Espresso is a great tool to test our Android apps via instrumental tests. With them, we can mimic user actions like clicking a button, scrolling a list, selecting an item on a spinner or swiping on a pager. Then, we can assert that a text appears in the screen, an image is visible or invisible, or a button is enabled or not.

On the other hand, if you tried Espresso, you’ll agree that its API is not discoverable.
