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.

py

provides a vendored copy ofpy.error
andpy.path
modules but will use thepy
library if it is installed. If you need otherpy.*

library separately, otherwise it can usually be removed as a dependency.#4562: Deprecate configuring hook specs/impls using attributes/marks.
Instead use :py

list[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}.

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

#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

{.interpreted-text role="class"} to skip collection oftests during the pytest collection phase is reverted - this is now a supported

#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

pytest 7.0.0rc1 (2021-12-06)
Breaking Changes
#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.

Following our plan to remove deprecated features with as little disruption as
possible, all warnings of type

.There was no deprecation period for this change (sorry!).
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
cache.mkdir() <pytest.Cache.mkdir>
{.interpreted-text role="meth"}, which is similar to the existingcache.makedir() <pytest.Cache.makedir>
{.interpreted-text role="meth"},but returns a
pathlib.Path
{.interpreted-text role="class"} instead of a legacypy.path.local
.Added a
paths
type toparser.addini() <pytest.Parser.addini>
{.interpreted-text role="meth"},as in
parser.addini("mypaths", "my paths", type="paths")
,which is similar to the existing
pathlist
,but returns a list of
pathlib.Path
{.interpreted-text role="class"} instead of legacypy.path.local
.#7469: The types of objects used in pytest's API are now exported so they may be used in type annotations.
The newly-exported types are:
pytest.Config
forConfig <pytest.Config>
{.interpreted-text role="class"}.pytest.Mark
formarks <pytest.Mark>
{.interpreted-text role="class"}.pytest.MarkDecorator
formark decorators <pytest.MarkDecorator>
{.interpreted-text role="class"}.pytest.MarkGenerator
for thepytest.mark <pytest.MarkGenerator>
{.interpreted-text role="class"} singleton.pytest.Metafunc
for themetafunc <pytest.MarkGenerator>
{.interpreted-text role="class"} argument to thepytest_generate_tests
{.interpreted-text role="hook"} hook.pytest.CallInfo
for theCallInfo <pytest.CallInfo>
{.interpreted-text role="class"} type passed to various hooks.pytest.PytestPluginManager
forPytestPluginManager <pytest.PytestPluginManager>
{.interpreted-text role="class"}.pytest.ExceptionInfo
for theExceptionInfo <pytest.ExceptionInfo>
{.interpreted-text role="class"} type returned frompytest.raises
{.interpreted-text role="func"} and passed to various hooks.pytest.Parser
for theParser <pytest.Parser>
{.interpreted-text role="class"} type passed to thepytest_addoption
{.interpreted-text role="hook"} hook.pytest.OptionGroup
for theOptionGroup <pytest.OptionGroup>
{.interpreted-text role="class"} type returned from theparser.addgroup <pytest.Parser.getgroup>
{.interpreted-text role="func"} method.pytest.HookRecorder
for theHookRecorder <pytest.HookRecorder>
{.interpreted-text role="class"} type returned from~pytest.Pytester
{.interpreted-text role="class"}.pytest.RecordedHookCall
for theRecordedHookCall <pytest.HookRecorder>
{.interpreted-text role="class"} type returned from~pytest.HookRecorder
{.interpreted-text role="class"}.pytest.RunResult
for theRunResult <pytest.RunResult>
{.interpreted-text role="class"} type returned from~pytest.Pytester
{.interpreted-text role="class"}.pytest.LineMatcher
for theLineMatcher <pytest.RunResult>
{.interpreted-text role="class"} type used in~pytest.RunResult
{.interpreted-text role="class"} and others.pytest.TestReport
for theTestReport <pytest.TestReport>
{.interpreted-text role="class"} type used in various hooks.pytest.CollectReport
for theCollectReport <pytest.CollectReport>
{.interpreted-text role="class"} type used in various hooks.Constructing most of them directly is not supported; they are only meant for use in type annotations.
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.
#7856:
--import-mode=importlib <import-modes>
{.interpreted-text role="ref"} now works with features thatdepend on modules being on :py
sys.modules
{.interpreted-text role="data"}, such aspickle
{.interpreted-text role="mod"} anddataclasses
{.interpreted-text role="mod"}.#8144: The following hooks now receive an additional
pathlib.Path
argument, equivalent to an existingpy.path.local
argument:pytest_ignore_collect
{.interpreted-text role="hook"} - Thecollection_path
parameter (equivalent to existingpath
parameter).pytest_collect_file
{.interpreted-text role="hook"} - Thefile_path
parameter (equivalent to existingpath
parameter).pytest_pycollect_makemodule
{.interpreted-text role="hook"} - Themodule_path
parameter (equivalent to existingpath
parameter).pytest_report_header
{.interpreted-text role="hook"} - Thestart_path
parameter (equivalent to existingstartdir
parameter).pytest_report_collectionfinish
{.interpreted-text role="hook"} - Thestart_path
parameter (equivalent to existingstartdir
parameter).::: {.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).:::
#8251: Implement
Node.path
as apathlib.Path
. Both the oldfspath
and this new attribute gets set no matter whetherpath
orfspath
(deprecated) is passed to the constructor. It is a replacement for thefspath
attribute (which represents the same path aspy.path.local
). Whilefspath
is not deprecated yetdue to the ongoing migration of methods like
~_pytest.Item.reportinfo
{.interpreted-text role="meth"}, we expect to deprecate it in a future release.::: {.note}

#8421:
pytest.approx
{.interpreted-text role="func"} now works on~decimal.Decimal
{.interpreted-text role="class"} within mappings/dicts and sequences/lists.#8606: pytest invocations with
--fixtures-per-test
and--fixtures
have been enriched with:--verbose
option.#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
toml
totomli
for 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
plugin-stash
{.interpreted-text role="ref"} for details.#8953:
RunResult <_pytest.pytester.RunResult>
{.interpreted-text role="class"} methodassert_outcomes <_pytest.pytester.RunResult.assert_outcomes>
{.interpreted-text role="meth"} now accepts awarnings
argument to assert the total number of warnings captured.#8954:
--debug
flag now accepts astr
{.interpreted-text role="class"} file to route debug logs into, remains defaulted to [pytestdebug.log]{.title-ref}.#9023: Full diffs are now always shown for equality assertions of iterables when
[CI]{.title-ref} or

#9113:
RunResult <_pytest.pytester.RunResult>
{.interpreted-text role="class"} methodassert_outcomes <_pytest.pytester.RunResult.assert_outcomes>
{.interpreted-text role="meth"} now accepts adeselected
argument to assert the total number of deselected tests.#9114: Added
pythonpath
{.interpreted-text role="confval"} setting that adds listed paths tosys.path
{.interpreted-text role="data"} for the duration of the test session. 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
ImportError
while 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.
