This test project comes with all the required Android Testing Support Library dependencies
in the Gradle file. Tests are under the app/src/androidTest folder.
Note that before running your tests, you might want to turn off animations on your test device. It's a known issue that leaving system animations turned on in a test device (window animation scale, transition animation scale, animator duration scale) might cause unexpected results, or may lead tests to fail.
To create a new run configuration:
- Click on Run -> Edit Configurations...
- Click on the plus sign and then on "Android Tests"
- Give a name to the configuration, e.g.
TestAppTests - Choose the
MapboxGLAndroidSDKTestAppmodule - Choose
android.support.test.runner.AndroidJUnitRunneras the instrumentation runner - Click OK to save the new configuration
You can now run this configuration from the main toolbar dropdown menu.
Tests are under the app/src/androidTest folder.
- Sign In with your Google account.
- Or Add Account if you want to sign in with a different account.
-
Select the test configuration you want to run and click Play button.
-
Click on Cloud Testing tab. You need to create a project in Firebase and define a Matrix configuration previously (see Firebase Test Lab for Android guide). Select your template (e.g. Nexus 5 (3)).
-
Select your Cloud project (e.g. android-gl-native (android-gl-native)).
- Click on OK button to run the tests.
- When tests finish the results will appear within AS.
On a terminal, within mapbox-gl-native/android/java,
run the tests (cC stands for connectedCheck):
$ ./gradlew -Pmapbox.abis=all cC -p MapboxGLAndroidSDKTestApp
Then:
- Go to your AWS Console and choose Device Farm.
- Create a new project, e.g.
MapboxGLAndroidSDKTestApp - On step 1, upload the APK in
mapbox-gl-native/android/java/MapboxGLAndroidSDKTestApp/build/outputs/apk/MapboxGLAndroidSDKTestApp-debug-unaligned.apk - On step 2, choose Instrumentation, test filter is
com.mapbox.mapboxgl.testapp.MainActivityTestand upload the APK inmapbox-gl-native/android/java/MapboxGLAndroidSDKTestApp/build/outputs/apk/MapboxGLAndroidSDKTestApp-debug-androidTest-unaligned.apk - On step 3, choose a device pool. E.g. Top Devices
- On step 4, customize your device state (if needed)
- Finally, confirm the configuration and run the tests.
On Step 2, you can also separate by commas different classes: com.mapbox.mapboxgl.testapp.MainActivityTest,com.mapbox.mapboxgl.testapp.MainActivityScreenTest
If you have no tests for your app, or want to test some random user behavior, you can just choose "Built-in: Fuzz" in step 2.
These tests run on a local JVM on your development machine and they are extremely fast to run
(as compared to Espresso). These tests are located under src/test/java. To run them you switch
to the Unit Tests build variant, then right click the corresponding test class or method
and select "Run ...".
You can also have a run configuration:
- Click on Run -> Edit Configurations...
- Click on "Junit Tests"
- Give a name to the configuration, e.g.
JUnit tests - As "Test Kind", choose "All in directory"
- As folder, choose the following folder:
mapbox-gl-native/android/java/MapboxGLAndroidSDKTestApp/src/test/java - Click OK to save the new configuration
You can also run the tests from the command line with:
$ ./gradlew -Pmapbox.abis=none test -p MapboxGLAndroidSDKTestApp
Similar to the "Built-in: Fuzz" test mentioned above, Android provides Monkey, "a program that runs on your emulator or device and generates pseudo-random streams of user events such as clicks, touches, or gestures, as well as a number of system-level events."
To exercise Monkey on the test app, install the package on the device (e.g. via Android Studio) and then:
$ adb shell monkey -p com.mapbox.mapboxgl.testapp -v 500
