A GitHub Action that reads Cobertura format code coverage files from your test suite and outputs a text or markdown summary. This summary can be posted as a Pull Request comment or included in Release Notes by other actions to give you an immediate insight into the health of your code without using a third-party site.

Code Coverage Summary is designed for use with any test framework that outputs coverage in Cobertura XML format including Coverlet, gcovr, simplecov and MATLAB. See the FAQ for more details. If it doesn't work with your tooling please open an issue to discuss the problem.

Code Coverage Summary is compatible with StepSecurity Secure Workflows and uses a Docker image that is cryptographically signed using Sigstore. For instructions how to verify the Docker image please see the Wiki.

As a Docker based action Code Coverage Summary requires a Linux runner.

Required

A comma separated list of code coverage files to analyse. Also supports using glob patterns to match multiple files. If there are any spaces in a path or filename this value must be in quotes.

Include a badge reporting the Line Rate coverage in the output using shields.io - true or false (default).

Line Rate	Badge
less than lower threshold (50%)
between thresholds (50% - 74%)
equal or greater than upper threshold (75%)

See thresholds to change these values.

Fail the workflow if the overall Line Rate is below lower threshold - true or false (default). The default lower threshold is 50%, see thresholds.

Output Format - markdown or text (default).

Hide Branch Rate metrics in the output - true or false (default).

Hide Complexity metrics in the output - true or false (default).

Include health indicators in the output - true (default) or false.

See thresholds to change these values.

Output Type - console (default), file or both.

console will output the coverage summary to the GitHub Action log.

file will output the coverage summary to code-coverage-results.txt for text or code-coverage-results.md for markdown format in the workflow's working directory.

both will output the coverage summary to the Action log and a file as above.

Lower and upper threshold percentages for badge and health indicators, lower threshold can also be used to fail the action. Separate the values with a space and enclose them in quotes; default '50 75'.

Version numbers will be assigned according to the Semantic Versioning scheme. This means, given a version number MAJOR.MINOR.PATCH, we will increment the:

1. MAJOR version when we make incompatible API changes
2. MINOR version when we add functionality in a backwards compatible manner
3. PATCH version when we make backwards compatible bug fixes

Please make sure the bug is not already reported by searching existing issues.

If you're unable to find an existing issue addressing the problem please open a new one. Be sure to include a title and clear description, as much relevant information as possible, a workflow sample and any logs demonstrating the problem.

Please open a new issue.

Discuss your idea first, so that your changes have a good chance of being merged in.

Submit your pull request against the master branch.

Pull requests that include documentation and relevant updates to README.md are merged faster, because you won't have to wait for somebody else to complete your contribution.
