Despite the annual improvement of tools — everything related to Android instrumented testing still can be challenging and requires a lot of attention from engineers.

The goal of this open-source documentation is to make the process of introducing instrumented testing into your team smoother and avoid repeating our mistakes.

RxTest is a Kotlin library for testing RxJava.

Main features

  • Clear tests: write clean, readable and simple tests in scala-test should style.
  • Easy to extend: create custom matchers for complex test cases or just for more readable code.
  • Simple to use: test api same as RxJava assertions you already know.

Nice and simple DSL for Espresso in Kotlin.

Android Espresso made more fluent ☕️

Espresso's consistency makes it really easy to learn.

Want to match a view with a specific id? Use withId(R.id.some_id). Need to match with a piece of text? Use withText(R.id.some_text) or withText("some text). Awesome, consistent and it's very clear what it is you are doing.

However...

After a few hours writing test code you'll find your code being a little bit too verbose. Not anymore.

Why should you need to explicitly specify that you are matching with some text if you are passing in some text as a parameter? Some for the view id, you can already see that it is a view id.

Ristretto allows you to write the same test code as you already write, but less verbose.
