v8.1.2
pytest 8.1.2 (2024-04-26)
Bug Fixes
-
#12114: Fixed error in
pytest.approx
{.interpreted-text role="func"} when used with [numpy]{.title-ref} arrays and comparing with other types.
v8.1.1
pytest 8.1.1 (2024-03-08)
::: {.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-ini
for 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-mode
option 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=importlib
would 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_module
xunit-style fixtures are not executed when--doctest-modules
is passed. -
#12014: Fix the
stacklevel
used when warning about marks used on fixtures. -
#12039: Fixed a regression in
8.0.2
where 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_path
fixture 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 aNode
itself instead of the nodeid. -
FixtureManager.getfixturedefs()
now takes theNode
itself 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
8.1.0
was 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
8.1.0
being yanked. -
pytest 8.1.0 (YANKED)
::: {.note} ::: {.title} Note :::
This release has been yanked: it broke some plugins without the proper warning period, due to some warnings not showing up as expected.
See #12069. :::

c:\MROGRA~1\tests
). -
#11953: Fix an
IndexError
crash raising fromgetstatementrange_ast
. - #12021: Reverted a fix to [--maxfail]{.title-ref} handling in pytest 8.0.0 because it caused a regression in pytest-xdist whereby session fixture teardowns may get executed multiple times when the max-fails is reached.
v8.0.1
pytest 8.0.1 (2024-02-16)
Bug Fixes
-
#11875: Correctly handle errors from
getpass.getuser

#11907: Fix a regression in pytest 8.0.0 whereby calling
pytest.skip
{.interpreted-text role="func"} and similar control-flow exceptions within apytest.warns()
{.interpreted-text role="func"} block would get suppressed instead of propagating. - #11929: Fix a regression in pytest 8.0.0 whereby autouse fixtures defined in a module get ignored by the doctests in the module.
- #11937: Fix a regression in pytest 8.0.0 whereby items would be collected in reverse order in some circumstances.
v8.0.0
See 8.0.0rc1 and 8.0.0rc2 for the full changes since pytest 7.4!
Bug Fixes

#11842: Properly escape the
reason
of askip <pytest.mark.skip ref>
{.interpreted-text role="ref"} mark when writing JUnit XML files. -
#11861: Avoid microsecond exceeds
1_000_000
when usinglog-date-format
