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](python/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
#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.
