问题 would someone be able to show me how to make the getMovies function in this viewModel testable? I can't get the unit tests to await the coroutines properly.. (1) I'm pretty sure I have to create a test-CoroutineScope and a normal lifeCycle-CoroutineScope, as seen in this Medium Article. (2) Once the scope definitions are made, I'm also unsure how to tell getMovies() which scope it should be using given a normal app context or a test context. enum class MovieApiStatus { LOADING, ERROR, DONE }
