Kotlin and Android Development featuring Jetpack

Add More UI Tests

Create the GameFragmentTests class just like you did with PickPlayersFragmentTests, adding it to the androidTest folder of your project. Then, once again add the activityScenarioRule and annotate the class with @RunWith(AndroidJUnit4::class). In addition, add a second annotation called @ExperimentalCoroutinesApi. This annotation allows us to use, without a warning, the runBlockingTest TestCoroutineScope. This is a handy scope to use (for tests only) because it allows us to call suspend functions while skipping any delays in our code. We’re using it here for our @Before function startNewGameBeforeEachTest, as running this function normally causes timing issues with starting a game and checking values.
