverage even inside the Python installed
library, which isn't done by default.
-p, --parallel-mode Append a unique suffix to the data file name to
collect separate data from multiple processes.
--save-signal=SIGNAL Specify a signal that will trigger coverage to write
its collected data. Supported values are: USR1, USR2.
Not available on Windows.
--source=SRC1,SRC2,...
A list of directories or importable names of code to
measure.
--timid Use the slower Python trace function core.
--debug=OPTS Debug options, separated by commas. [env:
COVERAGE_DEBUG]
-h, --help Get help on this command.
--rcfile=RCFILE Specify configuration file. By default '.coveragerc',
'setup.cfg', 'tox.ini', and 'pyproject.toml' are
tried. [env: COVERAGE_RCFILE]
.. [[[end]]] (sum: YwMI03MDmQ)
Many of these options can also be set in the :ref:`config_run` section of your
configuration file. Remember to put options for run after "run", but before
the program invocation::
$ coverage run --source=dir1,dir2 my_program.py arg1 arg2
$ coverage run --source=dir1,dir2 -m packagename.modulename arg1 arg2
If you want :ref:`branch coverage ` measurement, use the ``--branch``
flag. Otherwise only statement coverage is measured.
You can specify the code to measure with the ``--source``, ``--include``, and
``--omit`` switches. See :ref:`Specifying source files ` for
details of their interpretation.
.. note::
Specifying ``--source`` on the ``coverage run`` command line won't affect
subsequent reporting commands like ``coverage xml``. Use the :ref:`source
` setting in the configuration file to apply the setting
uniformly to all commands.
Coverage.py can measure multi-threaded programs by default. If you are using
more other concurrency support, with the `multiprocessing`_, `greenlet`_,
`eventlet`_, or `gevent`_ libraries, then coverage.py can get confused. Use the
``--concurrency`` switch to properly measure programs using these libraries.
Give it a value of ``multiprocessing``, ``thread``, ``greenlet``, ``eventlet``,
or ``gevent``. Values other than ``thread`` require the :ref:`C extension
`.
You can combine multiple values for ``--concurrency``, separated with commas.
You can specify ``thread`` and also one of ``eventlet``, ``gevent``, or
``greenlet``.
If you are using ``--concurrency=multiprocessing``, you must set your other
options in the configuration file. Options on the command line will not be
passed to the processes that multiprocessing creates. Best practice is to use
the configuration file for all options.
.. _multiprocessing: https://docs.python.org/3/library/multiprocessing.html
.. _greenlet: https://greenlet.readthedocs.io/
.. _gevent: https://www.gevent.org/
.. _eventlet: https://eventlet.readthedocs.io/
If you are measuring coverage in a multi-process program, or across a number of
machines, you'll want the ``--parallel-mode`` switch to keep the data separate
during measurement. See :ref:`cmd_combine` below.
You can specify a :ref:`static context ` for a coverage run with
``--context``. This can be any label you want, and will be recorded with the
data. See :ref:`contexts` for more information.
By default, coverage.py does not measure code installed with the Python
interpreter, for example, the standard library. If you want to measure that
code as well as your own, add the ``-L`` (or ``--pylib``) flag.
If your coverage results seem to be overlooking code that you know has been
executed, try running coverage.py again with the ``--timid`` flag. This uses a
simpler but slower trace method, and might be needed in rare cases.
If you are specifying ``--save-signal``, please make sure that your program
doesn't intercept this signal. If it does, coverage won't receive the signal
and the data file will not be written.
.. versionadded:: 7.10 ``--save-signal``
Coverage.py sets an environment variable, ``COVERAGE_RUN`` to indicate that
your code is running under coverage measurement. The value is not relevant,
and may change in the future.
.. _cmd_datafile:
Data file
.........
Coverage.py collects execution data in a file called ".coverage". If need be,
you can set a new file name with the ``COVERAGE_FILE`` environment variable.
This can include a path to another directory.
By default, each run of your program starts with an empty data set. If you need
to run your program multiple times to get complete data (for example, because
you need to supply different options), you can accumulate data across runs with
the ``--append`` flag on the **run** command.

.. _cmd_xml:
XML reporting: ``coverage xml``
-------------------------------
The **xml** command writes coverage data to a "coverage.xml" file in a format
compatible with `Cobertura`_.
.. _Cobertura: http://cobertura.github.io/cobertura/
.. [[[cog show_help("xml") ]]]
.. code::
$ coverage xml --help
Usage: coverage xml [options] [modules]
Generate an XML report of coverage results.
Options:
--data-file=INFILE Read coverage data for report generation from this
file. Defaults to '.coverage'. [env: COVERAGE_FILE]
--fail-under=MIN Exit with a status of 2 if the total coverage is less
than MIN.
-i, --ignore-errors Ignore errors while reading source files.
--include=PAT1,PAT2,...
Include only files whose paths match one of these
patterns. Accepts shell-style wildcards, which must be
quoted.
--omit=PAT1,PAT2,... Omit files whose paths match one of these patterns.
Accepts shell-style wildcards, which must be quoted.
-o OUTFILE Write the XML report to this file. Defaults to
'coverage.xml'
-q, --quiet Don't print messages about what is happening.
--skip-empty Skip files with no code.
--debug=OPTS Debug options, separated by commas. [env:
COVERAGE_DEBUG]
-h, --help Get help on this command.
--rcfile=RCFILE Specify configuration file. By default '.coveragerc',
'setup.cfg', 'tox.ini', and 'pyproject.toml' are
tried. [env: COVERAGE_RCFILE]
.. [[[end]]] (sum: iyOdiVNL4L)
You can specify the name of the output file with the ``-o`` switch.
Other common reporting options are described above in :ref:`cmd_reporting`.
To include complete file paths in the output file, rather than just
the file name, use [include] vs [source] in your ".coveragerc" file.
For example, use this:
.. code:: ini
[run]
include =
foo/*
bar/*
which will result in
.. code:: xml
in place of this:
.. code:: ini
[run]
source =
foo
bar
which may result in
.. code:: xml
These options can also be set in your .coveragerc file. See
:ref:`Configuration: [xml] `.

Commands
========
.. highlight:: console
When you install coverage.py, a command-line script called ``coverage`` is
placed on your path. To help with multi-version installs, it will also create
a ``coverage3`` alias, and a ``coverage-X.Y`` alias, depending on the version
of Python you're using. For example, when installing on Python 3.10, you will
be able to use ``coverage``, ``coverage3``, or ``coverage-3.10`` on the command
line.
Coverage.py has a number of commands:
* **run** -- :ref:`Run a Python program and collect execution data `.
* **combine** -- :ref:`Combine together a number of data files `.
* **erase** -- :ref:`Erase previously collected coverage data `.
* **report** -- :ref:`Report coverage results `.
* **html** --
:ref:`Produce annotated HTML listings with coverage results `.
* **xml** -- :ref:`Produce an XML report with coverage results `.
* **json** -- :ref:`Produce a JSON report with coverage results `.
* **lcov** -- :ref:`Produce an LCOV report with coverage results `.
* **annotate** --
:ref:`Annotate source files with coverage results `.
* **debug** -- :ref:`Get diagnostic information `.
Global options
--------------
Help is available with the **help** command, or with the ``--help`` switch on
any other command::
$ coverage help
$ coverage help run
$ coverage run --help
Version information for coverage.py can be displayed with
``coverage --version``:
.. parsed-literal::
$ coverage --version
Coverage.py, version |release| with C extension
Documentation at |doc-url|
Any command can use a configuration file by specifying it with the
``--rcfile=FILE`` command-line switch. Any option you can set on the command
line can also be set in the configuration file. This can be a better way to
control coverage.py since the configuration file can be checked into source
control, and can provide options that other invocation techniques (like test
runner plugins) may not offer. See :ref:`config` for more details.
For diagnosing problems, commands accept a ``--debug`` option. See
:ref:`cmd_run_debug`.

=======================
Configuration reference
=======================
.. highlight:: ini
Coverage.py options can be specified in a configuration file. This makes it
easier to re-run coverage.py with consistent settings, and also allows for
specification of options that are otherwise only available in the
:ref:`API `.
Configuration files also make it easier to get coverage testing of spawned
subprocesses. See :ref:`subprocess` for more details.
The default name for the configuration file is ``.coveragerc``, in the same
directory coverage.py is being run in. Most of the settings in the
configuration file are tied to your source code and how it should be measured,
so it should be stored with your source, and checked into source control,
rather than put in your home directory.
A different location for the configuration file can be specified with the
``--rcfile=FILE`` command line option or with the ``COVERAGE_RCFILE``
environment variable.
If ``.coveragerc`` doesn't exist and another file hasn't been specified, then
coverage.py will look for settings in other common configuration files, in this
order: setup.cfg, tox.ini, or pyproject.toml. The first file found with
coverage.py settings will be used and other files won't be consulted.
Coverage.py will read from "pyproject.toml" if TOML support is available,
either because you are running on Python 3.11 or later, or because you
installed with the ``toml`` extra (``pip install coverage[toml]``).
Syntax
------
The specific syntax of a configuration file depends on what type it is.
All configuration files are assumed to be in INI format, unless their file
extension is .toml, which are TOML.
INI Syntax
..........
A coverage.py configuration file is in classic .ini file format: sections are
introduced by a ``[section]`` header, and contain ``name = value`` entries.
Lines beginning with ``#`` or ``;`` are ignored as comments.
Strings don't need quotes. Multi-valued strings can be created by indenting
values on multiple lines.
Boolean values can be specified as ``on``, ``off``, ``true``, ``false``, ``1``,
or ``0`` and are case-insensitive.
In setup.cfg or tox.ini, the section names have "coverage:" prefixed, so the
``[run]`` options described below will be found in the ``[coverage:run]``
section of the file.
TOML Syntax
...........
`TOML syntax`_ uses explicit lists with brackets, and strings with quotes.
Booleans are ``true`` or ``false``.
Configuration must be within the ``[tool.coverage]`` section, for example,
``[tool.coverage.run]``. Environment variable expansion in values is
available, but only within quoted strings, even for non-string values.
.. _TOML syntax: https://toml.io
Environment variables
.....................
Environment variables can be substituted in by using dollar signs: ``$WORD``
or ``${WORD}`` will be replaced with the value of ``WORD`` in the environment.
A dollar sign can be inserted with ``$$``. Special forms can be used to
control what happens if the variable isn't defined in the environment:
- If you want to raise an error if an environment variable is undefined, use a
question mark suffix: ``${WORD?}``.
- If you want to provide a default for missing variables, use a dash with a
default value: ``${WORD-default value}``.
- Otherwise, missing environment variables will result in empty strings with no
error.

The specific configuration settings are described below. Many sections and
settings correspond roughly to commands and options in the :ref:`command-line
interface `.
.. _config_run:
[run]
-----
These settings are generally used when running product code, though some apply
to more than one command.
.. _config_run_branch:
[run] branch
............
(boolean, default False) Whether to measure :ref:`branch coverage ` in
addition to statement coverage.
.. _config_run_command_line:
[run] command_line
..................
(string) The command-line to run your program. This will be used if you run
``coverage run`` with no further arguments. Coverage.py options cannot be
specified here, other than ``-m`` to indicate the module to run.
.. versionadded:: 5.0
.. _config_run_concurrency:
[run] concurrency
.................
(multi-string, default "thread") The concurrency libraries in use by the
product code. If your program uses `multiprocessing`_, `gevent`_, `greenlet`_,
or `eventlet`_, you must name that library in this option, or coverage.py will
produce very wrong results.
.. _multiprocessing: https://docs.python.org/3/library/multiprocessing.html
.. _greenlet: https://greenlet.readthedocs.io/
.. _gevent: https://www.gevent.org/
.. _eventlet: https://eventlet.readthedocs.io/
See :ref:`subprocess` for details of multi-process measurement.
Before version 4.2, this option only accepted a single string.
.. versionadded:: 4.0
.. _config_run_context:
[run] context
.............
(string) The static context to record for this coverage run. See
:ref:`contexts` for more information
.. versionadded:: 5.0
.. _config_run_core:
[run] core
..........
(string, default depends on the Python version) Specify which measurement core
to use. Valid values are:
- ``ctrace``: the C implementation of a sys.settrace function. This was the
default until Python 3.13.
- ``sysmon``: the :mod:`sys.monitoring ` implementation.
Only available in Python 3.12+, and the default in Python 3.14+. The sysmon
core does not yet support plugins, dynamic contexts, or some concurrency
libraries. In Python 3.12 and 3.13, it does not support branch coverage.
- ``pytrace``: the pure Python implementation of a sys.settrace function.
This setting was previously only available as the COVERAGE_CORE environment
variable.
.. versionadded:: 7.9
.. _config_run_cover_pylib:
[run] cover_pylib
.................
(boolean, default False) Whether to measure the Python standard library.
.. _config_run_data_file:
[run] data_file
...............
(string, default ".coverage") The name of the data file to use for storing or
reporting coverage. This value can include a path to another directory.
.. _config_run_disable_warnings:
[run] disable_warnings
......................
(multi-string) A list of warnings to disable. Warnings that can be disabled
include a short string at the end, the name of the warning. See
:ref:`cmd_warnings` for specific warnings.
.. _config_run_debug:
[run] debug
...........
(multi-string) A list of debug options. See :ref:`the run --debug option
` for details.
.. _config_run_debug_file:
[run] debug_file
................
(string) A file name to write debug output to. See :ref:`the run --debug
option ` for details.
.. _config_run_dynamic_context:
[run] dynamic_context
.....................
(string) The name of a strategy for setting the dynamic context during
execution. See :ref:`dynamic_contexts` for details.
.. _config_run_include:
[run] include
.............
(multi-string) A list of file name patterns, the files to include in
measurement or reporting. Ignored if ``source`` is set. See :ref:`source` for
details.
.. _config_run_omit:
[run] omit
..........
(multi-string) A list of file name patterns, the files to leave out of
measurement or reporting. See :ref:`source` for details.
.. _config_run_parallel:
[run] parallel
..............
(boolean, default False) Append the machine name, process id and random number
to the data file name to simplify collecting data from many processes. See
:ref:`cmd_combine` for more information.
.. _config_run_patch:
[run] patch
...........
(multi-string) A list of patch names that coverage can apply to the runtime
environment to improve coverage measurement. The available patches correspond
to Python features that could interfere with coverage. The patch inserts
coverage-specific code to collect the correct data.
These must be requested in the configuration instead of being applied
automatically because they could be invasive and produce undesirable
side-effects.
Available patches:
- ``execv``: The :func:`execv ` family of functions end the
current program without giving coverage a chance to write collected data.
This patch adjusts those functions to save the data before starting the next
executable. Not available on Windows.
- ``_exit``: The :func:`os._exit() ` function exits the
process immediately without calling cleanup handlers. This patch saves
coverage data before exiting.
- ``fork``: Forking a process normally continues measuring coverage properly.
This patch stops the previous coverage and starts a new one in the child
process for those times when the default handling isn't enough.
- ``subprocess``: Python sub-processes normally won't get coverage measurement.
This patch configures Python to start coverage automatically, and will apply
to processes created with :mod:`subprocess`, :func:`os.system`, or one of the
:func:`execv ` or :func:`spawnv ` family
of functions. If an ``exec*e`` or ``spawn*e`` function is used, the new
environment must copy over the ``COVERAGE_PROCESS_START`` environment
variable.
The ``subprocess`` patch sets :ref:`parallel = True `
and will require combining data files before reporting. See
:ref:`cmd_combine` for more details.
.. versionadded:: 7.10
.. _config_run_plugins:
[run] plugins
.............
(multi-string) A list of plugin package names. See :ref:`plugins` for more
information.
.. _config_run_relative_files:
[run] relative_files
....................
(boolean, default False) store relative file paths in the data file. This
makes it easier to measure code in one (or multiple) environments, and then
report in another. See :ref:`cmd_combine` for details.
Note that setting ``source`` has to be done in the configuration file rather
than the command line for this option to work, since the reporting commands
need to know the source origin.
.. versionadded:: 5.0
.. _config_run_sigterm:
[run] sigterm
.............
(boolean, default False) if true, register a SIGTERM signal handler to capture
data when the process ends due to a SIGTERM signal. This includes
:meth:`Process.terminate ` and other
ways to terminate a process. This can help when collecting data in usual
situations, but can also introduce problems (see `issue 1310`_).
The signal handler is only registered on Linux and Mac. On Windows, this
setting has no effect.
.. _issue 1310: https://github.com/nedbat/coveragepy/issues/1310
.. versionadded:: 6.4 (in 6.3 this was always enabled)
.. _config_run_source:
[run] source
............
(multi-string) A list of packages or directories, the source to measure during
execution. If set, ``include`` is ignored. See :ref:`source` for details.
.. _config_run_source_pkgs:
[run] source_pkgs
.................
(multi-string) A list of packages, the source to measure during execution.
Operates the same as ``source``, but only names packages, for resolving
ambiguities between packages and directories.
.. versionadded:: 5.3
.. _config_run_source_dirs:
[run] source_dirs
.................
(multi-string) A list of directories, the source to measure during execution.
Operates the same as ``source``, but only names directories, for resolving
ambiguities between packages and directories.
.. versionadded:: 7.8
.. _config_run_timid:
[run] timid
...........
(boolean, default False) Use a simpler but slower trace method. This uses the
PyTracer trace function core instead of CTracer, and is only needed in very
unusual circumstances.
.. _config_paths:
[paths]
-------
The entries in this section are lists of file paths that should be considered
equivalent when combining data from different machines:
.. [[[cog
show_configs(
ini=r"""
[paths]
source =
src/
/jenkins/build/*/src
c:\myproj\src
""",
toml=r"""
[tool.coverage.paths]
source = [
"src/",
"/jenkins/build/*/src",
"c:\\myproj\\src",
]
""",
)
.. ]]]
.. tabs::
.. code-tab:: ini
:caption: .coveragerc
[paths]
source =
src/
/jenkins/build/*/src
c:\myproj\src
.. code-tab:: toml
:caption: pyproject.toml
[tool.coverage.paths]
source = [
"src/",
"/jenkins/build/*/src",

]
.. code-tab:: ini
:caption: setup.cfg or tox.ini
[coverage:paths]
source =
src/
/jenkins/build/*/src
c:\myproj\src
.. [[[end]]] (sum: oHSl8SGiMT)
The names of the entries ("source" in this example) are ignored, you may choose
any name that you like. The value is a list of strings. When combining data
with the ``combine`` command, two file paths will be combined if they start
with paths from the same list.
The first value must be an actual file path on the machine where the reporting
will happen, so that source code can be found. The other values can be file
patterns to match against the paths of collected data, or they can be absolute
or relative file paths on the current machine.
In this example, data collected for "/jenkins/build/1234/src/module.py" will be
combined with data for "c:\\myproj\\src\\module.py", and will be reported
against the source file found at "src/module.py".
If you specify more than one list of paths, they will be considered in order.
A file path will only be remapped if the result exists. If a path matches a
list, but the result doesn't exist, the next list will be tried. The first
list that has an existing result will be used.
Remapping will also be done during reporting, but only within the single data
file being reported. Combining multiple files requires the ``combine``
command.
The ``--debug=pathmap`` option can be used to log details of the re-mapping of
paths. See :ref:`the --debug option `.
See :ref:`cmd_combine_remapping` and :ref:`source_glob` for more information.
.. _config_report:
[report]
--------
Settings common to many kinds of reporting.
.. _config_report_exclude_also:
[report] exclude_also
.....................
(multi-string) A list of regular expressions. This setting is similar to
:ref:`config_report_exclude_lines`: it specifies patterns for lines to exclude
from reporting. This setting is preferred, because it will preserve the
default exclude patterns like ``pragma: no cover`` instead of overwriting them.
See :ref:`config_report_exclude_lines` for further details.
.. versionadded:: 7.2.0
.. _config_report_exclude_lines:
[report] exclude_lines
......................
(multi-string) A list of regular expressions. Any line of your source code
containing a match for one of these regexes is excluded from being reported as
missing. More details are in :ref:`excluding`. If you use this option, you
are replacing all the exclude regexes, so you'll need to also supply the
"pragma: no cover" regex if you still want to use it. The
:ref:`config_report_exclude_also` setting can be used to specify patterns
without overwriting the default set.
You can exclude lines introducing blocks, and the entire block is excluded. If
you exclude a ``def`` line or decorator line, the entire function is excluded.
Be careful when writing this setting: the values are regular expressions that
only have to match a portion of the line. For example, if you write ``...``,
you'll exclude any line with three or more of any character. If you write
``pass``, you'll also exclude the line ``my_pass="foo"``, and so on.
All of the regexes here and in :ref:`config_report_exclude_also` are combined
into one regex for processing, so you cannot use global flags like ``(?s)`` in
your regexes. Use the scoped flag form instead: ``(?s:...)``
.. _config_report_fail_under:
[report] fail_under
...................
(float) A target coverage percentage. If the total coverage measurement is
under this value, then exit with a status code of 2. If you specify a
non-integral value, you must also set ``[report] precision`` properly to make
use of the decimal places. A setting of 100 will fail any value under 100,
regardless of the number of decimal places of precision.
.. _config_report_format:
[report] format
...............
(string, default "text") The format to use for the textual report. The default
is "text" which produces a simple textual table. You can use "markdown" to
produce a Markdown table, or "total" to output only the total coverage
percentage.
.. versionadded:: 7.0
.. _config_report_ignore_errors:
[report] ignore_errors
......................
(boolean, default False) Ignore source code that can't be found, emitting a
warning instead of an exception.
.. _config_report_include:
[report] include
................
(multi-string) A list of file name patterns, the files to include in reporting.
See :ref:`source` for details.
.. _config_include_namespace_packages:
[report] include_namespace_packages
...................................
(boolean, default False) When searching for completely un-executed files,
include directories without ``__init__.py`` files. These are `implicit
namespace packages`_, and are usually skipped.
.. _implicit namespace packages: https://peps.python.org/pep-0420/
.. versionadded:: 7.0
.. _config_report_omit:
[report] omit
.............
(multi-string) A list of file name patterns, the files to leave out of
reporting. See :ref:`source` for details.
.. _config_report_partial_also:
[report] partial_also
.....................
(multi-string) A list of regular expressions. This setting is similar to
:ref:`config_report_partial_branches`: it specifies patterns for branches to
consider fully covered even if they don't exercise both destinations. This
setting is preferred, because it will preserve the default exclude patterns
like ``pragma: no branch`` instead of overwriting them.
See :ref:`config_report_partial_branches` for further details.
.. versionadded:: 7.10.0
.. _config_report_partial_branches:
[report] partial_branches
.........................
(multi-string) A list of regular expressions. Any line of code that matches
one of these regexes is excused from being reported as a partial branch. More
details are in :ref:`branch`. If you use this option, you are replacing all
the partial branch regexes so you'll need to also supply the "pragma: no
branch" regex if you still want to use it. The
:ref:`config_report_partial_also` setting can be used to specify patterns
without overwriting the default set.
.. _config_report_precision:
[report] precision
..................
(integer) The number of digits after the decimal point to display for reported
coverage percentages. The default is 0, displaying for example "87%". A value
of 2 will display percentages like "87.32%". This setting also affects the
interpretation of the ``fail_under`` setting.
.. _config_report_show_missing:
[report] show_missing
.....................
(boolean, default False) When running a summary report, show missing lines.
See :ref:`cmd_report` for more information.
.. _config_report_skip_covered:
[report] skip_covered
.....................
(boolean, default False) Don't report files that are 100% covered. This helps
you focus on files that need attention.
.. _config_report_skip_empty:
[report] skip_empty
...................
(boolean, default False) Don't report files that have no executable code (such
as ``__init__.py`` files).
.. _config_report_sort:
[report] sort
.............
(string, default "Name") Sort the text report by the named column. Allowed
values are "Name", "Stmts", "Miss", "Branch", "BrPart", or "Cover". Prefix
with ``-`` for descending sort (for example, "-cover").
.. _config_html:
[html]
------
Settings particular to HTML reporting. The settings in the ``[report]``
section also apply to HTML output, where appropriate.
.. _config_html_directory:
[html] directory
................
(string, default "htmlcov") Where to write the HTML report files.
.. _config_html_extra_css:
[html] extra_css
................
(string) The path to a file of CSS to apply to the HTML report. The file will
be copied into the HTML output directory. Don't name it "style.css". This CSS
is in addition to the CSS normally used, though you can overwrite as many of
the rules as you like.
.. _config_html_show_context:
[html] show_contexts
....................
(boolean) Should the HTML report include an indication on each line of which
contexts executed the line. See :ref:`dynamic_contexts` for details.
.. _config_html_skip_covered:
[html] skip_covered
...................
(boolean, defaulted from ``[report] skip_covered``) Don't include files in the
report that are 100% covered files. See :ref:`cmd_report` for more information.
.. versionadded:: 5.4
.. _config_html_skip_empty:
[html] skip_empty
.................
(boolean, defaulted from ``[report] skip_empty``) Don't include empty files
(those that have 0 statements) in the report. See :ref:`cmd_report` for more
information.
.. versionadded:: 5.4
.. _config_html_title:
[html] title
............
(string, default "Coverage report") The title to use for the report.
Note this is text, not HTML.
.. _config_xml:
[xml]
-----
Settings particular to XML reporting. The settings in the ``[report]`` section
also apply to XML output, where appropriate.
.. _config_xml_output:
[xml] output
............
(string, default "coverage.xml") Where to write the XML report.
.. _config_xml_package_depth:
[xml] package_depth
...................
(integer, default 99) Controls which directories are identified as packages in
the report. Directories deeper than this depth are not reported as packages.
The default is that all directories are reported as packages.
.. _config_json:
[json]
------
Settings particular to JSON reporting. The settings in the ``[report]``
section also apply to JSON output, where appropriate.
.. versionadded:: 5.0
.. _config_json_output:
[json] output
.............
(string, default "coverage.json") Where to write the JSON file.
.. _config_json_pretty_print:
[json] pretty_print
...................
(boolean, default false) Controls if the JSON is outputted with white space
formatted for human consumption (True) or for minimum file size (False).
.. _config_json_show_contexts:
[json] show_contexts
....................
(boolean, default false) Should the JSON report include an indication of which
contexts executed each line. See :ref:`dynamic_contexts` for details.
.. _config_lcov:
[lcov]
------
Settings particular to LCOV reporting (see :ref:`cmd_lcov`).
.. versionadded:: 6.3
.. _config_lcov_output:
[lcov] output
.............
(string, default "coverage.lcov") Where to write the LCOV file.
.. _config_lcov_line_checksums:
[lcov] line_checksums
.....................
(boolean, default false) Whether to write per-line checksums as part of the
lcov file. Because these checksums cover only lines with actual code on
them, and do not verify the ordering of lines, they provide only a weak
assurance that the source code available to analysis tools (e.g. ``genhtml``)
matches the code that was used to generate the coverage data.

.. _contexts:
====================
Measurement contexts
====================
.. versionadded:: 5.0
Coverage.py measures whether code was run, but it can also record the context
in which it was run. This can provide more information to help you understand
the behavior of your tests.
There are two kinds of context: static and dynamic. Static contexts are fixed
for an entire run, and are set explicitly with an option. Dynamic contexts
change over the course of a single run.
.. _static_contexts:
Static contexts
---------------
A static context is set by an option when you run coverage.py. The value is
fixed for the duration of a run. They can be any text you like, for example,
"python3" or "with_numpy". The context is recorded with the data.
When you :ref:`combine multiple data files ` together, they can
have differing contexts. All of the information is retained, so that the
different contexts are correctly recorded in the combined file.
A static context is specified with the ``--context=CONTEXT`` option to
:ref:`the coverage run command `, or the ``[run] context`` setting in
the configuration file.
.. _dynamic_contexts:
Dynamic contexts
----------------
Dynamic contexts are found during execution. They are most commonly used to
answer the question "what test ran this line?," but have been generalized to
allow any kind of context tracking. As execution proceeds, the dynamic context
changes to record the context of execution. Separate data is recorded for each
context, so that it can be analyzed later.
There are three ways to enable dynamic contexts:
* you can set the ``[run] dynamic_context`` option in your .coveragerc file, or
* you can enable a :ref:`dynamic context switcher `
plugin, or
* another tool (such as a test runner) can call the
:meth:`.Coverage.switch_context` method to set the context explicitly.
The pytest plugin `pytest-cov`_ has a ``--cov-context`` option that uses this
to set the dynamic context for each test.
.. _pytest-cov: https://pypi.org/project/pytest-cov/
.. highlight:: ini
The ``[run] dynamic_context`` setting has only one option now. Set it to
``test_function`` to start a new dynamic context for every test function:
.. [[[cog
show_configs(
ini=r"""
[run]
dynamic_context = test_function
""",
toml=r"""
[tool.coverage.run]
dynamic_context = "test_function"
""",
)
.. ]]]
.. tabs::
.. code-tab:: ini
:caption: .coveragerc
[run]
dynamic_context = test_function
.. code-tab:: toml
:caption: pyproject.toml
[tool.coverage.run]
dynamic_context = "test_function"
.. code-tab:: ini
:caption: setup.cfg or tox.ini
[coverage:run]
dynamic_context = test_function
.. [[[end]]] (sum: dZTDYjHw71)
Each test function you run will be considered a separate dynamic context, and
coverage data will be segregated for each. A test function is any function
whose name starts with "test".
If you have both a static context and a dynamic context, they are joined with a
pipe symbol to be recorded as a single string.
Initially, when your program starts running, the dynamic context is an empty
string. Any code measured before a dynamic context is set will be recorded in
this empty context. For example, if you are recording test names as contexts,
then the code run by the test runner before (and between) tests will be in the
empty context.
Dynamic contexts can be explicitly disabled by setting ``dynamic_context`` to
``none``.
.. _context_reporting:
Context reporting
-----------------
The ``coverage report`` and ``coverage html`` commands both accept
``--contexts`` option, a comma-separated list of regular expressions. The
report will be limited to the contexts that match one of those patterns.
The ``coverage html`` command also has ``--show-contexts``. If set, the HTML
report will include an annotation on each covered line indicating the number of
contexts that executed the line. Clicking the annotation displays a list of
the contexts.
Raw data

For more advanced reporting or analysis, the .coverage data file is a SQLite

Contributing to coverage.py
===========================
.. highlight:: console
I welcome contributions to coverage.py. Over the years, hundreds of people
have provided contributions of various sizes to add features, fix bugs, or just
help diagnose thorny issues. This page should have all the information you
need to make a contribution.
One source of history or ideas are the `bug reports`_ against coverage.py.
There you can find ideas for requested features, or the remains of rejected
ideas.
.. _bug reports: https://github.com/nedbat/coveragepy/issues
Before you begin
----------------
If you have an idea for coverage.py, run it by me before you begin writing
code. This way, I can get you going in the right direction, or point you to
previous work in the area. Things are not always as straightforward as they
seem, and having the benefit of lessons learned by those before you can save
you frustration.
We have a `#coverage channel in the Python Discord `_ that can be a
good place to explore ideas, get help, or help people with coverage.py.
`Join us `_!

Getting the code
----------------
.. PYVERSIONS (mention of lowest version in the "create virtualenv" step).
The coverage.py code is hosted on a GitHub repository at
https://github.com/nedbat/coveragepy. To get a working environment, follow
these steps:
#. `Fork the repo`_ into your own GitHub account. The coverage.py code will
then be copied into a GitHub repository at
``https://github.com/GITHUB_USER/coveragepy`` where GITHUB_USER is your
GitHub username.
#. (Optional) Create a virtualenv to work in, and activate it. There
are a number of ways to do this. Use the method you are comfortable with.
Ideally, use Python 3.10 (the lowest version coverage.py supports).
#. Clone the repository::
$ git clone https://github.com/GITHUB_USER/coveragepy
$ cd coveragepy
#. Install the requirements with either of these commands::
$ make install
$ python3 -m pip install -r requirements/dev.pip
Note: You may need to upgrade pip to install the requirements.
Running the tests
-----------------
.. To get the test output:
# Use the lowest of the PYVERSIONS
# Resize terminal width to 95
% make sterile
.. with COVERAGE_ONE_CORE=
The tests are written mostly as standard unittest-style tests, and are run with
pytest running under `tox`_::

Tox runs the complete test suite a few times for each version of Python you
have installed. The first run uses the C implementation of the trace function,
the second uses the Python implementation. If `sys.monitoring`_ is available,
the suite will be run again with that core.
To limit tox to just a few versions of Python, use the ``-e`` switch::
$ python3 -m tox -e py38,py39
On the tox command line, options after ``--`` are passed to pytest. To run
just a few tests, you can use `pytest test selectors`_::
$ python3 -m tox -- tests/test_misc.py
$ python3 -m tox -- tests/test_misc.py::HasherTest
$ python3 -m tox -- tests/test_misc.py::HasherTest::test_string_hashing
.. with COVERAGE_ONE_CORE=1
These commands run the tests in one file, one class, and just one test,
respectively. The pytest ``-k`` option selects tests based on a word in their
name, which can be very convenient for ad-hoc test selection. Of course you
can combine tox and pytest options::
% python3 -m tox -q -e py310 -- -n 0 -vv -k hash

You can also affect the test runs with environment variables:
- ``COVERAGE_ONE_CORE=1`` will use only one tracing core for each Python
version. This isn't about CPU cores, it's about the central code that tracks
execution. This will use the preferred core for the Python version and
implementation being tested.
- ``COVERAGE_TEST_CORES=...`` defines the cores to run tests on. Three cores
are available, specify them as a comma-separated string:
- ``ctrace`` is a sys.settrace function implemented in C.
- ``pytrace`` is a sys.settrace function implemented in Python.
- ``sysmon`` is a `sys.monitoring`_ implementation.
- ``COVERAGE_AST_DUMP=1`` will dump the AST tree as it is being used during
code parsing.
There are other environment variables that affect tests. I use `set_env.py`_
as a simple terminal interface to see and set them.
Of course, run all the tests on every version of Python you have before
submitting a change.
Lint, etc
---------
I try to keep the coverage.py source as clean as possible. I use pylint to
alert me to possible problems::
$ make lint
The source is pylint-clean, even if it's because there are pragmas quieting
some warnings. Please try to keep it that way, but don't let pylint warnings
keep you from sending patches. I can clean them up.
Lines should be kept to a 100-character maximum length. I recommend an
`editorconfig.org`_ plugin for your editor of choice, which will also help with
indentation, line endings and so on. Source files are formatted with `ruff`_.
I use `pre-commit`_ to run checks and formatting when making commits, you
should also.
Other style questions are best answered by looking at the existing code.
Formatting of docstrings, comments, long lines, and so on, should match the
code that already exists.
Cog
---
Parts of the documentation and GitHub actions are kept up-to-date with `cog`_.
There are checks to make sure that files are correct and not being incorrectly
edited.
If a check fails, it will show you what command to run to update the files.
If you edit parts of a file that should be generated, you will see a message
like::
Output has been edited! Delete old checksum to unprotect.
Probably you should revert the edits and run the command to generate the
output. The top of the file you edited will have instructions.
.. _cog: https://cog.readthedocs.io
Continuous integration
----------------------
When you make a pull request, `GitHub actions`__ will run all of the tests and
quality checks on your changes. If any fail, either fix them or ask for help.
__ https://github.com/nedbat/coveragepy/actions
Dependencies
------------
Coverage.py has no direct runtime dependencies, and I would like to keep it
that way.
It has many development dependencies. These are specified generically in the
``requirements/*.in`` files. The .in files should have no versions specified
in them. The specific versions to use are pinned in ``requirements/*.pip``
files. These are created by running ``make upgrade``.
.. minimum of PYVERSIONS:
It's important to use Python 3.10 to run ``make upgrade`` so that the pinned
versions will work on all of the Python versions currently supported by
coverage.py.
If for some reason we need to constrain a version of a dependency, the
constraint should be specified in the ``requirements/pins.pip`` file, with a
detailed reason for the pin.
Coverage testing coverage.py
----------------------------
Coverage.py can measure itself, but it's complicated. The process has been
packaged up to make it easier::
$ make metacov metahtml
Then look at htmlcov/index.html. Note that due to the recursive nature of
coverage.py measuring itself, there are some parts of the code that will never
appear as covered, even though they are executed.
Contributing
------------
When you are ready to contribute a change, any way you can get it to me is
probably fine. A pull request on GitHub is great, but a simple diff or
patch works too.
All contributions are expected to include tests for new functionality and
fixes. If you need help writing tests, please ask.

schema into the docs. If it's out of date, the quality checks will fail.
Running "make prebuild" will bring it up to date.
.. _dbschema:
===========================
Coverage.py database schema
===========================
.. versionadded:: 5.0
Coverage.py stores data in a SQLite database, by default called ``.coverage``.
For most needs, the :class:`.CoverageData` API will be sufficient, and should
be preferred to accessing the database directly. Only advanced uses will need
to use the database.
The schema can change without changing the major version of coverage.py, so be
careful when accessing the database directly. The ``coverage_schema`` table
has the schema number of the database. The schema described here corresponds
to:
.. [[[cog
from coverage.sqldata import SCHEMA_VERSION
print(".. code::")
print()
print(f" SCHEMA_VERSION = {SCHEMA_VERSION}")
print()
.. ]]]
.. code::
SCHEMA_VERSION = 7
.. [[[end]]] (sum: ladTQN8zI3)
You can use SQLite tools such as the :mod:`sqlite3 ` module in
the Python standard library to access the data. Some data is stored in a
packed format that will need custom functions to access. See
:func:`.register_sqlite_functions`.
Database schema
---------------
This is the database schema:
.. [[[cog
import textwrap
from coverage.sqldata import SCHEMA
print(".. code-block:: sql")
print()
print(textwrap.indent(SCHEMA, " "))
.. ]]]

-- 'when' text -- Datetime when the file was created.
);
CREATE TABLE file (

.. _excluding:
===============================
Excluding code from coverage.py
===============================
.. highlight:: python
You may have code in your project that you know won't be executed, and you want
to tell coverage.py to ignore it. For example, you may have debugging-only
code that won't be executed during your unit tests. You can tell coverage.py to
exclude this code during reporting so that it doesn't clutter your reports with
noise about code that you don't need to hear about.
Coverage.py will look for comments marking clauses for exclusion. In this
code, the "if debug" clause is excluded from reporting::
a = my_function1()
if debug: # pragma: no cover
msg = "blah blah"
log_message(msg, a)
b = my_function2()
By default, any line with a comment of ``pragma: no cover`` is excluded. If
that line introduces a clause, for example, an ``if`` clause, or a function or
class definition, then the entire clause is also excluded. Here the
``__repr__`` function is not reported as missing::
class MyObject(object):
def __init__(self):
blah1()
blah2()
def __repr__(self): # pragma: no cover
return ""
Excluded code is executed as usual, and its execution is recorded in the
coverage data as usual. When producing reports though, coverage.py excludes it
from the list of missing code.
Branch coverage
---------------
When measuring :ref:`branch coverage `, a conditional will not be
counted as a branch if one of its choices is excluded::
def only_one_choice(x):
if x:
blah1()
blah2()
else: # pragma: no cover
# x is always true.
blah3()
Because the ``else`` clause is excluded, the ``if`` only has one possible next
line, so it isn't considered a branch at all.
Default exclusions
------------------
Coverage.py has a set of built-in exclusion patterns. For line coverage, these
lines are automatically excluded:
- Any line with a comment like ``# pragma: no cover``. Other slight
differences in spacing and letter case are also recognized.
- Any line with only ``...`` in the code, for excluding placeholder function
bodies.
For branch coverage, these kinds of branches are automatically excluded:
- A branch with a comment like ``# pragma: no branch``, including differences
in spacing and letter case.
- Some branches that are known at compile time: ``if True:``, ``while True:``,
and so on.
- A branch just for type checkers: ``if TYPE_CHECKING:``.
.. versionadded:: 7.10.0 the ``...`` and ``TYPE_CHECKING`` defaults.
Advanced exclusion
------------------
Coverage.py identifies exclusions by matching source code against a list of
regular expressions. Using :ref:`configuration files ` or the coverage
:ref:`API `, you can add to that list. This is useful if you have
often-used constructs to exclude that can be matched with a regex. You can
exclude them all at once in your configuration without littering your code with
exclusion pragmas.
Before coverage.py 7.6.0, the regexes were matched against single lines of your
source code. Now they can be multi-line regexes that find matches across
lines. See :ref:`multi_line_exclude`.
If a matched line introduces a block, the entire block is excluded from
reporting. Matching a ``def`` line or decorator line will exclude an entire
function.
.. highlight:: ini
For example, you might decide that __repr__ functions are usually only used in
debugging code, and are uninteresting to test themselves. You could exclude
all of them by adding a regex to the exclusion list:
.. [[[cog
show_configs(
ini=r"""
[report]
exclude_also =
def __repr__
""",

The :ref:`config_report_exclude_also` option adds regexes to the built-in
default list so that you can add your own exclusions. The older
:ref:`config_report_exclude_lines` option completely overwrites the list of
regexes.
The regexes only have to match part of a line. Be careful not to over-match.
The regex ``...`` will match any line with more than three characters in it,
which is certainly not what you want to exclude.
.. _multi_line_exclude:
Multi-line exclusion regexes
----------------------------
.. versionadded:: 7.6.0
Exclusion regexes can match multi-line regions. All of the lines in a matched
region will be excluded. If part of the region introduces a block, the entire
block is excluded even if part of it is outside the matched region.
When writing regexes to match multiple lines, remember that ``"."`` won't match
a newline character, but ``"\n"`` or ``"(?s:.)"`` will. The regexes in these
settings are combined, so you cannot use global flags like ``(?s)`` in
your regexes. Use the scoped flag form instead: ``(?s:...)``
Here are some examples:
.. [[[cog

.. [[[end]]] (sum: xG6Bmtmh06)
The first regex matches a specific except line followed by a specific function
call. Both lines must be present for the exclusion to take effect. Note that
the regex uses ``"\n\s*"`` to match the newline and the indentation of the
second line. Without these, the regex won't match.
The second regex creates a pair of comments that can be used to exclude
statements between them. All lines between ``# no cover: start`` and ``# no
cover: stop`` will be excluded. The regex doesn't start with ``#`` because
that's a comment in a .coveragerc file. Be careful with wildcards: we've used
the non-greedy ``*?`` to match the fewest possible characters between the
comments. If you used the greedy ``*`` instead, the star would match as many
as possible, and you could accidentally exclude large swaths of code.
The third regex matches the entire text of a file containing the comment ``#
pragma: exclude file``. This lets you exclude files from coverage measurement
with an internal comment instead of naming them in a settings file. This regex
uses the ``"(?s:...)"`` regex flag to let a dot match any character including a
newline.

==================
FAQ and other help
==================
Frequently asked questions
--------------------------
Q: Why are some of my files not measured?
.........................................
Coverage.py has a number of mechanisms for deciding which files to measure and
which to skip. If your files aren't being measured, use the ``--debug=trace``
:ref:`option `, also settable as ``[run] debug=trace`` in the
:ref:`settings file `, or as ``COVERAGE_DEBUG=trace`` in an
environment variable.
This will write a line for each file considered, indicating whether it is
traced or not, and if not, why not. Be careful though: the output might be
swallowed by your test runner. If so, a ``COVERAGE_DEBUG_FILE=/tmp/cov.out``
environment variable can direct the output to a file instead to ensure you see
everything.
Q: Why do unexecutable lines show up as executed?
.................................................
Usually this is because you've updated your code and run coverage.py on it
again without erasing the old data. Coverage.py records line numbers executed,
so the old data may have recorded a line number which has since moved, causing
coverage.py to claim a line has been executed which cannot be.
If old data is persisting, you can use an explicit ``coverage erase`` command
to clean out the old data.
Q: Why are my function definitions marked as run when I haven't tested them?
............................................................................
The ``def`` and ``class`` lines in your Python file are executed when the file
is imported. Those are the lines that define your functions and classes. They
run even if you never call the functions. It's the body of the functions that
will be marked as not executed if you don't test them, not the ``def`` lines.
This can mean that your code has a moderate coverage total even if no tests
have been written or run. This might seem surprising, but it is accurate: the
``def`` lines have actually been run.
Q: Why do the bodies of functions show as executed, but the def lines do not?
.............................................................................
If this happens, it's because coverage.py has started after the functions are
defined. The definition lines are executed without coverage measurement, then
coverage.py is started, then the function is called. This means the body is
measured, but the definition of the function itself is not.
The same thing can happen with the bodies of classes.
To fix this, start coverage.py earlier. If you use the :ref:`command line
` to run your program with coverage.py, then your entire program will be
monitored. If you are using the :ref:`API `, you need to call
coverage.start() before importing the modules that define your functions.
Q: My decorator lines are marked as covered, but the "def" line is not. Why?
.............................................................................
Different versions of Python report execution on different lines. Coverage.py
adapts its behavior to the version of Python being used. In Python 3.7 and
earlier, a decorated function definition only reported the decorator as
executed. In Python 3.8 and later, both the decorator and the "def" are
reported. If you collect execution data on Python 3.7, and then run coverage
reports on Python 3.8, there will be a discrepancy.
Q: Can I find out which tests ran which lines?
..............................................
Yes! Coverage.py has a feature called :ref:`dynamic_contexts` which can collect
this information. Add this to your .coveragerc file:
.. code-block:: ini
[run]
dynamic_context = test_function
and then use the ``--contexts`` option when generating an HTML report.
Q: How is the total percentage calculated?
..........................................
For line coverage, coverage.py counts the total number of possible executions.
This is the number of executable statements minus the number of excluded
statements. It then counts the number of those possibilities that were
actually executed. The total percentage is the actual executions divided by
the possible executions.
As an example, a coverage report with 1514 statements and 901 missed
statements would calculate a total percentage of (1514-901)/1514, or 40.49%.
:ref:`Branch coverage ` extends the calculation to include the total
number of possible branch exits, and the number of those taken. In this case
the specific numbers shown in the text or HTML reports don't calculate out to
the percentage shown, because the number of missing branch exits isn't reported
explicitly. A branch line that wasn't executed at all is counted once as a
missing statement in the report, instead of as two missing branches. Reports
show the number of partial branches, which is the lines that were executed but
did not execute all of their exits.
The :ref:`JSON report ` includes more data that can be used to
re-calculate the total percentage. Individual files have a ``summary`` key,
and the report as a whole has a ``totals`` key that include items like these:
.. code-block:: json
{
"covered_branches": 5,
"covered_lines": 9,
"excluded_lines": 0,
"missing_branches": 11,
"missing_lines": 105,
"num_branches": 16,
"num_partial_branches": 5,
"num_statements": 114,
"percent_covered": 10.76923076923077,
"percent_covered_display": "11"
}
The total percentage is calculated as::
percent_covered =
(covered_lines + covered_branches) /
(num_statements + num_branches)
Q: Coverage.py is much slower than I remember, what's going on?
...............................................................
Make sure you are using the ``ctrace`` or ``sysmon`` core for measurement.
Coverage.py provides three different measurement cores. ``ctrace`` is the
default in Python versions up to 3.13, but might not be installed properly, in
which case the slower ``pytrace`` core is used.
``sysmon`` is the default in Python 3.14 and later, and is the fastest of the
three.
To see what you are running, add ``--debug=sys`` to your ``coverage run``
command line. The ``core=`` line will indicate which core is being used. The
output also includes a line that says either ``CTracer: available`` or
``CTracer: unavailable`` showing whether the ``ctrace`` core is installed and
usable. If it's not, try re-installing coverage.py to see what happened and if
you get the CTracer as you should.
If needed, you can request a specific core with the ``core=`` setting. See the
:ref:`core configuration ` documentation for details.
Q: Isn't coverage testing the best thing ever?
..............................................
It's good, but `it isn't perfect`__.

=====================
How coverage.py works
=====================
For advanced use of coverage.py, or just because you are curious, it helps to
understand what's happening behind the scenes.
Coverage.py works in three phases:
* **Execution**: Coverage.py runs your code, and monitors it to see what lines
were executed.
* **Analysis**: Coverage.py examines your code to determine what lines could
have run.
* **Reporting**: Coverage.py combines the results of execution and analysis to
produce coverage statistics and a report of missing execution.
The execution phase is handled by the ``coverage run`` command. The analysis
and reporting phases are handled by the reporting commands like ``coverage
report`` or ``coverage html``.
As a short-hand, I say that coverage.py measures what lines were executed, but
it collects more information than that. It can measure what branches were
taken, and if you have contexts enabled, for each line or branch, it will also
measure what contexts they were executed in.
Let's look at each phase in more detail.
Execution
---------
At the heart of the execution phase is a measurement core. It listens for
execution events from the Python interpreter, and captures raw data about what
has executed.
Coverage.py has three cores: ``ctrace`` and ``pytrace`` use trace functions
with `sys.settrace`_, and ``sysmon`` uses `sys.monitoring`_ for events.
- A **trace function** is a function that the Python interpreter invokes for
each line executed in a program. Coverage.py uses trace functions that
record each file and line number as it is executed. The ``ctrace`` trace
function is implemented in C for speed, while ``pytrace`` is implemented in
Python for portability.
For more details of trace functions, see the Python docs for `sys.settrace`_,
or if you are really brave, `How C trace functions really work`_.
Executing a function for every line in your program can make execution very
slow. Coverage.py's trace function is implemented in C to reduce that
overhead. It also takes care to not trace code that you aren't interested in.
- The **sys.monitoring** API is available on Python 3.12 and later. The
``sysmon`` core uses it to get execution events from the interpreter with
much lower overhead than trace functions.
It does this by disabling events once they have been seen. This means that
complex features like dynamic contexts are not supported yet, but for simple
line and branch coverage, it is much faster than trace functions.
When measuring branch coverage, the same event collectors are used, but instead
of recording line numbers, coverage.py records pairs of line numbers. Each
line event records the line number, then the next event records the pair
`(prev, this)` to indicate that execution transitioned from the previous line
to this line. Internally, these are called arcs.
As the data is being collected, coverage.py writes the data to a file, usually
named ``.coverage``. This is a :ref:`SQLite database ` containing
all of the measured data.
.. _sys.settrace: https://docs.python.org/3/library/sys.html#sys.settrace
.. _sys.monitoring: https://docs.python.org/3/library/sys.monitoring.html
.. _How C trace functions really work: https://nedbatchelder.com/text/trace-function.html
Plugins
.......
Of course coverage.py mostly measures execution of Python files. But it can
also be used to analyze other kinds of execution. :ref:`File tracer plugins
` provide support for non-Python files. For example,
Django HTML templates result in Python code being executed somewhere, but as a
developer, you want that execution mapped back to your .html template file.
During execution, each new Python file encountered is provided to the plugins
to consider. A plugin can claim the file and then convert the runtime Python
execution into source-level data to be recorded.
Dynamic contexts
................
When using :ref:`dynamic contexts `, there is a current
dynamic context that changes over the course of execution. It starts as empty.
While it is empty, every time a new function is entered, a check is made to see
if the dynamic context should change. While a non-empty dynamic context is
current, the check is skipped until the function that started the context
returns.
Analysis
--------
After your program has been executed and the line numbers recorded, coverage.py
needs to determine what lines could have been executed. Luckily, compiled
Python files (.pyc files) have a table of line numbers in them. Coverage.py
reads this table to get the set of executable lines, with a little more source
analysis to leave out things like docstrings.
The data file is read to get the set of lines that were executed. The
difference between the executable lines and the executed lines are the lines
that were not executed.
The same principle applies for branch measurement, though the process for
determining possible branches is more involved. Coverage.py uses the abstract
syntax tree of the Python source file to determine the set of possible
branches.
Reporting
---------
Once we have the set of executed lines and missing lines, reporting is a
matter of formatting that information in a useful way. Each reporting method
(text, HTML, JSON, annotated source, XML) has a different output format, but
the process is the same: write out the information in the particular format,
possibly including the source code itself.

===========
Coverage.py
===========
Coverage.py is a tool for measuring code coverage of Python programs. It
monitors your program, noting which parts of the code have been executed, then
analyzes the source to identify code that could have been executed but was not.
Coverage measurement is typically used to gauge the effectiveness of tests. It
can show which parts of your code are being exercised by tests, and which are
not.
The latest version is coverage.py |release|, released |release_date|. It is
supported on:
.. PYVERSIONS
* Python 3.10 through 3.15 alpha, including free-threading.
* PyPy3 versions 3.10 and 3.11.
.. ifconfig:: prerelease
**This is a pre-release build. The usual warnings about possible bugs
apply.** The latest stable version is coverage.py 6.5.0, `described here`_.

Quick start
-----------
Getting started is easy:
#. Install coverage.py::
$ python3 -m pip install coverage
For more details, see :ref:`install`.
#. Use ``coverage run`` to run your test suite and gather data. However you
normally run your test suite, you can use your test runner under coverage.
.. tip::
If your test runner command starts with "python", replace the initial
"python" with "coverage run".
``python something.py`` becomes ``coverage run something.py``
``python -m amodule`` becomes ``coverage run -m amodule``
Other instructions for specific test runners:
.. tabs::
.. tab:: pytest
If you usually use::
$ pytest arg1 arg2 arg3
then you can run your tests under coverage with::
$ coverage run -m pytest arg1 arg2 arg3
Many people choose to use the `pytest-cov`_ plugin, but for most
purposes, it is unnecessary.
.. tab:: unittest
Change your python command name to "coverage run", so this::
$ python3 -m unittest discover
becomes::
$ coverage run -m unittest discover
.. tab:: nosetest
.. note:: Nose has been `unmaintained since at least 2015 `_.
*You should seriously consider using a different test runner.*
Change this::
$ nosetests arg1 arg2
to::
$ coverage run -m nose arg1 arg2
Coverage doesn't distinguish between tests and the code being tested.
We `recommend that you include your tests in coverage measurement
