In this example, the pipeline includes four stages: build, test, and deploy.
The before_script section installs the necessary dependencies for both Android and iOS development.
The build_android and test_android stages run the gradlew commands to build and test the Android application, and the build_ios and test_ios stages run the xcodebuild commands to build and test the iOS application.
The deploy_ios stage uses the fastlane tool to deploy the iOS application to Testflight, and the deploy_android stage uses the ./gradlew firebase_deploy command to deploy the Android application to Firebase.
Push your code to the GitLab repository and trigger the pipeline.
The pipeline will run automatically on each push to the repository, and the results will be available in the GitLab UI.
This is just one example of how to set up a GitLab CI/CD pipeline to build, test, and deploy an Android and iOS application using Docker and Firebase/Testflight.
The exact steps and configurations may vary depending on your specific requirements and the tools and technologies you use.
However, the goal is to automate the process of building, testing, and deploying your applications, so that you can ensure the quality and reliability of your code with each change.
