pytest 9.0.3 (2026-04-07)

Bug fixes

#12444: Fixed pytest.approx which now correctly takes into account ~collections.abc.Mapping keys order to compare them.
#13634: Blocking a conftest.py file using the -p no: option is now explicitly disallowed.
Previously this resulted in an internal assertion failure during plugin loading.
Pytest now raises a clear UsageError explaining that conftest files are not plugins and cannot be disabled via -p.
#13734: Fixed crash when a test raises an exceptiongroup with __tracebackhide__ = True.
#14195: Fixed an issue where non-string messages passed to unittest.TestCase.subTest() were not printed.
#14343: Fixed use of insecure temporary directory (CVE-2025-71176).

#13388: Clarified documentation for -p vs PYTEST_PLUGINS plugin loading and fixed an incorrect -p example.
#13731: Clarified that capture fixtures (e.g. capsys and capfd) take precedence over the -s / --capture=no command-line options in Accessing captured output from a test function <accessing-captured-output>.
#14088: Clarified that the default pytest_collection hook sets session.items before it calls pytest_collection_finish, not after.
#14255: TOML integer log levels must be quoted: Updating reference documentation.

#12689: The test reports are now published to Codecov from GitHub Actions.
The test statistics is visible on the web interface.
