val scenario = launchFragmentInContainer {
    TitleScreen().also { fragment ->
        fragment.viewLifecycleOwnerLiveData.observeForever { viewLifecycleOwner ->
            if (viewLifecycleOwner != null) {
                Navigation.setViewNavController(
                    fragment.requireView(),
                    mockNavController
                )
