Answer 1

For the ones looking to check the visibility status for a view; here are some utility functions I use.

fun ViewInteraction.isGone() = getViewAssertion(ViewMatchers.Visibility.GONE)

fun ViewInteraction.isVisible() = getViewAssertion(ViewMatchers.Visibility.VISIBLE)

fun ViewInteraction.isInvisible() = getViewAssertion(ViewMatchers.Visibility.INVISIBLE)

private fun getViewAssertion(visibility: ViewMatchers.Visibility): ViewAssertion? {
    return ViewAssertions.matches(ViewMatchers.withEffectiveVisibility(visibility))
}

And can be used as follows

onView(withId(R.id.progressBar)).isVisible()
onView(withId(R.id.progressBar)).isGone()
