testBuildType

abstract var testBuildType: String

Specifies the build type that the plugin should use to test the module.

By default, the Android plugin uses the "debug" build type. This means that when you deploy your instrumented tests using gradlew connectedAndroidTest, it uses the code and resources from the module's "debug" build type to create the test APK. The plugin then deploys the "debug" version of both the module's APK and the test APK to a connected device, and runs your tests.

To change the test build type to something other than "debug", specify it as follows:

android {
    // Changes the test build type for instrumented tests to "stage".
    testBuildType "stage"
}

If your module configures product flavors the plugin creates a test APK and deploys tests for each build variant that uses the test build type. For example, consider if your module configures "debug" and "release" build types, and "free" and "paid" product flavors. By default, when you run your instrumented tests using gradlew connectedAndroidTest, the plugin performs executes the following tasks:

• connectedFreeDebugAndroidTest: builds and deploys a freeDebug test APK and module APK, and runs instrumented tests for that variant.
• connectedPaidDebugAndroidTest: builds and deploys a paidDebug test APK and module APK, and runs instrumented tests for that variant.

Note: You can execute connected<BuildVariant>AndroidTest tasks only for build variants that use the test build type. So, by default, running connectedStageAndroidTest results in the following build error:

Task 'connectedStageAndroidTest' not found in root project

You can resolve this issue by changing the test build type to "stage".
