This repo provides a minimal Python package and GitHub Action for reporting the outcomes of Python coverage as a check and annotations on a GitHub pull request.

Most users—especially those with public repositories—will want to use services like Codecov, Coveralls. These services provide free options for public repos with many more features, and paid options for private repos with professional support. You should consider paying for these if your organization can afford it! If not, then coverage-gh fills the niche as "poor man's" option for private repos.

The action assumes your workflow invokes coverage (e.g. using pytest-cov) to generate a date file, named .coverage by default. This is the only file needed by the action, i.e., you do not need to give arguments like pytest … --cov-report=xml unless otherwise needed.
