用户登录界面测试，在新包里新建一个测试类如图

 

测试代码如下

1 public class AndroidTest { 2     private static final String a = "peter"; 3     @Rule 4     public ActivityTestRule
     
       mActivityRule 5             = new ActivityTestRule
      
       (MainActivity.class); 6  7     @Test 8     public void sayHello() { 9 10        onView(withId(R.id.editText)). perform(typeText(a), closeSoftKeyboard());11 12         onView(withText("Say hello!")).perform(click());13 14         String expectedText = "Hello, " + a + "!";15 16         onView(withId(R.id.textView)).check(matches(withText(expectedText)));17     }18 }
