code-coverage-summary-action

A GitHub Action to summarize JaCoCo code coverage in Gradle builds

It collects JaCoCo results from each subproject and reports on code coverage for each subproject. The report is a simple table written to the GITHUB_STEP_SUMMARY.

To Use

Here is an example workflow as an example of using this GitHub Action in a job's steps.

jobs:
  build:
    steps:
    - name: Checkout the repo
      uses: actions/checkout@v4

    - name: Set up JDK 17
      uses: actions/setup-java@v4
      with:
        java-version: '17'
        distribution: 'temurin'
    - name: Setup Gradle
      uses: gradle/actions/setup-gradle@v3
    - name: Build with Gradle Wrapper
      run: ./gradlew testCodeCoverageReport

    - name: Summarize tests results
      uses: jeantessier/code-coverage-summary-action@v1

It will produce a summary table like the following.
