Test text submit on SearchView when using Espresso

问题

How can I submit some text to SearchView in androidTest?

onView(withId(R.id.search_src_text)).perform(typeText("text")) doesn't work for me - app crashes at this line

@Test
fun testSearchViewTextSubmit() {
    ActivityScenario.launch(MainActivity::class.java)

    onView(withId(R.id.search_action)).perform(click()) // ok 

    onView(withId(R.id.search_src_text)).perform(typeText("text")) // failed
}

androidx.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: com.example.test:id/search_src_text

@LorenzoCamaione answer was success when I tried with my application.

        onView(withId(android.support.design.R.id.search_src_text)).perform(typeText("example"), pressKey(
        KeyEvent.KEYCODE_ENTER));
