CI Pipeline Configuration Highlights ⚙️

• Structure:
  Each workflow file (.github/workflows/*.yml) has:

  1. A name (e.g., “Unit Testing workflow”).
  2. Triggers (e.g., on: pull_request: branches: [ dev ]).
  3. Jobs that run on ubuntu-latest with steps:
     • Checkout your repo
     • Set up JDK (actions/setup-java@v4)
     • Create local.properties from Secrets
     • Cache Gradle dependencies (actions/cache@v3)
     • Run Gradle tasks (test, bundleRelease, signing, deployment, etc.)

• Actions:

  • actions/checkout@v4
  • actions/setup-java@v4
  • actions/cache@v3
  • r0adkll/sign-android-release@v1
  • r0adkll/[email protected]

• Outputs:

  • Build logs and test results in the GitHub Actions UI.
  • A new signed .aab uploaded to Google Play’s internal track if on qa.

• Containers/Environments:

  • Runs in an ephemeral Ubuntu container provided by GitHub (ubuntu-latest).
  • Java 17 is installed via actions/setup-java.

5. Conclusion

By combining these two GitHub Actions workflows, we have a streamlined CI/CD process:

• Every Pull Request to dev:

  • Runs unit tests to ensure code quality.
  • No deployment; meant for code validation.

• Every Push to qa:

  • Runs the same unit tests.
  • On success, increments the version, builds a release bundle, signs it, and uploads to the Google Play internal testing track for QA.
