1.添加依赖 

androidTestImplementation 'androidx.test.uiautomator:uiautomator:2.2.0'

2.在下图箭头所指创建 

3.打开你要测试的软件

public class Module1 { 

    private UiDevice device;


   @Before   // 首先打开软件

   public void Befroe(){

       Instrumentation instrumentation=getInstrumentation();

       device=UiDevice.getInstance(instrumentation);

       Context context=instrumentation.getTargetContext().getApplicationContext();

 Intent intent=context.getPackageManager().getLaunchIntentForPackage("com.example.moudle");
//你的运行名

       intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);

       context.startActivity(intent);

   }

4.下面就可以开始写你要测试的功能 

   @Test
    public void start() throws InterruptedException, UiObjectNotFoundException {
       

   // TODO 测试 button按钮 是否能够使用

     UiObject Loging= device.findObject(newUiSelector().resourceId
("com.example.moudle:id/Loging"));  //发现button按钮      
       Loging.click(); // 点击按钮
       Log.e("第一次点击按钮","弹出Toast" ); //如果成功则打印出来
       sleep(3000); //休眠3秒 继续下一步测试


   // TODO 测试 Textview 是否能够使用

      UiObject usernmae=device.findObject(new UiSelector().resourceId
("com.example.moudle:id/usernmae"));

      usernmae.setText("123456");
      Log.e("输入用户名","输入成功" );
      sleep(3000);


   // TODO  垂直滚动 scrowview

    UiScrollable scrowView=new UiScrollable(new UiSelector().scrollable(true));
    scrowView.scrollForward(); //向下滚动
    scrowView.scrollBackward(); //向上滚动


   // TODO 列表横向滑动 gridview

    UiObject gridview= device.findObject(new UiSelector().resourceId("com.example.moudle:id/gridview"));

    g1.swipeLeft(1000);
    g1.swipeRight(1000);



  // TODO 最后结束测试
  @After
       public void After() throws InterruptedException {

          sleep(100000); 

   }


}
