使用 Gradle 运行特定的 Android 检测测试

Question

I need to execute certain Android test case (Class or method) with gradle from console. It is located at src/androidTest/java/com/example/CertainTest.java .

Android Studio makes this available via complicated adb shell am instrument .

Is it possible to invoke certain Android Test only via Gradle?

I have read about How to run only one test class on gradle , Test from the Command Line but is it quite complicated way of doing that.

This is how Android Studio launches specific Test Class:

Launching Tests
$ adb push /.../app/build/outputs/apk/app-debug.apk /data/local/tmp/com.example.andrii.espressotutorial
$ adb shell pm install -r "/data/local/tmp/com.example.andrii.espressotutorial"
    pkg: /data/local/tmp/com.example.andrii.espressotutorial
Success
$ adb push /.../app/build/outputs/apk/app-debug-androidTest.apk /data/local/tmp/com.example.andrii.espressotutorial.test
$ adb shell pm install -r "/data/local/tmp/com.example.andrii.espressotutorial.test"
    pkg: /data/local/tmp/com.example.andrii.espressotutorial.test
Success
Running tests
$ adb shell am instrument -w -r   -e debug false -e class com.example.andrii.espressotutorial.ExampleInstrumentedTest2 com.example.andrii.espressotutorial.test/android.support.test.runner.AndroidJUnitRunner

You can write a gradle task like this:

In the main gradle file

apply from: "$project.rootDir/tools/script-integration-tests.gradle"

Then create a directory tools and a file script-integration-tests.gradle in the project directory. Then fill it with the test class name like this.

apply plugin: 'com.android.application'

task integrationTest(type: Exec) {
    def adb = android.getAdbExe().toString()
    commandLine "$adb", 'shell', 'am', 'instrument', '-w', '-r', '-e',
            'debug', 'false', '-e', 'class', 'de.app.id.PullRequestTests',
            'de.app.id.app_test.debug.test/android.support.test.runner.AndroidJUnitRunner'
}
