Release Notes

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

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.
