Perhaps you have some animation or some other background (or foreground) activity that updates your UI on the main thread frequently. This causes the app to never be "quiesce" - at least on this tab.

I couldn't find a way to force the test not to wait to be idle, so we ended up disabling the animation using #ifdef for the UI test target using runtime arguments as described here: https://stackoverflow.com/a/33466038/168996
