Android Unit Testing Part IV: Mocking
This is the third of a four part series on Android Unit Testing. In the last two articles I discussed the general principles of having good tests and the way to run Android tests on JVM making them fast and how to make your code less coupled. This article will explain how to make tests isolated. We need to mock a dependency, inject it, and then modify our test to indicate that we are not...
