In this section, we will explore how to run tests using Firebase Test Lab. Firebase Test Lab provides a cloud-based infrastructure for testing your app across a wide range of devices and configurations. This ensures that your app works well for all users, regardless of their device or operating system.

1. Test Types:

   • Instrumentation Tests: These are tests that run on actual devices and interact with the app's UI.
   • Robo Tests: These are automated tests that explore the app's UI by simulating user interactions.
   • Game Loop Tests: These are tests specifically designed for games, allowing you to test different game scenarios.

2. Device Matrix:

   • A combination of different devices, OS versions, and locales on which the tests will run.

3. Test Results:

   • Detailed reports including logs, screenshots, and videos of the test runs.

Before running tests, ensure that your project is set up in Firebase and that you have access to Firebase Test Lab.

Ensure your app is ready for testing:

• Instrumentation Tests: Write your test cases using a testing framework like Espresso for Android or XCTest for iOS.
• Robo Tests: No additional setup is required.
• Game Loop Tests: Implement the game loop scenarios in your game.

1. Navigate to Test Lab:

   • Go to the Firebase Console.
   • Select your project.
   • Navigate to the "Test Lab" section.

2. Upload Your App:

   • Click on "Run a test".
   • Upload the APK (for Android) or IPA (for iOS) file of your app.

3. Select Test Type:

   • Choose the type of test you want to run (Instrumentation, Robo, or Game Loop).

4. Configure Device Matrix:

   • Select the devices, OS versions, and locales you want to test on.

5. Run the Test:

   • Click on "Start test". Firebase Test Lab will run the tests on the selected devices.

You can also run tests using the Firebase CLI:

1. Install Firebase CLI:

   npm install -g firebase-tools
   

2. Authenticate with Firebase:

   firebase login
   

3. Run the Test:

   firebase test android run --type instrumentation --app <path-to-apk> --test <path-to-test-apk> --device model=Pixel2,version=28
   

After the tests are complete, you can view the results in the Firebase Console:

1. Navigate to Test Lab:

   • Go to the Firebase Console.
   • Select your project.
   • Navigate to the "Test Lab" section.

2. View Test Results:

   • Click on the test run to view detailed results.
   • Analyze logs, screenshots, and videos to identify issues.

1. Upload Your App:

   • Navigate to the Firebase Console.
   • Go to Test Lab and click "Run a test".
   • Upload your APK file.

2. Select Robo Test:

   • Choose "Robo" as the test type.

3. Configure Device Matrix:

   • Select devices like Pixel 3, OS version 29, and locale en_US.

4. Run the Test:

   • Click "Start test".

5. Analyze Results:

   • After the test completes, view the results in the Test Lab section.
   • Check the logs, screenshots, and videos for any issues.

1. Prepare Your Test APK:

   • Ensure you have your app APK and test APK ready.

2. Run the Test:

   firebase test android run --type instrumentation --app app-release.apk --test app-test.apk --device model=Pixel2,version=28
   

3. Analyze Results:

   • After the test completes, view the results in the Firebase Console.

• Incorrect Device Configuration: Ensure that the device model and OS version are correctly specified.
• Test Failures: Check logs and screenshots to understand why a test failed.
• Network Issues: Ensure a stable internet connection when running tests, especially from the CLI.

Running tests in Firebase Test Lab is a powerful way to ensure your app works across a variety of devices and configurations. By following the steps outlined above, you can effectively run and analyze tests, leading to a more robust and reliable app. In the next section, we will delve into analyzing test results in more detail.
