Spoon和Espresso测试

Question

所以，我有一个测试，它贯穿了我的整个应用程序。现在，我想把所有的东西都拍下来。因为它有两个活动和大量的片段，我不能让它工作，因为它只需要每个活动的第一个片段。

我如何才能实现拍摄每个片段的照片？

   @RunWith(AndroidJUnit4.class)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class HearthBeatUITest {

    private final int MILISECONDS_TIMEOUT = 700;

    @Rule
    public ActivityTestRule<IntroActivity> mActivityRule = new ActivityTestRule<>(IntroActivity.class);
    @Rule
    public ActivityTestRule<LoginActivity> mLoginActivityRule = new ActivityTestRule<>(LoginActivity.class);

    @Test
    /**
     * Testing all the screens on the application if they are actually there
     */
    public void startTest() {
        Session.clear();
        Spoon.screenshot(mActivityRule.getActivity(), "initial_state");
        threadSleep(MILISECONDS_TIMEOUT);
        onView(withId(R.id.button_register)).check(matches(isDisplayed())).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        Spoon.screenshot(mLoginActivityRule.getActivity(), "register_intro");
        onView(withId(R.id.register_with_email)).check(matches(isDisplayed())).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        Spoon.screenshot(mLoginActivityRule.getActivity(), "register_detailed");
        onView(withId(R.id.image_left_button)).check(matches(isDisplayed())).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        Spoon.screenshot(mLoginActivityRule.getActivity(), "register_intro");
        onView(withId(R.id.image_left_button)).check(matches(isDisplayed())).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        Spoon.screenshot(mActivityRule.getActivity(), "initial_state");
        onView(withId(R.id.button_signin)).check(matches(isDisplayed())).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        Spoon.screenshot(mLoginActivityRule.getActivity(), "login_intro");
        onView(withId(R.id.sign_in_emal)).check(matches(isDisplayed())).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        Spoon.screenshot(mLoginActivityRule.getActivity(), "login_detailed");
    }

}

Answer 1

首先，你只需要一条规则：

@RunWith(AndroidJUnit4.class)
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class HearthBeatUITest {

    private final int MILISECONDS_TIMEOUT = 300;
    @Rule
    public IntentsTestRule<IntroActivity> mActivityRule = new IntentsTestRule<>(IntroActivity.class);
    private Activity currentActivity;
}

现在，当您需要创建截图的上下文时，您可以调用此方法：

   private Activity getActivityInstance() {
        getInstrumentation().runOnMainSync(new Runnable() {
            public void run() {
                Collection resumedActivities = ActivityLifecycleMonitorRegistry.getInstance().getActivitiesInStage(RESUMED);
                if (resumedActivities.iterator().hasNext()) {
                    currentActivity = (Activity) resumedActivities.iterator().next();
                }
            }
        });

        return currentActivity;
    }

它会让你看到当前的活动，你还可以截图。仅供参考，你不能截取对话的截图。
