安卓UI测试（基于android studio环境 espresso框架）

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

public class AndroidTest {
    private static final String a = "peter";
    @Rule
    public ActivityTestRule<MainActivity> mActivityRule
            = new ActivityTestRule<MainActivity>(MainActivity.class);

    @Test
    public void sayHello() {

       onView(withId(R.id.editText)). perform(typeText(a), closeSoftKeyboard());

        onView(withText("Say hello!")).perform(click());

        String expectedText = "Hello, " + a + "!";

        onView(withId(R.id.textView)).check(matches(withText(expectedText)));
    }
}

 

测试过程及结果
