v7.4.0
Compare Source
pytest 7.4.0 (2023-06-23)
Features
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
) ofskip
andxfail
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 aslog-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 apytest_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.

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 ofpy.error
andpy.path
modules but will use thepy
library if it is installed. If you need otherpy.*
modules, continue to install the deprecatedpy
library separately, otherwise it can usually be removed as a dependency.#4562: Deprecate configuring hook specs/impls using attributes/marks.
Instead use :py
pytest.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:
setup
andteardown
functions and methods: this might catch users by surprise, assetup()
andteardown()
are not pytest idioms, but part of thenose
support.For more details, consult the
deprecation docs <nose-deprecation>
{.interpreted-text role="ref"}.Features

.Improvements
#10218:
@pytest.mark.parametrize()
(and similar functions) now accepts anySequence[str]
for the argument names,instead of just
list[str]
andtuple[str, ...]
.(Note that
str
, which is itself aSequence[str]
, is still treated as acomma-delimited name list, as before).
#10381: The
--no-showlocals
flag has been added. This can be passed directly to tests to override--showlocals
declared throughaddopts
.#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 :py

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

now [bytes]{.title-ref}, [complex]{.title-ref}, [re.Pattern]{.title-ref}, [Enum]{.title-ref} and anything with a [__name__]{.title-ref} are also accepted.
#9692:
pytest.approx
{.interpreted-text role="func"} now raises aTypeError
{.interpreted-text role="class"} when given an unordered sequence (such asset
{.interpreted-text role="class"}).Note that this implies that custom classes which only implement
__iter__
and__len__
are no longer supported as they don't guarantee order.Bug Fixes
#8242: The deprecation of raising
unittest.SkipTest
{.interpreted-text role="class"} to skip collection oftests during the pytest collection phase is reverted - this is now a supported
feature again.
#9493: Symbolic link components are no longer resolved in conftest paths.
This means that if a conftest appears twice in collection tree, using symlinks, it will be executed twice.
For example, given
running
pytest tests
now imports the conftest twice, once astests/real/conftest.py
and once astests/link/conftest.py
.This is a fix to match a similar change made to test collection itself in pytest 6.0 (see
6523
{.interpreted-text role="pull"} for details).#9626: Fixed count of selected tests on terminal collection summary when there were errors or skipped modules.
If there were errors or skipped modules on collection, pytest would mistakenly subtract those from the selected count.
#9645: Fixed regression where
--import-mode=importlib
used together withPYTHONPATH
{.interpreted-text role="envvar"} orpythonpath
{.interpreted-text role="confval"} would cause import errors in test suites.#9708:
