Prepare release version 7.4.0

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 replace ExceptionInfo.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) of skip and xfail reasons 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 %f directive to print microseconds in log format options, such as log-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 a pytest_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.

• #8711: caplog.set_level() <pytest.LogCaptureFixture.set_level>{.interpreted-text role="func"} and caplog.at_level() <pytest.LogCaptureFixture.at_level>{.interpreted-text role="func"}
  will temporarily enable the requested level if level was disabled globally via
  logging.disable(LEVEL).

Bug Fixes

• #10831: Terminal Reporting: Fixed bug when running in --tb=line mode where pytest.fail(pytrace=False) tests report None.
• #11068: Fixed the --last-failed whole-file skipping functionality ("skipped N files") for non-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 the testpaths are only considered when they are in use.
• #1904: Fixed traceback entries hidden with __tracebackhide__ = True still 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 -c to now include --config-file to make it clear that this flag applies to the usage of a custom config file.

7.3.2

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 long on 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 root conftests.
• #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).

7.3.1

pytest 7.3.1 (2023-04-14)

Improvements

• #10875: Python 3.12 support: fixed RuntimeError: TestResult has no addDuration method when running unittest tests.
• #10890: Python 3.12 support: fixed shutil.rmtree(onerror=...) deprecation warning when using tmp_path{.interpreted-text role="fixture"}.

Bug Fixes

• #10896: Fixed performance regression related to tmp_path{.interpreted-text role="fixture"} and the new tmp_path_retention_policy{.interpreted-text role="confval"} option.
• #10903: Fix crash INTERNALERROR IndexError: list index out of range which 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.

7.3.0

pytest 7.3.0 (2023-04-08)

Features

• #10525: Test methods decorated with @classmethod can 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 supports progress-even-when-capture-no to 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-disable CLI option added to disable individual loggers.
• #8141: Added tmp_path_retention_count{.interpreted-text role="confval"} and tmp_path_retention_policy{.interpreted-text role="confval"} configuration options to control how directories created by the tmp_path{.interpreted-text role="fixture"} fixture are kept.

Improvements

• #10226: If multiple errors are raised in teardown, we now re-raise an ExceptionGroup of them instead of discarding all but the last.
• #10658: Allow -p arguments to include spaces (eg: -p no:logging instead of
  -pno:logging). Mostly useful in the addopts section of the configuration
  file.
• #10710: Added start and stop timestamps to TestReport objects.
• #10727: Split the report header for rootdir, config file and testpaths so 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 raising OSError{.interpreted-text role="class"} on emscripten platform due to missing os.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 a version entry in pyproject.toml to 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).

7.2.2

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 teardown would be called as part of nose teardown stage.
• #10626: Fixed crash if --fixtures and --help are passed at the same time.
• #10660: Fixed :pypytest.raises{.interpreted-text role="func"} to return a 'ContextManager' so that type-checkers could narrow
  pytest.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.

7.2.1

pytest 7.2.1 (2023-01-13)

Bug Fixes

• #10452: Fix 'importlib.abc.TraversableResources' deprecation warning in Python 3.12.
• #10457: If a test is skipped from inside a fixture, the test summary now shows the test location instead of the fixture location.
• #10506: Fix bug where sometimes pytest would use the file system root directory as rootdir <rootdir>{.interpreted-text role="ref"} on Windows.
• #10607: Fix a race condition when creating junitxml reports, which could occur when multiple instances of pytest execute in parallel.
• #10641: Fix a race condition when creating or updating the stepwise plugin's cache, which could occur when multiple xdist worker nodes try to simultaneously update the stepwise plugin's cache.

7.2.0

pytest 7.2.0 (2022-10-23)

Deprecations

• #10012: Update pytest.PytestUnhandledCoroutineWarning{.interpreted-text role="class"} to a deprecation; it will raise an error in pytest 8.

• #10396: pytest no longer depends on the py library. pytest provides a vendored copy of py.error and py.path modules but will use the py library if it is installed. If you need other py.* modules, continue to install the deprecated py library separately, otherwise it can usually be removed as a dependency.

• #4562: Deprecate configuring hook specs/impls using attributes/marks.

  Instead use :pypytest.hookimpl{.interpreted-text role="func"} and :pypytest.hookspec{.interpreted-text role="func"}.
  For more details, see the docs <legacy-path-hooks-deprecated>{.interpreted-text role="ref"}.

• #9886: The functionality for running tests written for nose has been officially deprecated.

  This includes:

  • Plain setup and teardown functions and methods: this might catch users by surprise, as setup() and teardown() are not pytest idioms, but part of the nose support.
  • Setup/teardown using the @with_setup decorator.

  For more details, consult the deprecation docs <nose-deprecation>{.interpreted-text role="ref"}.

Features

• #9897: Added shell-style wildcard support to testpaths.

Improvements

• #10218: @pytest.mark.parametrize() (and similar functions) now accepts any Sequence[str] for the argument names,
  instead of just list[str] and tuple[str, ...].

  (Note that str, which is itself a Sequence[str], is still treated as a
  comma-delimited name list, as before).

• #10381: The --no-showlocals flag has been added. This can be passed directly to tests to override --showlocals declared through addopts.

• #3426: Assertion failures with strings in NFC and NFD forms that normalize to the same string now have a dedicated error message detailing the issue, and their utf-8 representation is expresed instead.

• #7337: A warning is now emitted if a test function returns something other than [None]{.title-ref}. This prevents a common mistake among beginners that expect that returning a [bool]{.title-ref} (for example [return foo(a, b) == result]{.title-ref}) would cause a test to pass or fail, instead of using [assert]{.title-ref}.

• #8508: Introduce multiline display for warning matching via :pypytest.warns{.interpreted-text role="func"} and
  enhance match comparison for :py_pytest._code.ExceptionInfo.match{.interpreted-text role="func"} as returned by :pypytest.raises{.interpreted-text role="func"}.

• #8646: Improve :pypytest.raises{.interpreted-text role="func"}. Previously passing an empty tuple would give a confusing
  error. We now raise immediately with a more helpful message.

• #9741: On Python 3.11, use the standard library's tomllib{.interpreted-text role="mod"} to parse TOML.

  tomli{.interpreted-text role="mod"}` is no longer a dependency on Python 3.11.

• #9742: Display assertion message without escaped newline characters with -vv.

• #9823: Improved error message that is shown when no collector is found for a given file.

• #9873: Some coloring has been added to the short test summary.

• #9883: Normalize the help description of all command-line options.

• #9920: Display full crash messages in short test summary info, when runng in a CI environment.

• #9987: Added support for hidden configuration file by allowing .pytest.ini as an alternative to pytest.ini.

Bug Fixes

• #10150: sys.stdin{.interpreted-text role="data"} now contains all expected methods of a file-like object when capture is enabled.

• #10382: Do not break into pdb when raise unittest.SkipTest() appears top-level in a file.

• #7792: Marks are now inherited according to the full MRO in test classes. Previously, if a test class inherited from two or more classes, only marks from the first super-class would apply.

  When inheriting marks from super-classes, marks from the sub-classes are now ordered before marks from the super-classes, in MRO order. Previously it was the reverse.

  When inheriting marks from super-classes, the [pytestmark]{.title-ref} attribute of the sub-class now only contains the marks directly applied to it. Previously, it also contained marks from its super-classes. Please note that this attribute should not normally be accessed directly; use pytest.Node.iter_markers{.interpreted-text role="func"} instead.

• #9159: Showing inner exceptions by forcing native display in ExceptionGroups even when using display options other than --tb=native. A temporary step before full implementation of pytest-native display for inner exceptions in ExceptionGroups.

• #9877: Ensure caplog.get_records(when) returns current/correct data after invoking caplog.clear().

Improved Documentation

• #10344: Update information on writing plugins to use pyproject.toml instead of setup.py.
• #9248: The documentation is now built using Sphinx 5.x (up from 3.x previously).
• #9291: Update documentation on how pytest.warns{.interpreted-text role="func"} affects DeprecationWarning{.interpreted-text role="class"}.

Trivial/Internal Changes

• #10196: ~pytest.PytestReturnNotNoneWarning{.interpreted-text role="class"} is now a subclass of ~pytest.PytestRemovedIn8Warning{.interpreted-text role="class"}: the plan is to make returning non-None from tests an error in the future.
• #10313: Made _pytest.doctest.DoctestItem export pytest.DoctestItem for
  type check and runtime purposes. Made [_pytest.doctest]{.title-ref} use internal APIs
  to avoid circular imports.
• #9906: Made _pytest.compat re-export importlib_metadata in the eyes of type checkers.
• #9910: Fix default encoding warning (EncodingWarning) in cacheprovider
• #9984: Improve the error message when we attempt to access a fixture that has been
  torn down.
  Add an additional sentence to the docstring explaining when it's not a good
  idea to call getfixturevalue.

7.1.3

pytest 7.1.3 (2022-08-31)

Bug Fixes

• #10060: When running with --pdb, TestCase.tearDown is no longer called for tests when the class has been skipped via unittest.skip or pytest.mark.skip.
• #10190: Invalid XML characters in setup or teardown error messages are now properly escaped for JUnit XML reports.
• #10230: Ignore .py files created by pyproject.toml-based editable builds introduced in pip 21.3.
• #3396: Doctests now respect the --import-mode flag.
• #9514: Type-annotate FixtureRequest.param as Any as a stop gap measure until 8073{.interpreted-text role="issue"} is fixed.
• #9791: Fixed a path handling code in rewrite.py that seems to work fine, but was incorrect and fails in some systems.
• #9917: Fixed string representation for pytest.approx{.interpreted-text role="func"} when used to compare tuples.

Improved Documentation

• #9937: Explicit note that tmpdir{.interpreted-text role="fixture"} fixture is discouraged in favour of tmp_path{.interpreted-text role="fixture"}.

Trivial/Internal Changes

• #10114: Replace atomicwrites dependency on windows with [os.replace]{.title-ref}.

7.1.2

pytest 7.1.2 (2022-04-23)

Bug Fixes

• #9726: An unnecessary numpy import inside pytest.approx{.interpreted-text role="func"} was removed.
• #9820: Fix comparison of dataclasses with InitVar.
• #9869: Increase stacklevel for the NODE_CTOR_FSPATH_ARG deprecation to point to the
  user's code, not pytest.
• #9871: Fix a bizarre (and fortunately rare) bug where the [temp_path]{.title-ref} fixture could raise
  an internal error while attempting to get the current user's username.

7.1.1

pytest 7.1.1 (2022-03-17)

Bug Fixes

• #9767: Fixed a regression in pytest 7.1.0 where some conftest.py files outside of the source tree (e.g. in the [site-packages]{.title-ref} directory) were not picked up.
