Android testing using Dagger 2, Mockito and a custom JUnit rule
Android testing using Dagger 2, Mockito and a custom JUnit rule Dependency injection is a key concept to get testable code. Using dependency injection it’s easy to replace an object with a mock to change and verify the behavior of a system. Dagger 2 is the dependency injection library used in many Android projects, in this post we’ll see how to take advantage of it to test an Android app. Let’s se
Testing asynchronous RxJava code using Mockito
RxJava is used in many Android applications to manage background tasks, in this post will see how to test this code using Mockito and some RxJava utility classes. The example is written using RxJava 2, the same concepts are available also in RxJava 1 (in the demo project you can find both versions of the same example). Let’s see a simple example, we need a class (created using Retrofit) to execute

To commemorate the launch of Dagger 2 out of SNAPSHOT, I am sharing a demo repo with Dagger 2, Espresso 2 and Mockito: https://github.com/chiuki/android-test-demo Dagger Components Dependency injection allows our app and test obtain different modules.
