Espresso Instrumented 测试，层次结构中找不到与 RecycleView 匹配的视图

Question

I have 3 items in Bottom Navigation:

1. Movie
2. Tv Show
3. Favorite (TabLayout with 2 items, default tab("Movie") & Second tab("Tv Show"))

On the default tab (Favorite Movie) was successful.

onView(withId(R.id.nav_favorite)).perform(click())
onView(allOf(withId(R.id.rv_favorite_film), isDisplayed())).check(matches(isDisplayed())) //SUCCESS

I have a problem in Favorite Item -> Second tab Tv Show when testing:

onView(withId(R.id.nav_favorite)).perform(click())
onView(allOf(withText("Tv Show"), isDescendantOfA(withId(R.id.tabs)))).perform(click())
onView(allOf(withId(R.id.rv_favorite_tvshow), isDisplayed())).check(matches(isDisplayed())) //ERROR

How to fix it?. Thanks

Answer 1

I think you're performing a click action on a TextView which is not the View that has the onClickListener attached to it.

Within TabLayout you have a hierarchy of TabViews with TextViews nested within them. The thing that has an onClickListener is not the TextView (matching allOf(withText("Tv Show"), isDescendantOfA(withId(R.id.tabs))) ) but the TabView .

So you should perform(click()) on a TabView that has a child withText("Tv Show") .

I don't remember the exact syntax of Espresso, but if you tried using my Cortado library () it should be:

Cortado.onView().isAssignableFrom(TabView::class.java).and().hasDescendant(withText("Tv Show")).perform().click()
