如何使用Espresso 2.2在Android中测试查看寻呼机滑动手势

Question

我正在使用Espresso 2.2为View pager编写自动化测试,我需要在其中测试滑动功能.

我写了下面的代码:

 @LargeTest
 public class FirstActivityTest {

 @Rule
 public ActivityTestRule<FirstActivity> firstActivityTestRule =
        new ActivityTestRule<>( FirstActivity.class);

@Test
public void testViewPagerSwipeFunctionality() throws InterruptedException{


   onView(withId(R.id.tv_commu)).check(matches(withText(R.string.first_screen_text)));

   onView(withId(R.id.tv_skip)).check(matches(withText(R.string.skip))) ;

   onView(withId(R.id.radio_button_first)).check(matches(isChecked()));
   onView(withId(R.id.view_pager)).perform(swipLeft());

   onView(withId(R.id.radio_button_second))
            .check(matches(isChecked()));
   onView(withId(R.id.tv_comp)).check(matches(withText(R.string.second_screen_text)));

   onView(withId(R.id.tv_skip)).check(matches(withText(R.string.skip))) ;

   onView(withId(R.id.view_pager)).perform(swipeLeft());

   onView(withId(R.id.radio_button_third))
            .check(matches(isChecked()));
   onView(withId(R.id.tv_skip)).check(matches(withText(R.string.skip))) ;
    onView(withId(R.id.tv_person)).check(matches(withText(R.string.third_screen_text)));}}

但是swipeLeft()方法没有得到解决.请告诉我我在哪里做错了？我们将非常感谢您的帮助.

你必须导入swipeLeft(),如:

import static android.support.test.espresso.action.ViewActions.swipeLeft;

附注:示例代码具有swipLeft()而不是swipeLeft().
