AndroidJUnit4

class AndroidJUnit4 : Runner, Filterable, Sortable

kotlin.Any
↳	org.junit.runner.Runner
	↳	androidx.test.runner.AndroidJUnit4

Aliases the current default Android JUnit 4 class runner, for future-proofing. If future versions of JUnit change the default Runner class, they will also change the definition of this class. Developers wanting to explicitly tag a class as an Android JUnit 4 class should use @RunWith(AndroidJUnit4.class)
