The Android Test Orchestrator allows you to run each of your app's tests in isolation, enabling greater reliability. See https://developer.android.com/training/testing/junit-runner#using-android-test-orchestrator for more background.
This sample is a subset of the AndroidJUnitRunner sample, but it illustrates how to enable Jacoco test coverage report with the Android Test Orchestrator in the app/build.gradle file.
This project uses the Gradle build system. You don't need an IDE to build and execute it but Android Studio is recommended.
- Download the project code, preferably using
git clone. - Open the Android SDK Manager (Tools Menu | Android).
- In Android Studio, select File | Open... and point to the top-level
./build.gradlefile. - Check out the relevant code:
- The application under test is located in
src/main/java - Tests are in
src/androidTest/java
- The application under test is located in
- Connect a device or start an emulator:
- Turn animations off. (On your device, under Settings->Developer options disable the following 3 settings: "Window animation scale", "Transition animation scale" and "Animator duration scale")
- Run the newly created configuration.
The application will be started on the device/emulator and a series of actions will be performed automatically.
If you are using Android Studio, the Run window will show the test results.
The test coverage report will be generated in app/build/reports/coverage/androidTest/debug/index.html.
