A Github Action to report the code coverage from LCOV files

GitHub Action — Report LCOV

This GitHub Action (written in JavaScript) allows you to leverage GitHub Actions to report the code coverage from LCOV files. This action includes:

• Generating an HTML report as an artifact
• Commenting on a pull request (if the workflow was triggered by this event)
• Failing if a minimum coverage is not met

Usage

Pre-requisites

Create a workflow .yml file in your .github/workflows directory. An example workflow is available below. For more information, reference the GitHub Help Documentation for Creating a workflow file.

Inputs

For more information on these inputs, see the Workflow syntax for GitHub Actions

• coverage-files: The coverage files to scan. For example, coverage/lcov.*.info
• artifact-name: The GitHub artifact name of the generated HTML report. For example, code-coverage-report. Note: When downloading, it will be extracted in an html directory
• minimum-coverage: The minimum coverage to pass the check. Optional. Default: 0 (always passes)
• github-token: Set the ${{ secrets.GITHUB_TOKEN }} token to have the action comment the coverage summary in the pull request. This token is provided by Actions, you do not need to create your own token. Optional. Default: ``
• working-directory: The working directory containing the source files referenced in the LCOV files. Optional. Default: ./

Outputs

None.
