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.

Barista introduces a discoverable API for the Espresso features. So, you and all the Android team will write instrumental tests with no effort.

A lightweight RxJava2 wrapper for the Android Firebase client SDK, the user is expected to own the lifecycle of an asynchronous request via RxJava2 Disposable handling, however elements in this library will properly unregister listeners when a Publisher is cancelled, except in the case of value setting where it is only possible to register a listener when making the request. In this case the emitter is checked for it's subscription state.

Whilst the FirebaseDatabase api is mirrored with RxFirebaseDatabase it only really uses the database reference, this is so that the reference hierarchy can easily be traversed through child and parent elements. Methods requiring FirebaseDatabase obtain this from the DatabaseReference and allow you to chain further requests by returning itself.

This library depends on RxTasks and RxJava2 to provide appropriate api responses. Therefore asynchronous responses will return, Single, Completable and Flowable respectively.
