FragmentScenario.FragmentAction

public static interface FragmentScenario.FragmentAction

androidx.fragment.app.testing.FragmentScenario.FragmentAction<F extends androidx.fragment.app.Fragment>


FragmentAction interface should be implemented by any class whose instances are intended to be executed by the main thread. A Fragment that is instrumented by the FragmentScenario is passed to perform(F) method.

You should never keep the Fragment reference as it will lead to unpredictable behaviour. It should only be accessed in perform(F) scope.

Summary

Public methods
