IdlingUiController

Artifact: androidx.test.espresso:espresso-core

Kotlin |Java

interface IdlingUiController : UiController

Similar to UiController but with one additional method that enables getting an instance of IdlingResourceRegistry. For instance, the registry can then be used by androidx.test.espresso.ViewAction to register and unregister idling resources before and after performing the actual action.

This interface used for Espresso internals and shouldn't be called by external users.
