matches(not(isDisplayed())) fails with NoMatchingViewException

Question

I am trying to test the absence of the UI view. The view selector is as follows:

public static ViewInteraction onMyTestUi() {
    return onView(withId(R.id.m         


        

Answer 1

If you want to check if View is either not visible or does not exist.

public static ViewAssertion isNotDisplayed() {
    return new ViewAssertion() {
        @Override
        public void check(View view, NoMatchingViewException noView) {
            if (view != null && isDisplayed().matches(view)) {
                throw new AssertionError("View is present in the hierarchy and Displayed: "
                        + HumanReadables.describe(view));
            }
        }
    };
}

Usage:

onView(withId(R.id.someView)).check(isNotDisplayed());
