pytest-dev/pytest (pytest)

`v9.0.0`

Compare Source

pytest 9.0.0 (2025-11-05)

New features

#1367: Support for subtests has been added.

subtests <subtests> are an alternative to parametrization, useful in situations where the parametrization values are not all known at collection time.

Example:
```
def contains_docstring(p: Path) -> bool:
    """Return True if the given Python file contains a top-level docstring."""
    ...

def test_py_files_contain_docstring(subtests: pytest.Subtests) -> None:
    for path in Path.cwd().glob("*.py"):
        with subtests.test(path=str(path)):
            assert contains_docstring(path)
```
Each assert failure or error is caught by the context manager and reported individually, giving a clear picture of all files that are missing a docstring.

In addition, unittest.TestCase.subTest is now also supported.

This feature was originally implemented as a separate plugin in pytest-subtests, but since then has been merged into the core.

[!NOTE]
This feature is experimental and will likely evolve in future releases. By that we mean that we might change how subtests are reported on failure, but the functionality and how to use it are stable.
#13743: Added support for native TOML configuration files.

While pytest, since version 6, supports configuration in pyproject.toml files under [tool.pytest.ini_options],
it does so in an "INI compatibility mode", where all configuration values are treated as strings or list of strings.
Now, pytest supports the native TOML data model.

In pyproject.toml, the native TOML configuration is under the [tool.pytest] table.
```
# pyproject.toml
[tool.pytest]
minversion = "9.0"
addopts = ["-ra", "-q"]
testpaths = [
    "tests",
    "integration",
]
```
The [tool.pytest.ini_options] table remains supported, but both tables cannot be used at the same time.

If you prefer to use a separate configuration file, or don't use pyproject.toml, you can use pytest.toml or .pytest.toml:
```
# pytest.toml or .pytest.toml
[pytest]
minversion = "9.0"
addopts = ["-ra", "-q"]
testpaths = [
    "tests",
    "integration",
]
```
The documentation now (sometimes) shows configuration snippets in both TOML and INI formats, in a tabbed interface.

See config file formats for full details.
#13823: Added a "strict mode" enabled by the strict configuration option.

When set to true, the strict option currently enables
- strict_config
- strict_markers
- strict_parametrization_ids
- strict_xfail
The individual strictness options can be explicitly set to override the global strict setting.

The previously-deprecated --strict command-line flag now enables strict mode.

If pytest adds new strictness options in the future, they will also be enabled in strict mode.
Therefore, you should only enable strict mode if you use a pinned/locked version of pytest,
or if you want to proactively adopt new strictness options as they are added.

See strict mode for more details.
#13737: Added the strict_parametrization_ids configuration option.

When set, pytest emits an error if it detects non-unique parameter set IDs,
rather than automatically making the IDs unique by adding 0, 1, ... to them.
This can be particularly useful for catching unintended duplicates.
#13072: Added support for displaying test session progress in the terminal tab using the OSC 9;4; ANSI sequence.
When pytest runs in a supported terminal emulator like ConEmu, Gnome Terminal, Ptyxis, Windows Terminal, Kitty or Ghostty,
you'll see the progress in the terminal tab or window,
allowing you to monitor pytest's progress at a glance.

This feature is automatically enabled when running in a TTY. It is implemented as an internal plugin. If needed, it can be disabled as follows:
- On a user level, using -p no:terminalprogress on the command line or via an environment variable PYTEST_ADDOPTS='-p no:terminalprogress'.
- On a project configuration level, using addopts = "-p no:terminalprogress".
#478: Support PEP420 (implicit namespace packages) as --pyargs target when consider_namespace_packages is true in the config.

Previously, this option only impacted package imports, now it also impacts tests discovery.
#13678: Added a new faulthandler_exit_on_timeout configuration option set to "false" by default to let faulthandler interrupt the pytest process after a timeout in case of deadlock.

Previously, a faulthandler timeout would only dump the traceback of all threads to stderr, but would not interrupt the pytest process.

-- by ogrisel.
#13829: Added support for configuration option aliases via the aliases parameter in Parser.addini() <pytest.Parser.addini>.

Plugins can now register alternative names for configuration options,
allowing for more flexibility in configuration naming and supporting backward compatibility when renaming options.
The canonical name always takes precedence if both the canonical name and an alias are specified in the configuration file.

Improvements in existing functionality

#13330: Having pytest configuration spread over more than one file (for example having both a pytest.ini file and pyproject.toml with a [tool.pytest.ini_options] table) will now print a warning to make it clearer to the user that only one of them is actually used.

-- by sgaist
#13574: The single argument --version no longer loads the entire plugin infrastructure, making it faster and more reliable when displaying only the pytest version.

Passing --version twice (e.g., pytest --version --version) retains the original behavior, showing both the pytest version and plugin information.

[!NOTE]
Since --version is now processed early, it only takes effect when passed directly via the command line. It will not work if set through other mechanisms, such as PYTEST_ADDOPTS or addopts.
#13823: Added strict_xfail as an alias to the xfail_strict option,
strict_config as an alias to the --strict-config flag,
and strict_markers as an alias to the --strict-markers flag.
This makes all strictness options consistently have configuration options with the prefix strict_.
#13700: --junitxml no longer prints the generated xml file summary at the end of the pytest session when --quiet is given.
#13732: Previously, when filtering warnings, pytest would fail if the filter referenced a class that could not be imported. Now, this only outputs a message indicating the problem.
#13859: Clarify the error message for pytest.raises() when a regex match fails.
#13861: Better sentence structure in a test's expected error message. Previously, the error message would be "expected exception must be <expected>, but got <actual>". Now, it is "Expected <expected>, but got <actual>".

Removals and backward incompatible breaking changes

#12083: Fixed a bug where an invocation such as pytest a/ a/b would cause only tests from a/b to run, and not other tests under a/.

The fix entails a few breaking changes to how such overlapping arguments and duplicates are handled:
1. pytest a/b a/ or pytest a/ a/b are equivalent to pytest a; if an argument overlaps another arguments, only the prefix remains.
2. pytest x.py x.py is equivalent to pytest x.py; previously such an invocation was taken as an explicit request to run the tests from the file twice.
If you rely on these behaviors, consider using --keep-duplicates <duplicate-paths>, which retains its existing behavior (including the bug).
#13719: Support for Python 3.9 is dropped following its end of life.
#13766: Previously, pytest would assume it was running in a CI/CD environment if either of the environment variables $CI or $BUILD_NUMBER was defined;
now, CI mode is only activated if at least one of those variables is defined and set to a non-empty value.
#13779: PytestRemovedIn9Warning deprecation warnings are now errors by default.

Following our plan to remove deprecated features with as little disruption as
possible, all warnings of type PytestRemovedIn9Warning now generate errors
instead of warning messages by default.

The affected features will be effectively removed in pytest 9.1, so please consult the
deprecations section in the docs for directions on how to update existing code.

In the pytest 9.0.X series, it is possible to change the errors back into warnings as a
stopgap measure by adding this to your pytest.ini file:
```
[pytest]
filterwarnings =
    ignore::pytest.PytestRemovedIn9Warning
```
But this will stop working when pytest 9.1 is released.

If you have concerns about the removal of a specific feature, please add a
comment to 13779.

Deprecations (removal in next major release)

#13807: monkeypatch.syspath_prepend() <pytest.MonkeyPatch.syspath_prepend> now issues a deprecation warning when the prepended path contains legacy namespace packages (those using pkg_resources.declare_namespace()).
Users should migrate to native namespace packages (420).
See monkeypatch-fixup-namespace-packages for details.

Bug fixes

#13445: Made the type annotations of pytest.skip and friends more spec-complaint to have them work across more type checkers.
#13537: Fixed a bug in which ExceptionGroup with only Skipped exceptions in teardown was not handled correctly and showed as error.
#13598: Fixed possible collection confusion on Windows when short paths and symlinks are involved.
#13716: Fixed a bug where a nonsensical invocation like pytest x.py[a] (a file cannot be parametrized) was silently treated as pytest x.py. This is now a usage error.
#13722: Fixed a misleading assertion failure message when using pytest.approx on mappings with differing lengths.
#13773: Fixed the static fixture closure calculation to properly consider transitive dependencies requested by overridden fixtures.
#13816: Fixed pytest.approx which now returns a clearer error message when comparing mappings with different keys.
#13849: Hidden .pytest.ini files are now picked up as the config file even if empty.
This was an inconsistency with non-hidden pytest.ini.
#13865: Fixed --show-capture with --tb=line.
#13522: Fixed pytester in subprocess mode ignored all :attr`pytester.plugins <pytest.Pytester.plugins>` except the first.

Fixed pytester in subprocess mode silently ignored non-str pytester.plugins <pytest.Pytester.plugins>.
Now it errors instead.
If you are affected by this, specify the plugin by name, or switch the affected tests to use pytester.runpytest_inprocess <pytest.Pytester.runpytest_inprocess> explicitly instead.

Packaging updates and notes for downstreams

#13791: Minimum requirements on iniconfig and packaging were bumped to 1.0.1 and 22.0.0, respectively.

Contributor-facing changes

#12244: Fixed self-test failures when TERM=dumb.
#12474: Added scheduled GitHub Action Workflow to run Sphinx linkchecks in repo documentation.
#13621: pytest's own testsuite now handles the lsof command hanging (e.g. due to unreachable network filesystems), with the affected selftests being skipped after 10 seconds.
#13638: Fixed deprecated gh pr new command in scripts/prepare-release-pr.py.
The script now uses gh pr create which is compatible with GitHub CLI v2.0+.
#13695: Flush stdout and stderr in Pytester.run to avoid truncated outputs in test_faulthandler.py::test_timeout on CI -- by ogrisel.
#13771: Skip test_do_not_collect_symlink_siblings on Windows environments without symlink support to avoid false negatives.
#13841: tox>=4 is now required when contributing to pytest.
#13625: Added missing docstrings to pytest_addoption(), pytest_configure(), and cacheshow() functions in cacheprovider.py.

Miscellaneous internal changes

#13830: Configuration overrides (-o/--override-ini) are now processed during startup rather than during config.getini() <pytest.Config.getini>.

#11372: Async tests will now fail, instead of warning+skipping, if you don't have any suitable plugin installed.
#12346: Tests will now fail, instead of raising a warning, if they return any value other than None.
#12874: We dropped support for Python 3.8 following its end of life (2024-10-07).
#12960: Test functions containing a yield now cause an explicit error. They have not been run since pytest 4.0, and were previously marked as an expected failure and deprecation warning.

See the docs <yield tests deprecated>{.interpreted-text role="ref"} for more information.

Deprecations (removal in next major release)

#10839: Requesting an asynchronous fixture without a [pytest_fixture_setup]{.title-ref} hook that resolves it will now give a DeprecationWarning. This most commonly happens if a sync test requests an async fixture. This should have no effect on a majority of users with async tests or fixtures using async pytest plugins, but may affect non-standard hook setups or autouse=True. For guidance on how to work around this warning see sync-test-async-fixture{.interpreted-text role="ref"}.

New features

#11538: Added pytest.RaisesGroup{.interpreted-text role="class"} as an equivalent to pytest.raises{.interpreted-text role="func"} for expecting ExceptionGroup{.interpreted-text role="exc"}. Also adds pytest.RaisesExc{.interpreted-text role="class"} which is now the logic behind pytest.raises{.interpreted-text role="func"} and used as parameter to pytest.RaisesGroup{.interpreted-text role="class"}. RaisesGroup includes the ability to specify multiple different expected exceptions, the structure of nested exception groups, and flags for emulating except* <except_star>{.interpreted-text role="ref"}. See assert-matching-exception-groups{.interpreted-text role="ref"} and docstrings for more information.
#12081: Added capteesys{.interpreted-text role="fixture"} to capture AND pass output to next handler set by --capture=.
#12504: pytest.mark.xfail{.interpreted-text role="func"} now accepts pytest.RaisesGroup{.interpreted-text role="class"} for the raises parameter when you expect an exception group. You can also pass a pytest.RaisesExc{.interpreted-text role="class"} if you e.g. want to make use of the check parameter.
#12713: New [--force-short-summary]{.title-ref} option to force condensed summary output regardless of verbosity level.

This lets users still see condensed summary output of failures for quick reference in log files from job outputs, being especially useful if non-condensed output is very verbose.
#12749: pytest traditionally collects classes/functions in the test module namespace even if they are imported from another file.

For example:

contents of src/domain.py

class Testament: ...

contents of tests/test_testament.py

from domain import Testament

def test_testament(): ...
```

In this scenario with the default options, pytest will collect the class [Testament]{.title-ref} from [tests/test_testament.py]{.title-ref} because it starts with [Test]{.title-ref}, even though in this case it is a production class being imported in the test module namespace.

This behavior can now be prevented by setting the new `collect_imported_tests`{.interpreted-text role="confval"} configuration option to `false`, which will make pytest collect classes/functions from test files **only** if they are defined in that file.

#12765: Thresholds to trigger snippet truncation can now be set with truncation_limit_lines{.interpreted-text role="confval"} and truncation_limit_chars{.interpreted-text role="confval"}.

See truncation-params{.interpreted-text role="ref"} for more information.
#13125: console_output_style{.interpreted-text role="confval"} now supports times to show execution time of each test.
#13192: pytest.raises{.interpreted-text role="func"} will now raise a warning when passing an empty string to match, as this will match against any value. Use match="^$" if you want to check that an exception has no message.
#13192: pytest.raises{.interpreted-text role="func"} will now print a helpful string diff if matching fails and the match parameter has ^ and $ and is otherwise escaped.
#13192: You can now pass with pytest.raises(check=fn): <pytest.raises>{.interpreted-text role="func"}, where fn is a function which takes a raised exception and returns a boolean. The raises fails if no exception was raised (as usual), passes if an exception is raised and fn returns True (as well as match and the type matching, if specified, which are checked before), and propagates the exception if fn returns False (which likely also fails the test).
#13228: hidden-param{.interpreted-text role="ref"} can now be used in id of pytest.param{.interpreted-text role="func"} or in
ids of Metafunc.parametrize <pytest.Metafunc.parametrize>{.interpreted-text role="py:func"}.
It hides the parameter set from the test name.
#13253: New flag: --disable-plugin-autoload <disable_plugin_autoload>{.interpreted-text role="ref"} which works as an alternative to PYTEST_DISABLE_PLUGIN_AUTOLOAD{.interpreted-text role="envvar"} when setting environment variables is inconvenient; and allows setting it in config files with addopts{.interpreted-text role="confval"}.

Improvements in existing functionality

#10224: pytest's short and long traceback styles (how-to-modifying-python-tb-printing{.interpreted-text role="ref"})

#11118: Now pythonpath{.interpreted-text role="confval"} configures [$PYTHONPATH]{.title-ref} earlier than before during the initialization process, which now also affects plugins loaded via the [-p]{.title-ref} command-line option.

-- by millerdev{.interpreted-text role="user"}

#11381: The type parameter of the parser.addini method now accepts ["int"]{.title-ref} and "float" parameters, facilitating the parsing of configuration values in the configuration file.

Example:

def pytest_addoption(parser):
    parser.addini("int_value", type="int", default=2, help="my int value")
    parser.addini("float_value", type="float", default=4.2, help="my float value")

The [pytest.ini]{.title-ref} file:

[pytest]
int_value = 3
float_value = 5.4

#11525: Fixtures are now clearly represented in the output as a "fixture object", not as a normal function as before, making it easy for beginners to catch mistakes such as referencing a fixture declared in the same module but not requested in the test function.

-- by the-compiler{.interpreted-text role="user"} and glyphack{.interpreted-text role="user"}
#12426: A warning is now issued when pytest.mark.usefixtures ref{.interpreted-text role="ref"} is used without specifying any fixtures. Previously, empty usefixtures markers were silently ignored.
#12707: Exception chains can be navigated when dropped into Pdb in Python 3.13+.
#12736: Added a new attribute [name]{.title-ref} with the fixed value ["pytest tests"]{.title-ref} to the root tag [testsuites]{.title-ref} of the junit-xml generated by pytest.

This attribute is part of many junit-xml specifications and is even part of the [junit-10.xsd]{.title-ref} specification that pytest's implementation is based on.
#12943: If a test fails with an exceptiongroup with a single exception, the contained exception will now be displayed in the short test summary info.
#12958: A number of unraisable <unraisable>{.interpreted-text role="ref"} enhancements:
- Set the unraisable hook as early as possible and unset it as late as possible, to collect the most possible number of unraisable exceptions.
- Call the garbage collector just before unsetting the unraisable hook, to collect any straggling exceptions.
- Collect multiple unraisable exceptions per test phase.
- Report the tracemalloc{.interpreted-text role="mod"} allocation traceback (if available).
- Avoid using a generator based hook to allow handling StopIteration{.interpreted-text role="class"} in test failures.
- Report the unraisable exception as the cause of the pytest.PytestUnraisableExceptionWarning{.interpreted-text role="class"} exception if raised.
- Compute the repr of the unraisable object in the unraisable hook so you get the latest information if available, and should help with resurrection of the object.
#13010: pytest.approx{.interpreted-text role="func"} now can compare collections that contain numbers and non-numbers mixed.
#13016: A number of threadexception <unraisable>{.interpreted-text role="ref"} enhancements:
- Set the excepthook as early as possible and unset it as late as possible, to collect the most possible number of unhandled exceptions from threads.
- Collect multiple thread exceptions per test phase.
- Report the tracemalloc{.interpreted-text role="mod"} allocation traceback (if available).
- Avoid using a generator based hook to allow handling StopIteration{.interpreted-text role="class"} in test failures.
- Report the thread exception as the cause of the pytest.PytestUnhandledThreadExceptionWarning{.interpreted-text role="class"} exception if raised.
- Extract the name of the thread object in the excepthook which should help with resurrection of the thread.
#13031: An empty parameter set as in pytest.mark.parametrize([], ids=idfunc) will no longer trigger a call to idfunc with internal objects.
#13115: Allows supplying ExceptionGroup[Exception] and BaseExceptionGroup[BaseException] to pytest.raises to keep full typing on ExceptionInfo <pytest.ExceptionInfo>{.interpreted-text role="class"}:
```
with pytest.raises(ExceptionGroup[Exception]) as exc_info:
    some_function()
```
Parametrizing with other exception types remains an error - we do not check the types of child exceptions and thus do not permit code that might look like we do.
#13122: The --stepwise mode received a number of improvements:
- It no longer forgets the last failed test in case pytest is executed later without the flag.
  
  This enables the following workflow:
  1. Execute pytest with --stepwise, pytest then stops at the first failing test;
  2. Iteratively update the code and run the test in isolation, without the --stepwise flag (for example in an IDE), until it is fixed.
  3. Execute pytest with --stepwise again and pytest will continue from the previously failed test, and if it passes, continue on to the next tests.
  Previously, at step 3, pytest would start from the beginning, forgetting the previously failed test.
  
  This change however might cause issues if the --stepwise mode is used far apart in time, as the state might get stale, so the internal state will be reset automatically in case the test suite changes (for now only the number of tests are considered for this, we might change/improve this on the future).
- New --stepwise-reset/--sw-reset flag, allowing the user to explicitly reset the stepwise state and restart the workflow from the beginning.
#13308: Added official support for Python 3.14.
#13380: Fix ExceptionGroup{.interpreted-text role="class"} traceback filtering to exclude pytest internals.
#13415: The author metadata of the BibTex example is now correctly formatted with last names following first names.
An example of BibLaTex has been added.
BibTex and BibLaTex examples now clearly indicate that what is cited is software.

Creating virtualenv passwordless-HjuAhTfx-py3.14 in /home/ubuntu/.cache/pypoetry/virtualenvs

The current project's supported Python range (>=3.9) is not compatible with some of the required packages Python requirement:
  - pytest requires Python >=3.10, so it will not be satisfied for Python >=3.9,<3.10

Because passwordless depends on pytest (9.0.0) which requires Python >=3.10, version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For pytest, a possible solution would be to set the `python` property to ">=3.10"
