Android Espresso check selected spinner text

Really simple solution that worked out for me .....without using matcher for CustomSpinner

onView(withId(R.id.custom_spinner)).perform(click());
onData(anything()).atPosition(1).perform(click());
onView(withId(R.id.custom_spinner)).check(matches(withSpinnerText(containsString("yourstring"))));

For custom adapter i had yo create a custom matcher:

 onView(withId(R.id.spinner)).perform(click());
 onData(allOf(is(instanceOf(YourCustomClass.class)), withMyValue("Open"))).perform(click());


public static <T> Matcher<T> withMyValue(final String name) {
    return new BaseMatcher<T>() {
        @Override
        public boolean matches(Object item) {
            return item.toString().equals(name);
        }

        @Override
        public void describeTo(Description description) {

        }
    };
}

Then you must override toString() method on your custom class.

Replace withText() with withSpinnerText()

onView(withId(spinnerId)).perform(click());
onData(allOf(is(instanceOf(String.class)), is(selectionText))).perform(click());
onView(withId(spinnerId)).check(matches(withSpinnerText(containsString(selectionText))));
