v7.4.0Compare 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) ofskipandxfailreasons 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
%fdirective 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.

#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-showlocalsflag has been added. This can be passed directly to tests to override--showlocalsdeclared 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}.

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

This means that if a conftest appears twice in collection tree, using symlinks, it will be executed twice.

#7259: The
Node.reportinfo() <non-python tests>{.interpreted-text role="ref"} function first return value type has been expanded from [py.path.local | str]{.title-ref} to [os.PathLike[str] | str]{.title-ref}.Most plugins which refer to [reportinfo()]{.title-ref} only define it as part of a custom
pytest.Item{.interpreted-text role="class"} implementation.Since [py.path.local]{.title-ref} is a [os.PathLike[str]]{.title-ref}, these plugins are unaffacted.
Plugins and users which call [reportinfo()]{.title-ref}, use the first return value and interact with it as a [py.path.local]{.title-ref}, would need to adjust by calling [py.path.local(fspath)]{.title-ref}.
Although preferably, avoid the legacy [py.path.local]{.title-ref} and use [pathlib.Path]{.title-ref}, or use [item.location]{.title-ref} or [item.path]{.title-ref}, instead.
Note: pytest was not able to provide a deprecation period for this change.

Note
:::
The name of the
~_pytest.nodes.Node{.interpreted-text role="class"} arguments and attributes (thenew attribute being
path) is the opposite of the situation for hooks(the old argument being
path).This is an unfortunate artifact due to historical reasons, which should be
resolved in future versions as we slowly get rid of the
py{.interpreted-text role="pypi"}dependency (see
9283{.interpreted-text role="issue"} for a longer discussion).:::
#7469: Directly constructing the following classes is now deprecated:

#8242: Raising
unittest.SkipTest{.interpreted-text role="class"} to skip collection of tests during thepytest collection phase is deprecated. Use
pytest.skip{.interpreted-text role="func"} instead.Note: This deprecation only relates to using
unittest.SkipTest{.interpreted-text role="class"} during testcollection. You are probably not doing that. Ordinary usage of
unittest.SkipTest{.interpreted-text role="class"} /unittest.TestCase.skipTest{.interpreted-text role="meth"} /unittest.skip{.interpreted-text role="func"} in unittest test cases is fully supported.#8315: Several behaviors of

the deprecation note <cmdline-preparse-deprecated>{.interpreted-text role="ref"} for full details.#8645:
pytest.warns(None) <pytest.warns>{.interpreted-text role="func"} is now deprecated because many people usedit to mean "this code does not emit warnings", but it actually had the effect of
checking that the code emits at least one warning of any type - like

Features
#5196: Tests are now ordered by definition order in more cases.
In a class hierarchy, tests from base classes are now consistently ordered before tests defined on their subclasses (reverse MRO order).
#7132: Added two environment variables
PYTEST_THEME{.interpreted-text role="envvar"} andPYTEST_THEME_MODE{.interpreted-text role="envvar"} to let the users customize the pygments theme used.#7259: Added

pathstype toparser.addini() <pytest.Parser.addini>{.interpreted-text role="meth"},as in
parser.addini("mypaths", "my paths", type="paths"),which is similar to the existing

Doing so will emit a deprecation warning, and may become a hard-error in pytest 8.0.
Subclassing them is also not supported. This is not currently enforced at runtime, but is detected by type-checkers such as mypy.

--fixtures-per-testand--fixtureshave been enriched with:--verboseoption.#8761: New
version-tuple{.interpreted-text role="ref"} attribute, which makes it simpler for users to do something depending on the pytest version (such as declaring hooks which are introduced in later versions).#8789: Switch TOML parser from
tomltotomlifor TOML v1.0.0 support inpyproject.toml.#8920: Added
pytest.Stash{.interpreted-text role="class"}, a facility for plugins to store their data on~pytest.Config{.interpreted-text role="class"} and~_pytest.nodes.Node{.interpreted-text role="class"}s in a type-safe and conflict-free manner.See

If you currently use the pytest-pythonpath or pytest-srcpaths plugins, you should be able to replace them with built-in [pythonpath]{.title-ref} setting.Improvements
#7480: A deprecation scheduled to be removed in a major version X (e.g. pytest 7, 8, 9, ...) now uses warning category [PytestRemovedInXWarning]{.title-ref},
a subclass of
~pytest.PytestDeprecationWarning{.interpreted-text role="class"},instead of
PytestDeprecationWarning{.interpreted-text role="class"} directly.See
backwards-compatibility{.interpreted-text role="ref"} for more details.#7864: Improved error messages when parsing warning filters.
Previously pytest would show an internal traceback, which besides being ugly sometimes would hide the cause
of the problem (for example an
ImportErrorwhile importing a specific warning type).#8335: Improved
pytest.approx{.interpreted-text role="func"} assertion messages for sequences of numbers.The assertion messages now dumps a table with the index and the error of each diff.
Example:
#8403: By default, pytest will truncate long strings in assert errors so they don't clutter the output too much,
currently at
240characters by default.However, in some cases the longer output helps, or is even crucial, to diagnose a failure. Using
-vwillnow increase the truncation threshold to
2400characters, and-vvor higher will disable truncation entirely.#8509: Fixed issue where
unittest.TestCase.setUpClass{.interpreted-text role="meth"} is not called when a test has [/]{.title-ref} in its name since pytest 6.2.0.This refers to the path part in pytest node IDs, e.g.
TestClass::test_itin the node IDtests/test_file.py::TestClass::test_it.Now, instead of assuming that the test name does not contain
/, it is assumed that test path does not contain::. We plan to hopefully make both of these work in the future.#8803: It is now possible to add colors to custom log levels on cli log.
By using
add_color_level <_pytest.logging.add_color_level>{.interpreted-text role="func"} from apytest_configurehook, colors can be added:See
log_colors{.interpreted-text role="ref"} for more information.#8822: When showing fixture paths in [--fixtures]{.title-ref} or [--fixtures-by-test]{.title-ref}, fixtures coming from pytest itself now display an elided path, rather than the full path to the file in the [site-packages]{.title-ref} directory.
#8898: Complex numbers are now treated like floats and integers when generating parameterization IDs.

faulthandlersupport would not dump traceback on crashesif the
faulthandler{.interpreted-text role="mod"} module was already enabled during pytest startup (usingpython -X dev -m pytestfor example).#8317: Fixed an issue where illegal directory characters derived from

Class.from_parentso it forwards extra keyword arguments to the constructor.#8377: The test selection options
pytest -kandpytest -mnow support matchingnames containing forward slash (
/) characters.#8384: The
@pytest.mark.skipdecorator now correctly handles its arguments. When thereasonargument is accidentally given both positional and as a keyword (e.g. because it was confused withskipif), aTypeErrornow occurs. Before, such tests were silently skipped, and the positional argument ignored. Additionally,reasonis now documented correctly as positional or keyword (rather than keyword-only).#8394: Use private names for internal fixtures that handle classic setup/teardown so that they don't show up with the default
--fixturesinvocation (but they still show up with--fixtures -v).#8456: The
required_plugins{.interpreted-text role="confval"} config option now works correctly when pre-releases of plugins are installed, rather than falsely claiming that those plugins aren't installed at all.#8464:
-c <config file>now also properly definesrootdiras the directory that contains<config file>.#8503:
pytest.MonkeyPatch.syspath_prepend{.interpreted-text role="meth"} no longer fails whensetuptoolsis not installed.It now only calls
pkg_resources.fixup_namespace_packages{.interpreted-text role="func"} ifpkg_resourceswas previously imported, because it is not needed otherwise.#8548: Introduce fix to handle precision width in
log-cli-formatin turn to fix output coloring for certain formats.#8796: Fixed internal error when skipping doctests.
#8983: The test selection options
pytest -kandpytest -mnow support matching names containing backslash ([\]{.title-ref}) characters.Backslashes are treated literally, not as escape characters (the values being matched against are already escaped).
#8990: Fix [pytest -vv]{.title-ref} crashing with an internal exception [AttributeError: 'str' object has no attribute 'relative_to']{.title-ref} in some cases.
#9077: Fixed confusing error message when
request.fspath/request.pathwas accessed from a session-scoped fixture.#9131: Fixed the URL used by
--pastebinto use bpa.st.#9163: The end line number and end column offset are now properly set for rewritten assert statements.
#9169: Support for the
filesAPI fromimportlib.resourceswithin rewritten files.#9272: The nose compatibility module-level fixtures [setup()]{.title-ref} and [teardown()]{.title-ref} are now only called once per module, instead of for each test function.
They are now called even if object-level [setup]{.title-ref}/[teardown]{.title-ref} is defined.

#7530: The

--strictand make it an encompassing flag for all strictnessrelated options (
--strict-markersand--strict-configat the moment, more might be introduced in the future).#7988: The

#5299: pytest now warns about unraisable exceptions and unhandled thread exceptions that occur in tests on Python>=3.8.
See unraisable for more information.
#7425: New pytester fixture, which is identical to testdir but its methods return pathlib.Path when appropriate instead of
py.path.local.This is part of the movement to use pathlib.Path objects internally, in order to remove the dependency to
pyin the future.Internally, the old Testdir <_pytest.pytester.Testdir> is now a thin wrapper around Pytester <_pytest.pytester.Pytester>, preserving the old interface.
#7695: A new hook was added, pytest_markeval_namespace which should return a dictionary.
This dictionary will be used to augment the "global" variables available to evaluate skipif/xfail/xpass markers.
Pseudo example
conftest.py:test_func.py:#8006: It is now possible to construct a ~pytest.MonkeyPatch object directly as
pytest.MonkeyPatch(),in cases when the monkeypatch fixture cannot be used. Previously some users imported it
from the private _pytest.monkeypatch.MonkeyPatch namespace.
Additionally, MonkeyPatch.context <pytest.MonkeyPatch.context> is now a classmethod,
and can be used as
with MonkeyPatch.context() as mp: .... This is the recommended way to useMonkeyPatchdirectly, since unlike themonkeypatchfixture, an instance created directlyis not
undo()-ed automatically.Improvements
#1265: Added an
__str__implementation to the ~pytest.pytester.LineMatcher class which is returned frompytester.run_pytest().stdoutand similar. It returns the entire output, like the existingstr()method.#2044: Verbose mode now shows the reason that a test was skipped in the test's terminal line after the "SKIPPED", "XFAIL" or "XPASS".
#7469 The types of builtin pytest fixtures are now exported so they may be used in type annotations of test functions.
The newly-exported types are:
pytest.FixtureRequestfor the request fixture.pytest.Cachefor the cache fixture.pytest.CaptureFixture[str]for the capfd and capsys fixtures.pytest.CaptureFixture[bytes]for the capfdbinary and capsysbinary fixtures.pytest.LogCaptureFixturefor the caplog fixture.pytest.Pytesterfor the pytester fixture.pytest.Testdirfor the testdir fixture.pytest.TempdirFactoryfor the tmpdir_factory fixture.pytest.TempPathFactoryfor the tmp_path_factory fixture.pytest.MonkeyPatchfor the monkeypatch fixture.pytest.WarningsRecorderfor the recwarn fixture.Constructing them is not supported (except for MonkeyPatch); they are only meant for use in type annotations.
Doing so will emit a deprecation warning, and may become a hard-error in pytest 7.0.
Subclassing them is also not supported. This is not currently enforced at runtime, but is detected by type-checkers such as mypy.
#7527: When a comparison between namedtuple <collections.namedtuple> instances of the same type fails, pytest now shows the differing field names (possibly nested) instead of their indexes.
#7615: Node.warn <_pytest.nodes.Node.warn> now permits any subclass of Warning, not just PytestWarning <pytest.PytestWarning>.
#7701: Improved reporting when using
--collected-only. It will now show the number of collected tests in the summary stats.#7710: Use strict equality comparison for non-numeric types in pytest.approx instead of
raising TypeError.
This was the undocumented behavior before 3.7, but is now officially a supported feature.

TestReport.longrepris now always an instance ofReprExceptionInfo. Previously it was astrwhen a test failed withpytest.fail(..., pytrace=False).#5965: symlinks are no longer resolved during collection and matching conftest.py files with test file paths.
Resolving symlinks for the current directory and during collection was introduced as a bugfix in 3.9.0, but it actually is a new feature which had unfortunate consequences in Windows and surprising results in other platforms.
The team decided to step back on resolving symlinks at all, planning to review this in the future with a more solid solution (see discussion in
#6523 for details).
This might break test suites which made use of this feature; the fix is to create a symlink

The --strict-config flag has been added to treat these warnings as errors.
#6906: Added --code-highlight command line option to enable/disable code highlighting in terminal output.
#7245: New
--import-mode=importliboption that uses importlib to import test modules.Traditionally pytest used
__import__while changingsys.pathto import test modules (whichalso changes
sys.modulesas a side-effect), which works but has a number of drawbacks, like requiring test modulesthat don't live in packages to have unique names (as they need to reside under a unique name in
sys.modules).--import-mode=importlibuses more fine grained import mechanisms fromimportlibwhich don'trequire pytest to change
sys.pathorsys.modulesat all, eliminating much of the drawbacksof the previous mode.
We intend to make
--import-mode=importlibthe default in future versions, so users are encouragedto try the new mode and provide feedback (both positive or negative) in issue #7245.
You can read more about this option in the documentation.
#7305: New
required_pluginsconfiguration option allows the user to specify a list of plugins, including version information, that are required for pytest to run. An error is raised if any required plugins are not found when running pytest.Improvements
#4375: The
pytestcommand now suppresses theBrokenPipeErrorerror message thatis printed to stderr when the output of
pytestis piped and and the pipe isclosed by the piped-to program (common examples are
lessandhead).#4391: Improved precision of test durations measurement.
CallInfoitems now have a new<CallInfo>.durationattribute, created usingtime.perf_counter(). This attribute is used to fill the<TestReport>.durationattribute, which is more accurate than the previous<CallInfo>.stop - <CallInfo>.start(as these are based ontime.time()).#4675: Rich comparison for dataclasses and attrs-classes is now recursive.
#6285: Exposed the pytest.FixtureLookupError exception which is raised by request.getfixturevalue()
(where request is a FixtureRequest fixture) when a fixture with the given name cannot be returned.
#6433: If an error is encountered while formatting the message in a logging call, for
example
logging.warning("oh no!: %s: %s", "first")(a second argument ismissing), pytest now propagates the error, likely causing the test to fail.
Previously, such a mistake would cause an error to be printed to stderr, which
is not displayed by default for passing tests. This change makes the mistake
visible during testing.
You may supress this behavior temporarily or permanently by setting
logging.raiseExceptions = False.#6817: Explicit new-lines in help texts of command-line options are preserved, allowing plugins better control
of the help displayed to users.
#6940: When using the
--durationoption, the terminal message output is now more precise about the number and duration of hidden items.#6991: Collected files are displayed after any reports from hooks, e.g. the status from
--lf.#7091: When
fdcapturing is used, through--capture=fdor thecapfdandcapfdbinaryfixtures, and the file descriptor (0, 1, 2) cannot beduplicated, FD capturing is still performed. Previously, direct writes to the
file descriptors would fail or be lost in this case.
#7119: Exit with an error if the
--basetempargument is empty, is the current working directory or is one of the parent directories.This is done to protect against accidental data loss, as any directory passed to this argument is cleared.
#7128: pytest --version now displays just the pytest version, while pytest --version --version displays more verbose information including plugins. This is more consistent with how other tools show --version.
#7133: caplog.set_level() <_pytest.logging.LogCaptureFixture.set_level> will now override any log_level set via the CLI or configuration file.
#7159: caplog.set_level() <_pytest.logging.LogCaptureFixture.set_level> and caplog.at_level() <_pytest.logging.LogCaptureFixture.at_level> no longer affect
the level of logs that are shown in the Captured log report report section.
#7348: Improve recursive diff report for comparison asserts on dataclasses / attrs.
#7385:
--junitxmlnow includes the exception cause in themessageXML attribute for failures during setup and teardown.Previously:

Bug Fixes
#1120: Fix issue where directories from tmpdir are not removed properly when multiple instances of pytest are running in parallel.
#4583: Prevent crashing and provide a user-friendly error when a marker expression (-m) invoking of eval raises any exception.
#4677: The path shown in the summary report for SKIPPED tests is now always relative. Previously it was sometimes absolute.
#5456: Fix a possible race condition when trying to remove lock files used to control access to folders
created by tmp_path and tmpdir.
#6240: Fixes an issue where logging during collection step caused duplication of log
messages to stderr.
#6428: Paths appearing in error messages are now correct in case the current working directory has
changed since the start of the session.
#6755: Support deleting paths longer than 260 characters on windows created inside tmpdir.
#6871: Fix crash with captured output when using capsysbinary.
#6909: Revert the change introduced by #6330, which required all arguments to
@pytest.mark.parametrizeto be explicitly defined in the function signature.The intention of the original change was to remove what was expected to be an unintended/surprising behavior, but it turns out many people relied on it, so the restriction has been reverted.
#6910: Fix crash when plugins return an unknown stats while using the
--reportlogoption.#6924: Ensure a
unittest.IsolatedAsyncioTestCaseis actually awaited.#6925: Fix TerminalRepr instances to be hashable again.
#6947: Fix regression where functions registered with unittest.TestCase.addCleanup were not being called on test failures.
#6951: Allow users to still set the deprecated
TerminalReporter.writerattribute.#6956: Prevent pytest from printing ConftestImportFailure traceback to stdout.
#6991: Fix regressions with --lf filtering too much since pytest 5.4.
#6992: Revert "tmpdir: clean up indirection via config for factories" #6767 as it breaks pytest-xdist.
#7061: When a yielding fixture fails to yield a value, report a test setup error instead of crashing.
#7076: The path of file skipped by
@pytest.mark.skipin the SKIPPED report is now relative to invocation directory. Previously it was relative to root directory.#7110: Fixed regression:
asyncbase.TestCasetests are executed correctly again.#7126:
--setup-shownow doesn't raise an error when a bytes value is used as aparametrizeparameter when Python is called with the
-bbflag.#7143: Fix pytest.File.from_parent so it forwards extra keyword arguments to the constructor.
#7145: Classes with broken
__getattribute__methods are displayed correctly during failures.#7150: Prevent hiding the underlying exception when
ConfTestImportFailureis raised.#7180: Fix
_is_setup_pyfor files encoded differently than locale.#7215: Fix regression where running with
--pdbwould call unittest.TestCase.tearDown for skipped tests.#7253: When using
pytest.fixtureon a function directly, as inpytest.fixture(func),if the
autouseorparamsarguments are also passed, the function is no longerignored, but is marked as a fixture.
#7360: Fix possibly incorrect evaluation of string expressions passed to
pytest.mark.skipifandpytest.mark.xfail,in rare circumstances where the exact same string is used but refers to different global values.
#7383: Fixed exception causes all over the codebase, i.e. use raise new_exception from old_exception when wrapping an exception.
