Testing Juno Android app with ❤️: CI, Unit, Integration & Functional (UI) tests. 100% Kotlin, 90%+ RxJava, Spek, JUnit, DSL for UI tests.

TL;TR: how we write unit tests for Android project in Kotlin and RxJava, why we prefer Spek over JUnit and Spock, how we isolate our code from Android Framework, how tests that need Android Runtime work and why we don’t use Robolectric, how our UI tests are organized and why we don’t hit real servers. You may ask why two speakers? Because Artem is one of the developers and Orkhan is our QA who actively automates his work.
