The 8.3.0 release failed to include the change notes and docs for the release. This patch release remedies this. There are no other changes.

New features

#12231: Added [--xfail-tb]{.title-ref} flag, which turns on traceback output for XFAIL results.
- If the [--xfail-tb]{.title-ref} flag is not given, tracebacks for XFAIL results are NOT shown.
- The style of traceback for XFAIL is set with [--tb]{.title-ref}, and can be [auto|long|short|line|native|no]{.title-ref}.
- Note: Even if you have [--xfail-tb]{.title-ref} set, you won't see them if [--tb=no]{.title-ref}.
Some history:
With pytest 8.0, [-rx]{.title-ref} or [-ra]{.title-ref} would not only turn on summary reports for xfail, but also report the tracebacks for xfail results. This caused issues with some projects that utilize xfail, but don't want to see all of the xfail tracebacks.
This change detaches xfail tracebacks from [-rx]{.title-ref}, and now we turn on xfail tracebacks with [--xfail-tb]{.title-ref}. With this, the default [-rx]{.title-ref}/ [-ra]{.title-ref} behavior is identical to pre-8.0 with respect to xfail tracebacks. While this is a behavior change, it brings default behavior back to pre-8.0.0 behavior, which ultimately was considered the better course of action.

#12281: Added support for keyword matching in marker expressions.
Now tests can be selected by marker keyword arguments. Supported values are
int{.interpreted-text role="class"}, (unescaped)str{.interpreted-text role="class"},bool{.interpreted-text role="class"} &None{.interpreted-text role="data"}.See
marker examples <marker_keyword_expression_example>{.interpreted-text role="ref"} for more information.-- by
lovetheguitar{.interpreted-text role="user"} -
#12567: Added
--no-fold-skippedcommand line option.If this option is set, then skipped tests in short summary are no longer grouped by reason but all tests are printed individually with their nodeid in the same way as other statuses.

Improvements in existing functionality
-
#12469: The console output now uses the "third-party plugins" terminology, replacing the previously established but confusing and outdated reference to
setuptools <setuptools:index>{.interpreted-text role="std:doc"} -- bywebknjaz{.interpreted-text role="user"}. -
#12544, #12545: Python virtual environment detection was improved by checking for a
pyvenv.cfg{.interpreted-text role="file"} file, ensuring reliable detection on various platforms -- byzachsnickers{.interpreted-text role="user"}. -
#2871: Do not truncate arguments to functions in output when running with [-vvv]{.title-ref}.
-
#389: The readability of assertion introspection of bound methods has been enhanced -- by
farbodahm{.interpreted-text role="user"},webknjaz{.interpreted-text role="user"},obestwalter{.interpreted-text role="user"},flub{.interpreted-text role="user"} andglyphack{.interpreted-text role="user"}.Earlier, it was like:
=================================== FAILURES =================================== _____________________________________ test _____________________________________ def test(): > assert Help().fun() == 2 E assert 1 == 2 E + where 1 = <bound method Help.fun of <example.Help instance at 0x256a830>>() E + where <bound method Help.fun of <example.Help instance at 0x256a830>> = <example.Help instance at 0x256a830>.fun E + where <example.Help instance at 0x256a830> = Help() example.py:7: AssertionError =========================== 1 failed in 0.03 seconds ===========================And now it's like:
=================================== FAILURES =================================== _____________________________________ test _____________________________________ def test(): > assert Help().fun() == 2 E assert 1 == 2 E + where 1 = fun() E + where fun = <test_local.Help object at 0x1074be230>.fun E + where <test_local.Help object at 0x1074be230> = Help() test_local.py:13: AssertionError =========================== 1 failed in 0.03 seconds =========================== -
#7662: Added timezone information to the testsuite timestamp in the JUnit XML report.
Bug fixes
-
#11706: Fixed reporting of teardown errors in higher-scoped fixtures when using [--maxfail]{.title-ref} or [--stepwise]{.title-ref}.
Originally added in pytest 8.0.0, but reverted in 8.0.2 due to a regression in pytest-xdist. This regression was fixed in pytest-xdist 3.6.1.
-
#11797:
pytest.approx{.interpreted-text role="func"} now correctly handlesSequence <collections.abc.Sequence>{.interpreted-text role="class"}-like objects. -
#12204, #12264: Fixed a regression in pytest 8.0 where tracebacks get longer and longer when multiple tests fail due to a shared higher-scope fixture which raised -- by
bluetech{.interpreted-text role="user"}.Also fixed a similar regression in pytest 5.4 for collectors which raise during setup.
The fix necessitated internal changes which may affect some plugins:
FixtureDef.cached_result[2]is now a tuple(exc, tb)instead ofexc.SetupState.stackfailures are now a tuple(exc, tb)instead ofexc.
-
#12275: Fixed collection error upon encountering an
abstract <abc>{.interpreted-text role="mod"} class, including abstract [unittest.TestCase]{.title-ref} subclasses. -
#12328: Fixed a regression in pytest 8.0.0 where package-scoped parameterized items were not correctly reordered to minimize setups/teardowns in some cases.
-
#12424: Fixed crash with [assert testcase is not None]{.title-ref} assertion failure when re-running unittest tests using plugins like pytest-rerunfailures. Regressed in 8.2.2.
-
#12472: Fixed a crash when returning category
"error"or"failed"with a custom test status frompytest_report_teststatus{.interpreted-text role="hook"} hook --pbrezina{.interpreted-text role="user"}. -
#12505: Improved handling of invalid regex patterns in
pytest.raises(match=r'...') <pytest.raises>{.interpreted-text role="func"} by providing a clear error message. -
#12580: Fixed a crash when using the cache class on Windows and the cache directory was created concurrently.
-
#6962: Parametrization parameters are now compared using [==]{.title-ref} instead of [is]{.title-ref} ([is]{.title-ref} is still used as a fallback if the parameter does not support [==]{.title-ref}). This fixes use of parameters such as lists, which have a different [id]{.title-ref} but compare equal, causing fixtures to be re-computed instead of being cached.
-
#7166: Fixed progress percentages (the
[ 87%]at the edge of the screen) sometimes not aligning correctly when running with pytest-xdist-n.
Improved documentation
-
#12153: Documented using
PYTEST_VERSION{.interpreted-text role="envvar"} to detect if code is running from within a pytest run. -
#12469: The external plugin mentions in the documentation now avoid mentioning
setuptools entry-points <setuptools:index>{.interpreted-text role="std:doc"} as the concept is much more generic nowadays. Instead, the terminology of "external", "installed", or "third-party" plugins (or packages) replaces that.-- by
webknjaz{.interpreted-text role="user"} -
#12577: [CI]{.title-ref} and [BUILD_NUMBER]{.title-ref} environment variables role is discribed in the reference doc. They now also appear when doing [pytest -h]{.title-ref} -- by
MarcBresson{.interpreted-text role="user"}.
Contributor-facing changes
-
#12467: Migrated all internal type-annotations to the python3.10+ style by using the [annotations]{.title-ref} future import.
-- by
RonnyPfannschmidt{.interpreted-text role="user"} -
#11771, #12557: The PyPy runtime version has been updated to 3.9 from 3.8 that introduced a flaky bug at the garbage collector which was not expected to fix there as the 3.8 is EoL.
-- by
x612skm{.interpreted-text role="user"} -
#12493: The change log draft preview integration has been refactored to use a third party extension
sphinxcontib-towncrier. The previous in-repo script was putting the change log preview file atdoc/en/_changelog_towncrier_draft.rst{.interpreted-text role="file"}. Said file is no longer ignored in Git and might show up among untracked files in the development environments of the contributors. To address that, the contributors can run the following command that will clean it up:$ git clean -x -i -- doc/en/_changelog_towncrier_draft.rst-- by
webknjaz{.interpreted-text role="user"} -
#12498: All the undocumented
toxenvironments now have descriptions. They can be listed in one's development environment by invokingtox -avin a terminal.-- by
webknjaz{.interpreted-text role="user"} -
#12501: The changelog configuration has been updated to introduce more accurate audience-tailored categories. Previously, there was a
trivialchange log fragment type with an unclear and broad meaning. It was removed and we now havecontrib,miscandpackagingin place of it.The new change note types target the readers who are downstream packagers and project contributors. Additionally, the miscellaneous section is kept for unspecified updates that do not fit anywhere else.
-- by
webknjaz{.interpreted-text role="user"} -
#12502: The UX of the GitHub automation making pull requests to update the plugin list has been updated. Previously, the maintainers had to close the automatically created pull requests and re-open them to trigger the CI runs. From now on, they only need to click the [Ready for review]{.title-ref} button instead.
-- by
webknjaz{.interpreted-text role="user"} -
#12522: The
:pull:RST role has been replaced with a shorter:pr:due to starting to use the implementation from the third-partysphinx-issues{.interpreted-text role="pypi"} Sphinx extension -- bywebknjaz{.interpreted-text role="user"}. -
#12531: The coverage reporting configuration has been updated to exclude pytest's own tests marked as expected to fail from the coverage report. This has an effect of reducing the influence of flaky tests on the resulting number.
-- by
webknjaz{.interpreted-text role="user"} -
#12533: The
extlinksSphinx extension is no longer enabled. The:bpo:role it used to declare has been removed with that. BPO itself has migrated to GitHub some years ago and it is possible to link the respective issues by using their GitHub issue numbers and the:issue:role that thesphinx-issuesextension implements.-- by
webknjaz{.interpreted-text role="user"} -
#12562: Possible typos in using the
:user:RST role is now being linted through the pre-commit tool integration -- bywebknjaz{.interpreted-text role="user"}.

v8.2.0
pytest 8.2.0 (2024-04-27)
Deprecations
-
#12069: A deprecation warning is now raised when implementations of one of the following hooks request a deprecated
py.path.localparameter instead of thepathlib.Pathparameter which replaced it:pytest_ignore_collect{.interpreted-text role="hook"} - thepathparameter - usecollection_pathinstead.pytest_collect_file{.interpreted-text role="hook"} - thepathparameter - usefile_pathinstead.pytest_pycollect_makemodule{.interpreted-text role="hook"} - thepathparameter - usemodule_pathinstead.pytest_report_header{.interpreted-text role="hook"} - thestartdirparameter - usestart_pathinstead.pytest_report_collectionfinish{.interpreted-text role="hook"} - thestartdirparameter - usestart_pathinstead.
The replacement parameters are available since pytest 7.0.0. The old parameters will be removed in pytest 9.0.0.
See
legacy-path-hooks-deprecated{.interpreted-text role="ref"} for more details.
Features
-
#11871: Added support for reading command line arguments from a file using the prefix character
@, like e.g.:pytest @​tests.txt. The file must have one argument per line.See
Read arguments from file <args-from-file>{.interpreted-text role="ref"} for details.
Improvements
-
#11523:
pytest.importorskip{.interpreted-text role="func"} will now issue a warning if the module could be found, but raisedImportError{.interpreted-text role="class"} instead ofModuleNotFoundError{.interpreted-text role="class"}.The warning can be suppressed by passing
exc_type=ImportErrortopytest.importorskip{.interpreted-text role="func"}.See
import-or-skip-import-error{.interpreted-text role="ref"} for details. -
#11728: For
unittest-based tests, exceptions during class cleanup (as raised by functions registered withTestCase.addClassCleanup <unittest.TestCase.addClassCleanup>{.interpreted-text role="meth"}) are now reported instead of silently failing. -
#11777: Text is no longer truncated in the
short test summary infosection when-vvis given. -
#12112: Improved namespace packages detection when
consider_namespace_packages{.interpreted-text role="confval"} is enabled, covering more situations (like editable installs). -
#9502: Added
PYTEST_VERSION{.interpreted-text role="envvar"} environment variable which is defined at the start of the pytest session and undefined afterwards. It contains the value ofpytest.__version__, and among other things can be used to easily check if code is running from within a pytest run.
Bug Fixes
-
#12065: Fixed a regression in pytest 8.0.0 where test classes containing
setup_methodand tests using@staticmethodor@classmethodwould crash withAttributeError: 'NoneType' object has no attribute 'setup_method'.Now the
request.instance <pytest.FixtureRequest.instance>{.interpreted-text role="attr"} attribute of tests using@staticmethodand@classmethodis no longerNone, but a fresh instance of the class, like in non-static methods. Previously it wasNone, and all fixtures of such tests would share a singleself. -
#12135: Fixed issue where fixtures adding their finalizer multiple times to fixtures they request would cause unreliable and non-intuitive teardown ordering in some instances.
-
#12194: Fixed a bug with
--importmode=importliband--doctest-moduleswhere child modules did not appear as attributes in parent modules. -
#1489: Fixed some instances where teardown of higher-scoped fixtures was not happening in the reverse order they were initialized in.
Trivial/Internal Changes
- #12069:
pluggy>=1.5.0is now required. - #12167:
cache <cache>{.interpreted-text role="ref"}: create supporting files (CACHEDIR.TAG,.gitignore, etc.) in a temporary directory to provide atomic semantics.
v8.1.2
pytest 8.1.2 (2024-04-26)

::: {.note} ::: {.title} Note :::
This release is not a usual bug fix release -- it contains features and improvements, being a follow up
to 8.1.0, which has been yanked from PyPI.
:::
Features
-
#11475: Added the new
consider_namespace_packages{.interpreted-text role="confval"} configuration option, defaulting toFalse.If set to
True, pytest will attempt to identify modules that are part of namespace packages when importing modules. -
#11653: Added the new
verbosity_test_cases{.interpreted-text role="confval"} configuration option for fine-grained control of test execution verbosity. SeeFine-grained verbosity <pytest.fine_grained_verbosity>{.interpreted-text role="ref"} for more details.
Improvements
-
#10865:
pytest.warns{.interpreted-text role="func"} now validates thatwarnings.warn{.interpreted-text role="func"} was called with a [str]{.title-ref} or a [Warning]{.title-ref}. Currently in Python it is possible to use other types, however this causes an exception whenwarnings.filterwarnings{.interpreted-text role="func"} is used to filter those warnings (see CPython #103577 for a discussion). While this can be considered a bug in CPython, we decided to put guards in pytest as the error message produced without this check in place is confusing. -
#11311: When using
--override-inifor paths in invocations without a configuration file defined, the current working directory is used as the relative directory.Previoulsy this would raise an
AssertionError{.interpreted-text role="class"}. -
#11475:
--import-mode=importlib <import-mode-importlib>{.interpreted-text role="ref"} now tries to import modules using the standard import mechanism (but still without changing :pysys.path{.interpreted-text role="data"}), falling back to importing modules directly only if that fails.This means that installed packages will be imported under their canonical name if possible first, for example
app.core.models, instead of having the module name always be derived from their path (for example.env310.lib.site_packages.app.core.models). -
#11801: Added the
iter_parents() <_pytest.nodes.Node.iter_parents>{.interpreted-text role="func"} helper method on nodes. It is similar tolistchain <_pytest.nodes.Node.listchain>{.interpreted-text role="func"}, but goes from bottom to top, and returns an iterator, not a list. -
#11850: Added support for
sys.last_exc{.interpreted-text role="data"} for post-mortem debugging on Python>=3.12. -
#11962: In case no other suitable candidates for configuration file are found, a
pyproject.toml(even without a[tool.pytest.ini_options]table) will be considered as the configuration file and define therootdir. -
#11978: Add
--log-file-modeoption to the logging plugin, enabling appending to log-files. This option accepts either"w"or"a"and defaults to"w".Previously, the mode was hard-coded to be
"w"which truncates the file before logging. -
#12047: When multiple finalizers of a fixture raise an exception, now all exceptions are reported as an exception group. Previously, only the first exception was reported.
Bug Fixes
-
#11475: Fixed regression where
--importmode=importlibwould import non-test modules more than once. -
#11904: Fixed a regression in pytest 8.0.0 that would cause test collection to fail due to permission errors when using
--pyargs.This change improves the collection tree for tests specified using
--pyargs, see12043{.interpreted-text role="pull"} for a comparison with pytest 8.0 and <8. -
#12011: Fixed a regression in 8.0.1 whereby
setup_modulexunit-style fixtures are not executed when--doctest-modulesis passed. -
#12014: Fix the
stacklevelused when warning about marks used on fixtures. -
#12039: Fixed a regression in
8.0.2where tests created usingtmp_path{.interpreted-text role="fixture"} have been collected multiple times in CI under Windows.
Improved Documentation
- #11790: Documented the retention of temporary directories created using the
tmp_pathfixture in more detail.
Trivial/Internal Changes
-
#11785: Some changes were made to private functions which may affect plugins which access them:
FixtureManager._getautousenames()now takes aNodeitself instead of the nodeid.FixtureManager.getfixturedefs()now takes theNodeitself instead of the nodeid.- The
_pytest.nodes.iterparentnodeids()function is removed without replacement. Prefer to traverse the node hierarchy itself instead. If you really need to, copy the function from the previous pytest release.
-
#12069: Delayed the deprecation of the following features to
9.0.0:node-ctor-fspath-deprecation{.interpreted-text role="ref"}.legacy-path-hooks-deprecated{.interpreted-text role="ref"}.
It was discovered after
8.1.0was released that the warnings about the impeding removal were not being displayed, so the team decided to revert the removal.This is the reason for

v7.4.0
pytest 7.4.0 (2023-06-23)
Features
- #10901: Added
ExceptionInfo.from_exception() <pytest.ExceptionInfo.from_exception>{.interpreted-text role="func"}, a simpler way to create an~pytest.ExceptionInfo{.interpreted-text role="class"} from an exception. This can replaceExceptionInfo.from_exc_info() <pytest.ExceptionInfo.from_exc_info()>{.interpreted-text role="func"} for most uses.
Improvements
-
#10872: Update test log report annotation to named tuple and fixed inconsistency in docs for
pytest_report_teststatus{.interpreted-text role="hook"} hook. -
#10907: When an exception traceback to be displayed is completely filtered out (by mechanisms such as
__tracebackhide__, internal frames, and similar), now only the exception string and the following message are shown:"All traceback entries are hidden. Pass [--full-trace]{.title-ref} to see hidden and internal frames.".
Previously, the last frame of the traceback was shown, even though it was hidden.
-
#10940: Improved verbose output (
-vv) ofskipandxfailreasons by performing text wrapping while leaving a clear margin for progress output.Added
TerminalReporter.wrap_write()as a helper for that. -
#10991: Added handling of
%fdirective to print microseconds in log format options, such aslog-date-format. -
#11005: Added the underlying exception to the cache provider's path creation and write warning messages.
-
#11013: Added warning when
testpaths{.interpreted-text role="confval"} is set, but paths are not found by glob. In this case, pytest will fall back to searching from the current directory. -
#11043: When [--confcutdir]{.title-ref} is not specified, and there is no config file present, the conftest cutoff directory ([--confcutdir]{.title-ref}) is now set to the
rootdir <rootdir>{.interpreted-text role="ref"}. Previously in such cases, [conftest.py]{.title-ref} files would be probed all the way to the root directory of the filesystem. If you are badly affected by this change, consider adding an empty config file to your desired cutoff directory, or explicitly set [--confcutdir]{.title-ref}. -
#11081: The
norecursedirs{.interpreted-text role="confval"} check is now performed in apytest_ignore_collect{.interpreted-text role="hook"} implementation, so plugins can affect it.If after updating to this version you see that your [norecursedirs]{.title-ref} setting is not being respected, it means that a conftest or a plugin you use has a bad [pytest_ignore_collect]{.title-ref} implementation. Most likely, your hook returns [False]{.title-ref} for paths it does not want to ignore, which ends the processing and doesn't allow other plugins, including pytest itself, to ignore the path. The fix is to return [None]{.title-ref} instead of [False]{.title-ref} for paths your hook doesn't want to ignore.

Bug Fixes
- #10831: Terminal Reporting: Fixed bug when running in
--tb=linemode wherepytest.fail(pytrace=False)tests reportNone. - #11068: Fixed the
--last-failedwhole-file skipping functionality ("skipped N files") fornon-python test files <non-python tests>{.interpreted-text role="ref"}. - #11104: Fixed a regression in pytest 7.3.2 which caused to
testpaths{.interpreted-text role="confval"} to be considered for loading initial conftests, even when it was not utilized (e.g. when explicit paths were given on the command line). Now thetestpathsare only considered when they are in use. - #1904: Fixed traceback entries hidden with
__tracebackhide__ = Truestill being shown for chained exceptions (parts after "... the above exception ..." message). - #7781: Fix writing non-encodable text to log file when using
--debug.
Improved Documentation
- #9146: Improved documentation for
caplog.set_level() <pytest.LogCaptureFixture.set_level>{.interpreted-text role="func"}.
Trivial/Internal Changes
- #11031: Enhanced the CLI flag for
-cto now include--config-fileto make it clear that this flag applies to the usage of a custom config file.
v7.3.2
pytest 7.3.2 (2023-06-10)
Bug Fixes
- #10169: Fix bug where very long option names could cause pytest to break with
OSError: [Errno 36] File name too longon some systems. - #10894: Support for Python 3.12 (beta at the time of writing).
- #10987:
testpaths{.interpreted-text role="confval"} is now honored to load rootconftests. - #10999: The [monkeypatch]{.title-ref} [setitem]{.title-ref}/[delitem]{.title-ref} type annotations now allow [TypedDict]{.title-ref} arguments.
- #11028: Fixed bug in assertion rewriting where a variable assigned with the walrus operator could not be used later in a function call.
- #11054: Fixed
--last-failed's "(skipped N files)" functionality for files inside of packages (directories with [__init__.py]{.title-ref} files).
v7.3.1
pytest 7.3.1 (2023-04-14)
Improvements
- #10875: Python 3.12 support: fixed
RuntimeError: TestResult has no addDuration methodwhen runningunittesttests. - #10890: Python 3.12 support: fixed
shutil.rmtree(onerror=...)deprecation warning when usingtmp_path{.interpreted-text role="fixture"}.
Bug Fixes
- #10896: Fixed performance regression related to
tmp_path{.interpreted-text role="fixture"} and the newtmp_path_retention_policy{.interpreted-text role="confval"} option. - #10903: Fix crash
INTERNALERROR IndexError: list index out of rangewhich happens when displaying an exception where all entries are hidden. This reverts the change "Correctly handle__tracebackhide__for chained exceptions." introduced in version 7.3.0.
v7.3.0
pytest 7.3.0 (2023-04-08)
Features
- #10525: Test methods decorated with
@classmethodcan now be discovered as tests, following the same rules as normal methods. This fills the gap that static methods were discoverable as tests but not class methods. - #10755:
console_output_style{.interpreted-text role="confval"} now supportsprogress-even-when-capture-noto force the use of the progress output even when capture is disabled. This is useful in large test suites where capture may have significant performance impact. - #7431:
--log-disableCLI option added to disable individual loggers. - #8141: Added
tmp_path_retention_count{.interpreted-text role="confval"} andtmp_path_retention_policy{.interpreted-text role="confval"} configuration options to control how directories created by thetmp_path{.interpreted-text role="fixture"} fixture are kept.
Improvements
- #10226: If multiple errors are raised in teardown, we now re-raise an
ExceptionGroupof them instead of discarding all but the last. - #10658: Allow
-parguments to include spaces (eg:-p no:logginginstead of-pno:logging). Mostly useful in theaddoptssection of the configuration file. - #10710: Added
startandstoptimestamps toTestReportobjects. - #10727: Split the report header for
rootdir,config fileandtestpathsso each has its own line. - #10840: pytest should no longer crash on AST with pathological position attributes, for example testing AST produced by [Hylang <https://github.com/hylang/hy>__]{.title-ref}.
- #6267: The full output of a test is no longer truncated if the truncation message would be longer than the hidden text. The line number shown has also been fixed.
Bug Fixes
- #10743: The assertion rewriting mechanism now works correctly when assertion expressions contain the walrus operator.
- #10765: Fixed
tmp_path{.interpreted-text role="fixture"} fixture always raisingOSError{.interpreted-text role="class"} onemscriptenplatform due to missingos.getuid{.interpreted-text role="func"}. - #1904: Correctly handle
__tracebackhide__for chained exceptions.
Improved Documentation
- #10782: Fixed the minimal example in
goodpractices{.interpreted-text role="ref"}:pip install -e .requires aversionentry inpyproject.tomlto run successfully.
Trivial/Internal Changes
- #10669: pytest no longer depends on the [attrs]{.title-ref} package (don't worry, nice diffs for attrs classes are still supported).
v7.2.2
pytest 7.2.2 (2023-03-03)
Bug Fixes
- #10533: Fixed
pytest.approx{.interpreted-text role="func"} handling of dictionaries containing one or more values of [0.0]{.title-ref}. - #10592: Fixed crash if [--cache-show]{.title-ref} and [--help]{.title-ref} are passed at the same time.
- #10597: Fixed bug where a fixture method named
teardownwould be called as part ofnoseteardown stage. - #10626: Fixed crash if
--fixturesand--helpare passed at the same time. - #10660: Fixed :py
pytest.raises{.interpreted-text role="func"} to return a 'ContextManager' so that type-checkers could narrowpytest.raises(...) if ... else nullcontext()down to 'ContextManager' rather than 'object'.
Improved Documentation
- #10690: Added [CI]{.title-ref} and [BUILD_NUMBER]{.title-ref} environment variables to the documentation.
- #10721: Fixed entry-points declaration in the documentation example using Hatch.
- #10753: Changed wording of the module level skip to be very explicit about not collecting tests and not executing the rest of the module.
