集成测试

集成测试主要针对不直接用用户交互的组件，比如service和contentprovider。

测试 service

1. RunWith(AndroidJUnit4.class)并且指定AndroidJUnitRunner
2. 创建ServiceTestRule通过@Rule注释

3. 编写测试方法

   @Test
   public void testWithBoundService() throws TimeoutException {
       // Create the service Intent.
       Intent serviceIntent =
               new Intent(InstrumentationRegistry.getTargetContext(),
                   LocalService.class);
   
       // Data can be passed to the service via the Intent.
       serviceIntent.putExtra(LocalService.SEED_KEY, 42L);
   
       // Bind the service and grab a reference to the binder.
       IBinder binder = mServiceRule.bindService(serviceIntent);
   
       // Get the reference to the service, or you can call
       // public methods on the binder directly.
       LocalService service =
               ((LocalService.LocalBinder) binder).getService();
   
       // Verify that the service is working correctly.
       assertThat(service.getRandomInt(), is(any(Integer.class)));
   }
   

   测试 contentprovider
