pytest 7.2.0 (2022-10-23)
Deprecations
* Update pytest.PytestUnhandledCoroutineWarning to a deprecation; it will raise an error in pytest 8.
* 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.
* Deprecate configuring hook specs/impls using attributes/marks.
Instead use pytest.hookimpl() and pytest.hookspec(). For more details, see the docs.
* 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.
* A deprecation warning is now emitted if a test function returns something other than None. This prevents a common mistake among beginners that expect that returning a bool (for example return foo(a, b) == result) would cause a test to pass or fail, instead of using assert. The plan is to make returning non-None from tests an error in the future.
Features
* Added shell-style wildcard support to testpaths.
Improvements
* @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).
* The --no-showlocals flag has been added. This can be passed directly to tests to override --showlocals declared through addopts.
* 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 expressed instead.
* Introduce multiline display for warning matching via pytest.warns() and enhance match comparison for _pytest._code.ExceptionInfo.match() as returned by pytest.raises().
* Improve pytest.raises(). Previously passing an empty tuple would give a confusing error. We now raise immediately with a more helpful message.
* On Python 3.11, use the standard library’s tomllib to parse TOML.
tomli is no longer a dependency on Python 3.11.
* Display assertion message without escaped newline characters with -vv.
* Improved error message that is shown when no collector is found for a given file.
* Some coloring has been added to the short test summary.
* Normalize the help description of all command-line options.
* Display full crash messages in short test summary info, when running in a CI environment.
* Added support for hidden configuration file by allowing .pytest.ini as an alternative to pytest.ini.
Bug Fixes
* sys.stdin now contains all expected methods of a file-like object when capture is enabled.
* Do not break into pdb when raise unittest.SkipTest() appears top-level in a file.
* 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 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() instead.
* 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.
* Ensure caplog.get_records(when) returns current/correct data after invoking caplog.clear().
Improved Documentation
* Update information on writing plugins to use pyproject.toml instead of setup.py.
* The documentation is now built using Sphinx 5.x (up from 3.x previously).
* Update documentation on how pytest.warns() affects DeprecationWarning.
Trivial/Internal Changes
* Made _pytest.doctest.DoctestItem export pytest.DoctestItem for type check and runtime purposes. Made _pytest.doctest use internal APIs to avoid circular imports.
* Made _pytest.compat re-export importlib_metadata in the eyes of type checkers.
* Fix default encoding warning (EncodingWarning) in cacheprovider
* 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.
