Release Notes

pytest-dev/pytest-cov (pytest-cov)

v7.1.0

Compare Source

• Fixed total coverage computation to always be consistent, regardless of reporting settings.
  Previously some reports could produce different total counts, and consequently can make --cov-fail-under behave different depending on
  reporting options.
  See #&#8203;641 <https://github.com/pytest-dev/pytest-cov/issues/641>_.

• Improve handling of ResourceWarning from sqlite3.

  The plugin adds warning filter for sqlite3 ResourceWarning unclosed database (since 6.2.0).
  It checks if there is already existing plugin for this message by comparing filter regular expression.
  When filter is specified on command line the message is escaped and does not match an expected message.
  A check for an escaped regular expression is added to handle this case.

  With this fix one can suppress ResourceWarning from sqlite3 from command line::

  pytest -W "ignore:unclosed database in <sqlite3.Connection object at:ResourceWarning" ...

• Various improvements to documentation.
  Contributed by Art Pelling in #&#8203;718 <https://github.com/pytest-dev/pytest-cov/pull/718>_ and
  "vivodi" in #&#8203;738 <https://github.com/pytest-dev/pytest-cov/pull/738>.
  Also closed #&#8203;736 <https://github.com/pytest-dev/pytest-cov/issues/736>.

• Fixed some assertions in tests.
  Contributed by in Markéta Machová in #&#8203;722 <https://github.com/pytest-dev/pytest-cov/pull/722>_.

• Removed unnecessary coverage configuration copying (meant as a backup because reporting commands had configuration side-effects before coverage 5.0).

v7.0.0

Compare Source

• Dropped support for subprocesses measurement.

  It was a feature added long time ago when coverage lacked a nice way to measure subprocesses created in tests.
  It relied on a .pth file, there was no way to opt-out and it created bad interations
  with coverage's new patch system <https://coverage.readthedocs.io/en/latest/config.html#run-patch>_ added
  in 7.10 <https://coverage.readthedocs.io/en/7.10.6/changes.html#version-7-10-0-2025-07-24>_.

  To migrate to this release you might need to enable the suprocess patch, example for .coveragerc:

  .. code-block:: ini

  [run]
  patch = subprocess

  This release also requires at least coverage 7.10.6.

• Switched packaging to have metadata completely in pyproject.toml and use hatchling <https://pypi.org/project/hatchling/>_ for
  building.
  Contributed by Ofek Lev in #&#8203;551 <https://github.com/pytest-dev/pytest-cov/pull/551>_
  with some extras in #&#8203;716 <https://github.com/pytest-dev/pytest-cov/pull/716>_.

• Removed some not really necessary testing deps like six.

v6.3.0

Compare Source

• Added support for markdown reports.
  Contributed by Marcos Boger in #&#8203;712 <https://github.com/pytest-dev/pytest-cov/pull/712>_
  and #&#8203;714 <https://github.com/pytest-dev/pytest-cov/pull/714>_.
• Fixed some formatting issues in docs.
  Anonymous contribution in #&#8203;706 <https://github.com/pytest-dev/pytest-cov/pull/706>_.

v6.2.1

Compare Source

• Added a version requirement for pytest's pluggy dependency (1.2.0, released 2023-06-21) that has the required new-style hookwrapper API.

• Removed deprecated license classifier (packaging).

• Disabled coverage warnings in two more situations where they have no value:

  • "module-not-measured" in workers
  • "already-imported" in subprocesses

v6.2.0

Compare Source

• The plugin now adds 3 rules in the filter warnings configuration to prevent common coverage warnings being raised as obscure errors::

  default:unclosed database in <sqlite3.Connection object at:ResourceWarning
  once::PytestCovWarning
  once::CoverageWarning

  This fixes most of the bad interactions that are occurring on pytest 8.4 with filterwarnings=error.

  The plugin will check if there already matching rules for the 3 categories
  (ResourceWarning, PytestCovWarning, CoverageWarning) and message (unclosed database in <sqlite3.Connection object at) before adding the filters.

  This means you can have this in your pytest configuration for complete oblivion (not recommended, if that is not clear)::

  filterwarnings = [
  "error",
  "ignore:unclosed database in <sqlite3.Connection object at:ResourceWarning",
  "ignore::PytestCovWarning",
  "ignore::CoverageWarning",
  ]

v6.1.1

Compare Source

• Fixed breakage that occurs when --cov-context and the no_cover marker are used together.

v6.1.0

Compare Source

• Change terminal output to use full width lines for the coverage header.
  Contributed by Tsvika Shapira in #&#8203;678 <https://github.com/pytest-dev/pytest-cov/pull/678>_.
• Removed unnecessary CovFailUnderWarning. Fixes #&#8203;675 <https://github.com/pytest-dev/pytest-cov/issues/675>_.
• Fixed the term report not using the precision specified via --cov-precision.

v6.0.0

Compare Source

• Updated various documentation inaccuracies, especially on subprocess handling.
• Changed fail under checks to use the precision set in the coverage configuration.
  Now it will perform the check just like coverage report would.
• Added a --cov-precision cli option that can override the value set in your coverage configuration.
• Dropped support for now EOL Python 3.8.
