Firebase Test Lab is a cloud-based app-testing infrastructure that allows you to test your Android and iOS apps on a wide range of devices and configurations. It helps you ensure the quality and performance of your app by running automated tests on physical and virtual devices hosted by Google.
Key Concepts
- Device Matrix: A combination of device models, OS versions, screen orientations, and locales on which your app can be tested.
- Test Types: Firebase Test Lab supports various types of tests, including instrumentation tests, Robo tests, and game loop tests.
- Test Results: Detailed reports including logs, screenshots, and videos of the test runs.
- Integration: Firebase Test Lab can be integrated with CI/CD pipelines to automate testing.
Setting Up Firebase Test Lab
Prerequisites
- A Firebase project.
- An Android or iOS app connected to your Firebase project.
- Basic knowledge of writing tests for your app.
Steps to Set Up Firebase Test Lab
-
Navigate to Firebase Console:
- Go to the Firebase Console.
- Select your project.
-
Access Test Lab:
- In the left-hand menu, click on "Test Lab".
-
Upload Your App:
- Click on "Upload your app".
- Select the APK (for Android) or IPA (for iOS) file of your app.
-
Choose Test Type:
- Select the type of test you want to run (Instrumentation, Robo, or Game Loop).
-
Configure Device Matrix:
- Choose the devices, OS versions, screen orientations, and locales you want to test on.
-
Run the Test:
- Click on "Start Test" to begin the testing process.
Types of Tests
Instrumentation Tests
Instrumentation tests are written using testing frameworks like Espresso (for Android) or XCTest (for iOS). These tests interact with the app's UI and verify that it behaves as expected.
Example: Android Instrumentation Test
@RunWith(AndroidJUnit4.class)
public class ExampleInstrumentedTest {
@Test
public void useAppContext() {
// Context of the app under test.
Context appContext = InstrumentationRegistry.getInstrumentation().getTargetContext();
assertEquals("com.example.myapp", appContext.getPackageName());
}
}Robo Tests
Robo tests automatically simulate user interactions with your app. They explore the app's UI and generate a report of any crashes or issues found.
Game Loop Tests
Game Loop tests are designed for testing games. They run predefined loops in your game to simulate gameplay and check for performance issues or crashes.
Viewing Test Results
After the tests are completed, Firebase Test Lab provides detailed reports that include:
- Logs: Console logs and crash logs.
- Screenshots: Screenshots taken during the test run.
- Videos: Videos of the test run.
- Performance Metrics: CPU, memory, and network usage.
Accessing Test Results
-
Navigate to Test Lab in Firebase Console:
- Go to the "Test Lab" section in your Firebase project.
-
View Test Results:
- Click on the test run you want to review.
- Explore the logs, screenshots, and videos provided.
Practical Exercise
Exercise: Running a Robo Test
-
Upload Your App:
- Go to the Firebase Console and upload your APK or IPA file.
-
Select Robo Test:
- Choose the Robo test option.
-
Configure Device Matrix:
- Select at least two different devices and OS versions.
-
Run the Test:
- Start the test and wait for it to complete.
-
Review Results:
- Check the logs, screenshots, and videos for any issues.
Solution
-
Upload Your App:
- Navigate to the Firebase Console, select your project, and upload your app file.
-
Select Robo Test:
- Choose the Robo test option from the test types.
-
Configure Device Matrix:
- Select devices like Pixel 3 (Android 9) and Nexus 5X (Android 8).
-
Run the Test:
- Click "Start Test" and wait for the test to complete.
-
Review Results:
- Go to the Test Lab section, select the test run, and review the logs, screenshots, and videos.
