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

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.myTestId));
}

The selector works fine to check if the view is displayed, but gives error on checking if the view not displayed. I am using this as follows:

 onMyTestUi().check(matches(not(isDisplayed())));

But I get the following error:

com.google.android.apps.common.testing.ui.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: is If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one of the following AdapterViews:android.widget.ListView{...}

This is strange. I am checking the absence of the UI and its expected that this view won't be found. Then why Espresso is throwing error? Please suggest what might be going wrong here.

You can try this option if you check the view visibility "withEffectiveVisibility"

    onView(withId(R.id.YOURVIEW)).check(matches(ViewMatchers.withEffectiveVisibility(ViewMatchers.Visibility.GONE)))

Need to use doesNotExist() instead. Found here.

If the view is there in the view hierarchy but in an invisible state (visibility is set to 'INVISIBLE'), use not(isDisplayed). However, if the view is not there at all in the view hierarchy (e.g. visibility set to 'GONE'), doesNotExist() is used.

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());

Also work with yours method, but something like this:

onView(withId(R.id.next)).check(matches(not(isDisplayed())));
