java - 我重写的方法无法正常工作，代码进入方法，但不执行

Question

我为应用程序编写自动测试。在应用程序启动时，它有一个入门(ViewPager)，其中有一些页面和最后一页上的按钮。我需要滑动这些页面并按下按钮。这是我的入职类(class)

public class Onboarding {

ViewInteraction onboardingScreen = onView(
        allOf(withId(R.id.vp_onboarder_pager),
                childAtPosition(
                        allOf(withId(R.id.cl_onboarder),
                                childAtPosition(
                                        withId(android.R.id.content),
                                        0)),
                        0),
                isDisplayed()));

ViewInteraction skipButton = onView(allOf(withId(R.id.btn_finish)));

ViewAction skipOnboardingScreen = new ViewAction() {
    @Override
    public Matcher<View> getConstraints() {
        return any(View.class);
    }

    @Override
    public String getDescription() {
        return null;
    }

    @Override
    public void perform(UiController uiController, View view) {
        ViewPager onboardingPager = (ViewPager) view;
        OnboarderAdapter adapter = (OnboarderAdapter) onboardingPager.getAdapter();
        int currentPage = 0;
        int screenCount = adapter.getCount();
        while (screenCount > 0){
            onboardingPager.setCurrentItem(currentPage);
            screenCount--;
            currentPage++;
        }
        skipButton.perform(click());
    }
};

public void skipOnboarding() {
       onboardingScreen.perform(skipOnboardingScreen); 
}

我这样称呼我的测试:

@Test
public void onboardingPass() {

    try {
        Thread.sleep(5000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

    Onboarding onboarding = new Onboarding();
    onboarding.skipOnboarding();

}

测试执行时，onboardingPager.setCurrentItem(currentPage)必须切换当前页面，但事实并非如此。当我在调试器中看到它时，测试执行这一行，但页面没有切换。为什么可以呢？谢谢。

... I need to swipe these pages ...

要在仪器测试中滑动，请将其与您的 View 结合使用；

onboardingScreen.perform(swipeRight());

swipeRight() 来自AndroidX Test包 androidx.test.espresso.action.ViewActions.swipeRight

根据您的要求设置滑动，看看是否有帮助。
