如何在Android Studio使用Espresso框架自动化测试

1，Open your app's build.gradle file. This is usually not the top-level build.gradle file but app/build.gradle. Add the following lines inside dependencies:

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'

androidTestCompile 'com.android.support.test:runner:0.5'

2，Set the instrumentation runner, add to the same build.gradle file the following line in android.defaultConfig:

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

3，Add the first test in src/androidTest/java/

@RunWith(AndroidJUnit4.class)

@LargeTest

public class HelloWorldEspressoTest {

      @Rule

      public ActivityTestRule<MainActivity>mainActivity = new ActivityTestRule(MainActivity.class);

      @Test

      public void TestElement(){

              onView()... 

     }

}

4，Create a test configuration, Run menu - Edit Configurations - Add a new Android Tests configuration - Choose a module - Add a specific instrumentation runner (android.support.test.runner.AndroidJUnitRunner)
