[dependabot]

Updates the requirements on pytest-cov to permit the latest version.

Changelog

Sourced from pytest-cov's changelog.

6.3.0 (2025-09-06)

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

6.2.1 (2025-06-12)

• 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

6.2.0 (2025-06-11)

• 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", ]

6.1.1 (2025-04-05)

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

6.1.0 (2025-04-01)
