Removals and backward incompatible breaking changes

#14716: -c now raises a usage error for a path that does not exist, is a directory, or is in a format pytest has no loader for. Such paths were previously either ignored or reported as an unhandled FileNotFoundError.
#8593: The indirect, ids and scope arguments of Metafunc.parametrize() <pytest.Metafunc.parametrize> -- and therefore of @pytest.mark.parametrize <pytest.mark.parametrize ref> -- are now keyword-only.

Passing them positionally was a common source of confusing errors, e.g. parametrize("arg1", "arg2", [(1, 2)]) made the argvalues land in indirect and failed with indirect fixture '(1, 2)' doesn't exist; such mistakes now fail with an understandable TypeError. The type annotations have always declared these arguments as keyword-only.
#993: Plugin import failures at startup are now reported and classified instead of escaping as a raw traceback with the accidental exit code 1:
- a plugin that cannot be found -- via -p, pytest_plugins or PYTEST_PLUGINS -- exits with pytest.ExitCode USAGE_ERROR (4), like a conftest.py that fails to import;
- a plugin that is found but raises while importing -- including a broken pytest11 entry point or a missing plugin dependency -- exits with pytest.ExitCode INTERNAL_ERROR (3), with the traceback preserved.
pytest.main now returns these codes instead of raising ImportError. Also fixed an IndexError from pytest's own internals when the plugin raised an exception with no arguments.

Deprecations (removal in next major release)

#14742: The private _pytest.python.CallSpec2 name has been renamed to CallSpec.
The old CallSpec2 alias remains available for now and will be removed in pytest 10 or 11.
#14755: Schedule yield_fixture decorator for removal in pytest 10 or 11.
#14774: Similarly to the deprecation of class-scoped fixtures defined as instance methods in pytest 9.1,
all higher-scoped fixtures (module, package, and session) defined
as instance methods are now deprecated.

They suffer from the same issue the original deprecation only fixed for
class-scoped fixtures, see 10819 and 14011.
#14808: Passing a non-string value to a string-typed ini option now emits a pytest.PytestRemovedIn10Warning. This affects [tool.pytest.ini_options] in pyproject.toml. In pytest 10 this will raise a TypeError, matching the behavior of the corresponding TOML config path.
#7323: Passing bytes to TerminalReporter.write_line() is now deprecated, pass a str instead.

New features

#14743: Full diff: now contains a legend explaining the + & - symbols in diff output.
#2781: When strict_markers is enabled, marker names used in -m expressions are now validated against registered markers.
#6881: Added the parametrize_long_str_id_strategy configuration option to control how long str/bytes parameter values are handled in auto-generated test IDs. Explicit IDs set via ids=[...] or pytest.param(..., id=...) are not affected. Available strategies: short (default, values over 100 chars fall back to argname+index), sha256 (SHA-256 hex digest), legacy (keep full value), and disallow (error requesting explicit IDs).

Improvements in existing functionality

#10745: A RecursionError whose recursion origin cannot be located now shows only the
first and last 10 stack frames, matching what pytest already did when locating
the origin failed outright. Previously the full traceback -- often around a
thousand near-identical frames -- was rendered, which was both slow and
unreadable. Pass --full-trace to see every frame.
#10745: The line numbers of a module's statements are now computed once per traceback
instead of once per traceback entry, which noticeably speeds up rendering
failures raised from large test modules.
#11418: The cached rewritten modules in __pycache__ are now invalidated by a hash of
the source instead of its modification time, using the checked-hash pyc format
from 552.

Timestamps make the cache useless wherever source files get fresh modification
times, most notably in CI: a checkout gives every file a new mtime, so a
restored cache is discarded in full and every test module is rewritten again.
Hashing the source costs roughly 15 microseconds per file and makes the cache
survive that.

Existing timestamp based caches are ignored and rewritten once.
#12624: The pytest_plugins variable and the PYTEST_PLUGINS environment variable now also accept entry point names of installed plugins (e.g. xdist), in addition to importable module names, matching the behavior of the -p command-line option.

As part of this change, plugins specified by entry point name through these mechanisms are now also listed in the plugins: line of the terminal header (12615).

Based on the original implementation by Marcel Telka in 12616.
#12697: Warnings emitted while importing plugins through -p, PYTEST_PLUGINS, or entry point autoloading are now captured, filtered, and reported like other warnings.
#12860: Assertion diffs for dict.items() and dict.keys() comparisons (>=, <=, >, <, ==) now show which items are missing, the same way set comparisons do.
#13354: Node.get_closest_marker <_pytest.nodes.Node.get_closest_marker> now also accepts a ~pytest.MarkDecorator as its default, for example item.get_closest_marker("foo", pytest.mark.foo(1)), and returns the wrapped ~pytest.Mark.

Previously the only way to build a default was to instantiate ~pytest.Mark directly, which is private and warns.
#13369: Improved the error from pytest.RunResult.assert_outcomes when a plugin changes or removes pytest's standard terminal summary, and documented how to isolate output-changing plugins.
#13431: Exposed pytest.ParameterSet as the type of the return value of pytest.param().
This can be used in type annotations and isinstance checks.
#13564: Issue a warning when fixtures are wrapped with a decorator that prevents
correct discovery, including @classmethod above @pytest.fixture and
@staticmethod above @pytest.fixture. Put @pytest.fixture above
those decorators on test classes.
#14164: Exposed pytest.Approx as the type of the return value of pytest.approx().
This can be used in type annotations and isinstance checks.
#14463: Assertion diffs for mappings now match up keys the way the compared mappings match them themselves.

Key comparison goes through the mappings' key views instead of plain sets of their keys, so a mapping
with its own notion of key equivalence, such as case-insensitive header mappings, no longer
reports its common keys as missing on either side.
#14523: Large assertion comparison diffs are now built lazily and capped to the
truncation budget, so a huge diff is no longer formatted in full just to
be truncated. As a consequence, the truncation footer no longer
reports the exact number of hidden lines.
#14687: The default fd-level output capturing (--capture=fd) now skips reading the capture buffer for tests which produce no output, reducing per-test overhead in large test suites.
#14724: --no-summary now only applies directly to pytest's own summary.

The flag no longer skips the pytest_terminal_summary hook, so third-party
plugins (for example coverage) can still write their terminal summaries.
#14751: parser.addini <pytest.Parser.addini> now also accepts type expressions for its type argument, in addition to the existing string tags: the plain Python types str, bool, int, float, a Literal of strings, and unions of these (for example int | str or int | Literal["auto"]).
#14754: pytest.approx() now rejects infinite relative tolerances for datetime.timedelta values with a clear ValueError instead of raising OverflowError.
#14791: The junit_family, junit_logging, junit_duration_report, console_output_style, empty_parameter_set_mark, assertion_text_diff_style and tmp_path_retention_policy configuration options are now registered with the set of values they accept: an invalid value now fails with a clean usage error instead of being silently ignored or crashing later, and pytest --help lists the accepted values.

config.getini <pytest.Config.getini> now raises pytest.UsageError instead of TypeError or ValueError when the value read from the configuration file does not match the registered type, so a bad value is always reported as a short usage error message instead of an internal error traceback. Asking for an option name that was never registered still raises ValueError.
#15006: pytest.approx now emits pytest.PytestApproxDecimalToleranceWarning when a rel or abs tolerance is given as a float that cannot be represented exactly for a ~decimal.Decimal comparison, since such a tolerance is widened to the float's exact binary value.
#14675, #14953, #15153, #15132: The truncation_limit_lines, truncation_limit_chars, max_warnings, verbosity_assertions, verbosity_test_cases, verbosity_subtests, tmp_path_retention_count, log_level, log_cli_level, log_file_level,log_auto_indent and faulthandler_timeout configuration options now accept native integer (and, for log_auto_indent, boolean) values in TOML configuration files, while still accepting strings for backward compatibility.
log_file_mode now reports invalid values as a usage error.
#15254: tmp_path and TempPathFactory.mktemp <pytest.TempPathFactory.mktemp> no longer list the whole base temporary directory on every call, which made sessions with many temporary directories quadratically slow. Numbers are now handed out from a per-prefix counter, skipping names that already exist.
#4569: Node.add_marker <_pytest.nodes.Node.add_marker> now stores a ~pytest.Mark in node.keywords, matching what marks applied during collection store. Previously it stored a ~pytest.MarkDecorator.
#9436: Avoided formatting tracebacks for tests marked with xfail(run=False).

Bug fixes

#10128: Configured warning filters now apply to warnings emitted by pytest_configure hooks.
#10210: pytest.approx now raises a TypeError for any nested container, not
only for one of the same type as its parent. Previously approx([{"k": 1}])
and approx({"k": [1]}) were accepted and then compared unequal to every
value, silently ignoring the tolerance, while approx([[1]]) correctly
reported that nesting is unsupported.
#10644: monkeypatch.setattr() no longer leaves a new entry in the instance __dict__ when it patches an attribute that the instance inherits from its class.

Previously undo() assigned the inherited value onto the instance, which shadowed the class attribute -- permanently freezing the result for descriptors that resolve dynamically.
#1139: Fixed tracebacks showing ??? instead of source lines for code compiled with a filename relative to a directory other than the current working directory -- e.g. compiled Cython modules, when running pytest from a subdirectory of the project root.
The source lookup now falls back to searching sys.path for such filenames, as the standard traceback module does.
#11502: The rootdir is no longer derived from a configuration file that is not a regular file, such as --config-file=/dev/null.
#11783: Plugins installed in editable mode (660) are marked for assertion rewriting again.

Such installs do not record the package's Python files in the distribution metadata, so pytest found nothing to rewrite and assertions inside the plugin lost their introspection. The plugin's entry point is now used to locate the package in that case.
#11933: pytest.warns no longer re-emits unmatched warnings with module="warnings", which caused module-based warning filters to be applied to the wrong warnings. Since warnings.WarningMessage does not record the module a warning was emitted with, re-emitted warnings now use the standard warnings.warn_explicit default of deriving the module from the warning's filename.
#12175: ExceptionInfo.exconly(tryshort=True) <pytest.ExceptionInfo.exconly> now strips the AssertionError: prefix of failed assert statements for ~pytest.ExceptionInfo objects created by pytest.raises, and failures inside unittest.TestCase.subTest report the same short crash line as regular tests.
#12223: The message attribute of <failure> and <error> elements in --junitxml reports is now shortened to whole lines within 500 characters. When something is dropped, it ends with a note pointing to the element text, which still holds the full report. Previously, very verbose assertion output (e.g. with -vv) produced attributes tens of thousands of characters long, which some XML parsers fail on.
#12307: Fixed truncation of long collections (lists, dicts, sets, etc.) in the "message" part of failed assertions (as in assert condition, msg) when using -vv: the message now uses the same unlimited repr as the rest of the assertion output, instead of eliding collection elements with ....
#12824: Custom command-line options now fail with a clear error when their implicit
destination conflicts with an existing option, avoiding silent overrides of
built-in options such as -k.
#13292: Fixed a stale rewritten module being used when a test file is modified twice
within the same second without changing its size -- the pyc header could only
record whole-second timestamps. The cache is now keyed on a hash of the source.
#14036: __tracebackhide__ is now respected in ExceptionGroup tracebacks, both for the group itself and for its sub-exceptions.
#14189: Nested usage of caplog.filtering <pytest.LogCaptureFixture.filtering> no longer removes filters early if they were already present.
#14412: Fixed incorrect timing information for subtests and parent tests when console_output_style = "times".
#14445: Assertion rewriting no longer evaluates walrus operator (:=) expressions more than once, which reported results the test never computed when the expression had side effects.

An operand evaluated before a later walrus is now reported with the value it actually saw, so assert value != identity(value := value.lower()) keeps Python's left-to-right order.
#14552: Fixed stale co_filename values after a test module or directory is moved. Assertion-rewrite caches are reused when the source hash still matches, and in-memory code objects are pointed at the current path.
#14586: Negative values passed to log_auto_indent now correctly fall back to no indentation, matching the documented behavior.
#14619: Fixed a crash in pytest.mark.parametrize when a non-sequence value is passed for a parameter set. It now provides a clear error message during collection.
#14635: Fixed fixture resolution failures when specifying multiple test paths on the command line that share common parent directories. Parametrized fixtures defined in a conftest.py could be silently dropped depending on the order of the specified paths.
#14637: Pytest now correctly skips identical trailing characters in assertion text diffs even when the compared strings differ at the beginning.
#14638: Top-level options in pytest.toml and .pytest.toml files now raise an error instead of being silently ignored when no [pytest] table is present.
#14683: Fixed a regression in pytest 9.1 where a conftest.py located in the rootdir was no longer visible to tests and doctests collected from outside the rootdir (for example when passing a parent directory of the rootdir as a collection argument, or setting --rootdir to a subdirectory).

As a result, fixtures defined in such a conftest -- including doctest_namespace injections -- were not available, causing errors such as NameError in doctests.
#14700: Fixed an internal error on Python 3.12 when a doctest on a fixture-decorated function was skipped.
#14705: TOML configuration files passed via -c now also read their configuration from the [pytest] table, the one pytest's own configuration files use. The [tool.pytest] and [tool.pytest.ini_options] tables such files were previously restricted to keep working; using both styles in one file is an error.
#14828: Exception groups raised from another exception now print their cause chain only once in the traceback output.
#14864: Fixed collection on Windows collecting the whole suite instead of the given path, on file systems which do not support file IDs (st_ino is 0 for every file, as seen for example on sshfs-win/WinFsp mounts).
#14884: Cache.get(), Cache.set() and Cache.mkdir() now reject keys that resolve outside the cache directory, and --cache-show ignores glob matches outside it.
#14909: Fixed MonkeyPatch.delattr <pytest.MonkeyPatch.delattr>, MonkeyPatch.setitem <pytest.MonkeyPatch.setitem> and MonkeyPatch.delitem <pytest.MonkeyPatch.delitem> recording a stale undo entry when the underlying mutation failed, which could cause spurious errors during teardown. The undo entry is now recorded only after the mutation succeeds, matching the behavior of MonkeyPatch.setattr <pytest.MonkeyPatch.setattr>.
#14912: ~pytest.PytestWarning instances defined in _pytest.deprecated are no longer reused across warnings.warn calls, so warnings raised as errors (e.g. with -W error) no longer accumulate stale traceback frames from previous raises.
#14942: Fixed a regression in 9.1.0 that made collection very slow (quadratic) when many fixtures are defined with the same name.
This can happen particularly when many tests are defined in separate classes which inherit from a base class which defines fixtures (the fixtures are repeated per class).
#15005: pytest.approx no longer treats finite ~decimal.Decimal values outside the float range (such as Decimal("1e400")) as infinite, which made in-tolerance comparisons fail.
#15006: Restored the tolerance shown by pytest.approx for ~decimal.Decimal values, which since 9.0 displayed ??? for the default tolerance and reported the raw rel ratio instead of the absolute tolerance actually compared against.
#15006: The failure message for pytest.approx comparisons of ~decimal.Decimal collections no longer reports Max absolute difference: -inf, or crashes for mappings, when the decimal.FloatOperation trap is set.
#15006: pytest.approx no longer raises AttributeError when comparing numpy.ndarray instances with object dtype, such as arrays of ~decimal.Decimal.
#15032: Help texts for command-line options and configuration options now keep their indentation
and blank lines. Previously each line was stripped before wrapping, so a wrapped
list item was indistinguishable from a new one and blank lines were dropped; configuration
option help lost its line breaks entirely.
#15043: Cache writes now emit pytest.PytestCacheWarning when writing or closing the cache file fails, consistent with errors opening the file.
#15052: Fixed possible off-by-one line numbers in --fixtures and --fixtures-per-test output.
#15145: With console_output_style set to times, durations just below a unit boundary are now shown in the next unit (e.g. 1.000ms instead of 1000.0us).
#15172: Assertion diffs now pretty-print the built-in frozendict (Python 3.15+) across multiple lines, similarly to how dict is displayed.
#4569: -k no longer matches attributes that end up in a test function's __dict__ without being meant as keywords, such as pytest's own pytestmark attribute and the bookkeeping left behind by functools.wraps and functools.lru_cache.
#6750: Fix fixture argument discovery for custom collectors that pass bound methods to pytest.Function.
#6997: XFAIL reports from teardown phases now include the phase in the short test
summary.
#7940: Fixed cleanup of temporary directories failing when subdirectories have their execute permission removed.
#8321: Fixed exception chains being duplicated in the traceback output when an exception in the chain (__cause__/__context__) has no traceback of its own, and that exception is itself linked to further exceptions.
#8914: Tests parametrized with higher-than-function scope are now reordered by
parameter value rather than by parameter index, so that items using equal
parameter values are grouped together and share a single fixture setup, even
when they are parametrized by separate @pytest.mark.parametrize <pytest.mark.parametrize ref>
calls. Previously, an expensive higher-scoped fixture could be set up and torn
down repeatedly for the same parameter value.

Unhashable parameter values (e.g. dicts) keep the previous index-based
grouping behavior.

As a consequence, the order in which parametrized tests run may change
(fixture setup/teardown counts can only decrease, not increase).
#9924: Fixed doctest option flags leaking between docstrings after a failure, skip, or expected failure.

Improved documentation

#10721: Replaced setup.py usage with pyproject.toml in writing-plugins.
#12658: Moved the fixture setup and finalizer hooks to the test running hooks section in the reference documentation.
#12857: Documented how --confcutdir affects initial conftest.py discovery.
#14157: Added the pytest-flakefighters plugin to the list of flaky test plugins in plugins.rst.
Added flaky test papers published on the Test FLARE project to the list of flaky papers in plugins.rst.
#15127: Added guidance on typing yield fixtures, including annotating fixture functions with their generator type and fixture consumers with the yielded value type.
#15242: The installation instructions <installation> and install-package-with-pip now show how to install pytest into a virtual environment with venv and pip, uv or virtualenv, and explain the externally-managed-environment error.
#4569: pytest --help, the -k reference entry and select-tests no longer describe -k as a Python expression matched against test names only; keyword expressions now shows marker names being matched as well. The examples that looked up a marker use Node.get_closest_marker <_pytest.nodes.Node.get_closest_marker> rather than item.keywords.
#9614: Clarified that session.items and session.testscollected exclude deselected tests in the pytest_collection documentation.

Packaging updates and notes for downstreams

#11680: Source archives of arbitrary commits -- the tarballs GitHub serves under
/archive/, not just the ones for tags -- can now be built into an sdist or a
wheel with a correct version. A .git_archival.txt file, expanded by git archive via export-subst, carries the describe output that
setuptools-scm would otherwise have to ask git for.

The archival file deliberately omits ref-names. Recording it would make the
content of an archive -- and therefore its checksum -- change whenever a branch
that points at the archived commit is moved afterwards, which is how the
equivalent tarballs of tagged releases became unstable for other projects.
Describe output alone depends only on the commit and on the tags reachable from
it.

The archival file is not shipped in the sdist -- an sdist carries its version
in its metadata, and the template is only ever expanded by git archive.

Building pytest from a git checkout now requires setuptools-scm >= 10.1.
#9236: pluggy>=1.6 is now required.

Older pluggy versions stopped running the remaining hook wrapper teardowns once an
old-style hookwrapper raised in its own teardown. The logging plugin's wrapper was
left suspended, and when it was finalised later it detached the handler that
caplog of a subsequent test was recording through, so that test saw no records.

Contributor-facing changes

#14813: Added a systematic coverage matrix for assertion rewriting.
#14921: Added scripts/diff-assert-rewrite.py, which diffs the assert-rewritten form of a snippet between the plain source, this checkout and released pytest versions.
#15190: Fixed the documentation build with Pluggy 1.7 by ignoring a reference to its undocumented DistFacade compatibility class.

Miscellaneous internal changes

#13888: FixtureRequest.node <pytest.FixtureRequest.node> is now explicitly annotated as returning Any, so strict pyright no longer reports it as Unknown. The return type stays deliberately broad, see 13888.
#14758: Internal node ids (the ::-separated strings identifying collected items, e.g. path/to/test_file.py::TestClass::test_method[param]) are now represented internally by a single structured ~_pytest.nodeid.NodeId dataclass instead of being repeatedly re-parsed as plain strings. The public nodeid: str attribute on nodes and reports is unchanged and remains fully backward compatible for plugins.

⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

any of the package files in this branch needs updating, or
the branch becomes conflicted, or
you click the rebase/retry checkbox if found above, or
you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: pyproject.toml

Artifact update for ty resolved to version 0.0.94, which is a pending version that has not yet passed the Minimum Release Age threshold.
Renovate was attempting to update to 0.0.93
This is (likely) not a bug in Renovate, but due to the way your project pins dependencies, _and_ how Renovate calls your package manager to update them.
Until Renovate supports specifying an exact update to your package manager (https://github.com/renovatebot/renovate/issues/41624), it is recommended to directly pin your dependencies (with `rangeStrategy=pin` for apps, or `rangeStrategy=widen` for libraries)
