We already have a test that verifies that we have a button that hekps us display a new joke each it is clicked. But we also need to make sure that when the app is just launched a joke is displayed to our user automatically. We need to add a test for that.

declareMock<Repository>{

whenever(getJoke()){
	.thenReturn(Single.just(joke))
	.onView(withId(R.id.textJoke))
	.check(matches(withText(joke.joke)))
}

}
