`About Espresso`

Espresso is an open-source framework for Android applications developed by Google.
Espresso automatically synchronizes your test actions with the user interface of your application.
It ensures the activities are started before the tests are run.
It also ensures all the tests are run before the background activity is completed.

`Espresso has 3 basic components`

FIND-SOMETHING ----> DO-SOMETHING ----> CHECK-SOMETHING

ViewMatchers -> Finding a view in the current view hierarchy.
ViewActions -> Performing the actions on the view.
ViewAssertions -> Check something by asserting a value.
