I was playing with espresso around and I noticed that one of my buttons is failing to click. I tried to move it around on the screen and everything to make it be automatically clicked, but failed. Then I noticed that it had a rotation=180. And by removing it The problem seemed to be resolved, but it is needed.

Here is my code for the test:

@Test

public void orderUp() throws Exception {

    onView(ViewMatchers.withId(R.id.move_up)).perform(ViewActions.click());

    onView(withText("Up")).inRoot(withDecorView(not(is(menuActivityTestRule.getActivity().getWindow().getDecorView())))).check(matches(isDisplayed()));

}

So, how to make the test case work for a rotated button?

Edit: 'Error Log indicating that The Toast wasn't found I Think'

ViewActions.click finds coordinates of a view on the screen, and then performs/simulates a tap on the coordinates. I'm not exactly sure but it seems that setRotation may have affected coordinates calculation. An alternative solution would be creating a custom click action:

public static ViewAction forceClick() {

    return new ViewAction() {

        @Override public Matcher<View> getConstraints() {

            return allOf(isClickable(), isEnabled());

        }



        @Override public String getDescription() {

            return "force click";

        }



        @Override public void perform(UiController uiController, View view) {

            view.performClick();

            uiController.loopMainThreadUntilIdle();

        }

    };

}

This action performs click on the view by invoking performClick() without finding its coordinates. But make sure the view has the click listener attached in the app

onView(withId(R.id.move_up)).perform(forceClick());
