## AI interpretation — verify before relying

A pytest plugin that measures code coverage during test runs, automatically combining coverage data and supporting distributed testing with pytest-xdist.

Verdict: Mature, well-maintained pytest plugin in the top 1000 PyPI packages with zero known vulnerabilities. Low install friction and permissive MIT licensing make it a straightforward choice for adding coverage measurement to test suites. Active development and broad Python version support (3.9–3.14) ensure compatibility.
