Release Notes

coveragepy/coveragepy (coverage)

v7.15.3

Compare Source

  • Fix: the sysmon core is incompatible with dynamic contexts. Previously, the
    combination would be prevented when read from the coverage.py configuration.
    But using the context API as pytest-cov does, contexts would be silently
    dropped. Now a warning is issued, thanks to Jisang Han <pull 2234_>.
    Closes issue 2200
    .

  • A performance improvement in the low-level line number bookkeeping when
    combining data files, thanks to Kevin Turcios <pull 2239_>_.

  • Performance improvement in HTML reporting by reducing the number of times
    files have to be parsed, thanks to Kevin Turcios <pull 2240_>_.

v7.15.2

Compare Source

  • Fix: one of the performance improvements in 7.15.1 (pull 2215) dramatically
    increased memory use during reporting for large projects. Now we use a
    different approach that is both faster and slimmer than 7.15.0. Fixes issue 2229_.

v7.15.1

Compare Source

  • Fix: in the HTML report with show_contexts enabled, a context label
    containing </script> (for example a parametrized pytest node id) could
    close the inline <script> element in a file page early, injecting markup.
    Context labels are now fully escaped. Thanks, Rajath Mohare <pull 2224_>_.

v7.15.0

Compare Source

  • Since 7.14.0, reporting commands implicitly combine parallel data files. Now
    those commands have a new option --keep-combined to retain the data files
    after combining them instead of the default, which is to delete them.
    Finishes issue 2198_.

  • Fix: the LCOV report would incorrectly count excluded functions as uncovered,
    as described in issue 2205. This is now fixed thanks to Martin Kuntz Jacobsen <pull 2206_>.

  • When running your program, coverage now correctly sets
    yourmodule.__spec__.loader as strongly recommended <--loader--_>,
    avoiding the deprecation warning described in issue 2208
    . Thanks, A5rocks <pull 2209_>_.

  • Fix: with Python 3.10, running with the -I (isolated mode) option didn't
    correctly omit the current directory from the module search path, as
    described in issue 2103. That is now fixed thanks to Ilia Sorokin <pull 2211_>.

  • Fix: the default ... exclusion rule now also matches function bodies
    whose closing return-type bracket is on its own line (for example, after a
    long -> dict[ ... ] annotation that a formatter has split over multiple
    lines). Closes issue 2185, thanks Mengjia Shang <pull 2196_>.

  • Fix: On 3.13t, we incorrectly issued Couldn't import C tracer errors.
    We can't import the C tracer because in 7.14.2 we stopped shipping compiled
    wheels for 3.13t. Thanks, Hugo van Kemenade <pull 2203_>_.

v7.14.2

Compare Source

  • Fix: some messages were being written to stdout, making coverage json -o - useless for capturing JSON output. Now messages are written to stderr,
    fixing issue 2197_.

  • Fix: CoverageData kept one SQLite connection per thread that recorded
    coverage, but never closed them when those threads terminated. On long runs
    with many short-lived threads this leaked one file descriptor per dead
    thread, eventually failing with OSError: [Errno 24] Too many open files.
    Connections belonging to terminated threads are now closed and dropped.
    Fixes issue 2192_.

  • Fix: when using sys.monitoring, we were assuming we could use the
    COVERAGE_ID tool id. But other tools might also assume they could use
    that id. Pre-allocated ids don't really make sense, so now we search for a
    usable one instead. Fixes issue 2187. Thanks, Matthew Lloyd <pull 2198_>.

  • Following the advice of cibuildwheel <no-13t_>_, we no longer distribute
    wheels for Python 3.13 free-threaded.

  • Fix: the HTML report used typographic niceties to make file paths more
    readable by adding a small amount of space around slashes. Those spaces
    interfered with searching the page for file paths of interest. Now the report
    uses CSS to accomplish the same visual tweak so that searches with slashes
    work correctly. Closes issue 2170_.

    branch.

v9.1.1

Compare Source

pytest 9.1.1 (2026-06-19)

Bug fixes

  • #​14220: Fixed a logic bug in pytest.RaisesGroup which would might cause it to display incorrect "It matches FooError() which was paired with BarError" messages.
  • #​14591: Fixed a regression in pytest 9.1.0 which caused overriding a parametrized fixture with an indirect @​pytest.mark.parametrize to fail with "duplicate parametrization of '<fixture name>'".
  • #​14606: Fixed list-item typing errors from mypy in @pytest.mark.parametrize <pytest.mark.parametrize ref> argvalues parameter.
  • #​14608: Fixed a regression in pytest 9.1.0 where conftest.py files located in <invocation dir>/test* were no longer loaded as initial conftests when invoked without arguments.
    This could cause certain hooks (like pytest_addoption) in these files to not fire.

v9.1.0

Compare Source

pytest 9.1.0 (2026-06-13)
Removals and backward incompatible breaking changes
  • #​14533: When using --doctest-modules, autouse fixtures with module, package or session scope that are defined inline in Python test modules (not plugins or conftests) will now possibly execute twice.

    If this is undesirable, move the fixture definition to a conftest.py file if possible.

    Technical explanation for those interested:
    When using --doctest-modules, pytest possibly collects Python modules twice, once as pytest.Module and once as a DoctestModule (depending on the configuration).
    Due to improvements in pytest's fixture implementation, if e.g. the DoctestModule collects a fixture, it is now visible to it only, and not to the Module.
    This means that both need to register the fixtures independently.

Deprecations (removal in next major release)
  • #​10819: Added a deprecation warning for class-scoped fixtures defined as instance methods (without @classmethod). Such fixtures set attributes on a different instance than the test methods use, leading to unexpected behavior. Use @classmethod decorator instead -- by yastcher.

    See 10819 and 14011.

  • #​12882: Calling request.getfixturevalue() <pytest.FixtureRequest.getfixturevalue> during teardown to request a fixture that was not already requested is now deprecated and will become an error in pytest 10.

    See dynamic-fixture-request-during-teardown for details.

  • #​13409: Using non-~collections.abc.Collection iterables (such as generators, iterators, or custom iterable objects) for the argvalues parameter in @pytest.mark.parametrize <pytest.mark.parametrize ref> and metafunc.parametrize <pytest.Metafunc.parametrize> is now deprecated.

    These iterables get exhausted after the first iteration,
    leading to tests getting unexpectedly skipped in cases such as running pytest.main() multiple times,
    using class-level parametrize decorators,
    or collecting tests multiple times.

    See parametrize-iterators for details and suggestions.

  • #​13946: The private config.inicfg attribute is now deprecated.
    Use config.getini() <pytest.Config.getini> to access configuration values instead.

    See config-inicfg for more details.

  • #​14004: Passing baseid to ~pytest.FixtureDef or nodeid strings to fixture registration APIs is now deprecated. These are internal pytest APIs that are used by some plugins.

    Use the node parameter instead for fixture scoping. This enables more robust node-based
    matching instead of string prefix matching.
    If you've used nodeid=None, pass node=session instead.

    This will be removed in pytest 10.

  • #​14335: The method of configuring hooks using markers, deprecated since pytest 7.2, is now scheduled to be removed in pytest 10.
    See hook-markers for more details.

  • #​14434: The --pastebin option is now deprecated.
    The same functionality is now available in an external plugin, pytest-pastebin.
    See pastebin-deprecated for more details.

  • #​14513: The private FixtureDef.has_location attribute is now deprecated and will be removed in pytest 10.
    See fixturedef-has-location-deprecated for details.

  • #​1764: pytest.console_main is now deprecated and will be removed in pytest 10.
    It was never intended for programmatic use; use pytest.main instead.

New features
  • #​12376: Added pytest.register_fixture() to register fixtures using an imperative interface.

    This is an advanced function intended for use by plugins.

    Normally, fixtures should be registered declaratively using the @pytest.fixture <pytest.fixture> decorator.
    Pytest looks for these fixture definitions during the collection phase and registers them automatically.
    For some plugin usecases the declarative interface can be cumbersome or unviable, in which case this imperative interface can be used.

  • #​14023: Added --report-chars long CLI option.

  • #​14371: Added --max-warnings command-line option and max_warnings configuration option to fail the test run when the number of warnings exceeds a given threshold -- by miketheman.

  • #​6757: Added the assertion_text_diff_style configuration option, allowing
    string equality failures to be rendered as separate Left: and Right:
    blocks instead of ndiff output.

  • #​8395: Added support for ~datetime.datetime and ~datetime.timedelta comparisons with pytest.approx. An explicit abs or rel tolerance as a ~datetime.timedelta is required and relative tolerance is not supported for datetime comparisons -- by hamza-mobeen.

Improvements in existing functionality
  • #​11225: pytest.warns now shows "Regex pattern did not match" instead of "DID NOT WARN" when warnings were emitted but the match pattern did not match.

  • #​11295: Improved output of --fixtures-per-test by excluding internal-implementation fixtures generated by @pytest.mark.parametrize and similar.

  • #​13241: pytest.raises, pytest.warns and pytest.deprecated_call now uses ParamSpec for the type hint to the (old and not recommended) callable overload, instead of Any. This allows type checkers to raise errors when passing incorrect function parameters.
    func can now also be passed as a kwarg, which the type hint previously showed as possible but didn't accept.

  • #​13862: Improved the readability of "DID NOT RAISE" error messages by using the exception type's name instead of its repr.

  • #​14026: Added test coverage for compiled regex patterns in pytest.raises match parameter.

  • #​14137: pytest.ScopeName is now public to allow using it in function signatures.

  • #​14342: Marked yield_fixture as deprecated to type checkers using the deprecated decorator. Note it
    has originally been deprecated <yield-fixture-deprecated> in pytest 6.2 already.

  • #​14373: Added type annotations for pytest.approx.

  • #​14430: When using --setup-show, a space is now printed after the test name (and possibly used fixtures), to separate it from the test result.

  • #​14441: Reduced the default number of gc.collect() passes in the unraisableexception plugin from 5 to 1 on CPython, where reference counting makes a single pass sufficient. PyPy retains 5 passes due to object resurrection via __del__. This can noticeably speed up test suites that trigger many pytester runs.

  • #​14461: Improved assertion failure explanations for equality comparisons between mapping objects that are not dict instances.

  • #​14513: The order in which fixture definitions overriding each other are resolved is now determined first by their visibility in the collection tree rather than by the order in which they are registered.

    A fixture defined for a more specific node (e.g. a module or an item) now always takes precedence over one with the same name defined for a more general node (e.g. the session), even when the more general one was registered later.
    Fixtures with non-comparable visibility or the same visibility keep the existing behavior of "last registered wins".
    This change is supposed to only affect plugins which register multiple fixtures programmatically with the same name.

  • #​14524: Add official Python 3.15 support.

  • #​1764: Improved argparse program name to show pytest, python -m pytest, or pytest.main() based on how pytest was invoked, making help and error messages clearer.

  • #​8265: Emit a PytestCollectionWarning when a module-level __getattr__ returns None for pytestmark instead of raising AttributeError.

    Previously this caused a cryptic TypeError: got None instead of Mark error.
    Now pytest issues a helpful warning and continues collecting the module normally.

Bug fixes
  • #​13192: Fixed | (pipe) not being treated as a regex meta-character that needs escaping in pytest.raises(match=...) <pytest.raises>.

  • #​13484: Fixed -W option values being duplicated in Config.known_args_namespace.

  • #​13626: Fixed function-scoped fixture values being kept alive after a test was interrupted by KeyboardInterrupt or early exit,
    allowing them to potentially be released more promptly.

  • #​13784: Fixed capteesys producing doubled output when used with --capture=no (-s).

  • #​13817: Fixed a secondary AttributeError masking the original error when an option argument fails to initialize.

  • #​13884: Fixed rare internal IndexError caused by builtins.compile being overridden in client code.

  • #​13885: Fixed autouse fixtures defined inside a unittest.TestCase class running even when the class is decorated with unittest.skip or unittest.skipIf -- regression since pytest 8.1.0.

  • #​13917: unittest.SkipTest is no longer considered an interactive exception, i.e. pytest_exception_interact is no longer called for it.

  • #​13963: Fixed subtests running with pytest-xdist when their contexts contain objects that are not JSON-serializable.

    Fixes pytest-dev/pytest-xdist#1273.

  • #​14004: Fixed conftest.py fixture scoping when testpaths points outside of the rootdir <rootdir>.

    Previously, fixtures from nested conftest.py files would incorrectly leak to sibling directories
    when using a relative testpaths like ../tests/sdk.

    Conftest fixtures are now parsed during Directory <pytest.Directory> collection, using the Directory node for proper scoping.

  • #​14050: Display dictionary differences in assertion failures using the original key insertion order instead of sorted order.

  • #​14080: fix missing type annotations on Pytester.makepyfile and Pytester.maketxtfile methods.

  • #​14114: An exception from pytest_fixture_post_finalizer no longer prevents fixtures from being torn down, causing additional errors in the following tests.

  • #​14161: Fixed monkeypatch.setattr() <pytest.MonkeyPatch.setattr> leaving a stale entry on the undo stack when the underlying setattr() call fails (e.g. on immutable targets), causing an AttributeError crash during teardown.

  • #​14214: Fixed -v hint in pytest.raises match diff not working because assertion verbosity was not propagated.

  • #​14234: Allow pytest.HIDDEN_PARAM <hidden-param> in @pytest.mark.parametrize(ids=...) <pytest.mark.parametrize ref> typing.

  • #​14248: Fixed direct parametrization causing the static fixture closure (as reflected in request.fixturenames <pytest.FixtureRequest.fixturenames>) to omit fixtures that are requested transitively from overridden fixtures.

  • #​14263: Unraisable exceptions from finalizers are now collected during pytest_unconfigure, before pytest tears down the warning filters installed for the session. Previously the collection ran from a cleanup callback whose order relative to other plugins' cleanups was not guaranteed, so an active error filter could be removed before the exception surfaced and a late resource leak would pass silently. A -W error filter, or any filter matching pytest.PytestUnraisableExceptionWarning, now promotes these exceptions to failures regardless of plugin cleanup order.

  • #​14377: Fixed crash in Config.get_terminal_writer when an assertion fails with the terminalreporter plugin disabled.

  • #​14381: Fixed -V (short form of --version) to properly display the current version.

  • #​14389: Improved pytest.raises(..., match=...) <pytest.raises> failures to suppress the mismatched exception as a cause of the resulting AssertionError.

  • #​14392: Fixed a bug in pytest.raises(match=...) <pytest.raises> "fully escaped" detection, causing the regex diff display to be shown in some instances when the raw string diff display should be shown instead.

  • #​14442: Fixed a regression in pytest 9.0 where --strict-markers and --strict-config specified through addopts were silently ignored.

    Note that when targeting pytest >= 9.0, it's nicer to use strict_markers and strict_config, or strict mode <strict mode>.

  • #​14456: Fixed pytest.approx not recognizing types with __array_interface__ as numpy-like arrays.

  • #​14474: Fixed a regression where -k and -m expressions containing both backslash characters in identifiers and string literal arguments would incorrectly raise a SyntaxError about escaping.

  • #​14483: Fixed JUnit XML report incorrectly escaping high Unicode codepoints (supplementary plane characters like emoji) in test failure messages. -- by EternalRights

  • #​14492: Fixed Code.getargs() incorrectly including local variable names in the returned argument tuple for functions with *args and/or **kwargs. The method was using co_flags bitmask values (4 and 8) directly as counts instead of converting them to 1 via bool(), and was not accounting for co_kwonlyargcount when var=True.

  • #​3697: Logging capture now works for non-propagating loggers.
    Previously only logs which reached the root logger were captured.
    This includes caplog and the "Captured log calls" test reporting.

  • #​3850: Fixed JUnit XML report: the tests attribute of the <testsuite> element now always matches the number of <testcase> elements in the file. In some cases (test passes but fails during teardown) the tests attribute would report an incorrect number of testcases in the XML file.

  • #​5848: pytest_fixture_post_finalizer is no longer called extra times for the same fixture teardown in some cases.

  • #​719: Fixed @pytest.mark.parametrize <pytest.mark.parametrize ref> not unpacking single-element tuple values when using a string argnames with a trailing comma (e.g., "arg,").

    The trailing comma form now correctly behaves like the tuple form ("arg",), treating argvalues as a list of tuples to unpack.

Improved documentation
  • #​11022: Document safer alternatives and scope guidance for monkeypatching standard library functions.
  • #​11307: Document that @pytest.hookimpl(specname=...) only works for function names starting with pytest_.
  • #​13038: Document that doctests do not support parametrized fixtures, including parametrized autouse fixtures.
  • #​13155: Clarified how the request fixture provides indirect parametrization values via request.param.
  • #​13304: Clarified in the documentation that hook implementations defined in conftest.py files are not available to other plugins during their pytest_addoption() execution, as conftest files are discovered and loaded after builtin and third-party plugins have been initialized. However, initial conftest files themselves can implement pytest_addoption() to add their own command-line options.
  • #​13902: Clarified how subtest progress markers are shown in the documentation.
  • #​14012: The ini options ref section of the API Reference now specified the type and default value of every configuration option.
  • #​14148: Documented a safe pytestconfig.cache access pattern when the
    cacheprovider plugin is disabled.
  • #​14303: The documentation is now built with Sphinx >= 9.
  • #​14465: Updated the hooks how-to page to link the newhooks.py file in pytest-xdist at tag v3.8.0 instead of an unrelated 2017-era commit under the old layout. Pointing at a tag keeps the example in sync with the version users actually install, while remaining stable when the project's main branch moves on.
Miscellaneous internal changes
  • #​14582: Improved the recursion traceback test to exercise all requested traceback styles.

Check out the blog post for a migration
guide and overview of the changes!

Breaking changes
  • Ruff now enables a much larger set of rules by default (413, up from 59). See the blog post for
    more details and the new Default Rules page for a
    full listing of the enabled rules.

  • Ruff can now format Python code blocks in Markdown files and will do this by default. See the
    documentation for more details.

  • Ruff now supports ruff: ignore comments at the ends of lines, like noqa comments, or on the line preceding a diagnostic. For example, these both suppress an unused-import (F401) diagnostic:

    import math  # ruff: ignore[F401]
    
    # ruff: ignore[F401]
    import os
  • Fixes are now shown in check and format --check output:

    ruff format --check .
    unformatted: File would be reformatted
     --> try.md:1:1
      |
    1 | ```python
      - import   math
    2 + import math
    3 | ```
      |
    
    1 file would be reformatted

    This example also shows off the Markdown formatting.

  • format --check now supports the same output formats as the linter, including the github and
    gitlab outputs for rendering annotations in CI:

    ruff format --check --output-format github .
    ::error title=ruff (unformatted),file=try.md,line=2,col=8,endLine=2,endColumn=10::try.md:2:8: unformatted: File would be reformatted

    See the CLI help or documentation for the
    full list of supported formats.

  • The filename, location, end_location, fix.edits[].location, and fix.edits[].end_location
    fields in the JSON output format may now be null rather than defaulting to the empty string and
    row 1, column 1, respectively.
