One of my favorite tools for creating polished apps is Robolectric, which allows you to unit test directly in your IDE — fancy debugging and everything.
I’ve been kicking around the idea for a while to create katas to practice technique and help others start out with the tool. I didn’t want them to go through the same pain of spending several minutes (or hours) trying to piece together disparate suggestions for how to test something simple!
- Presence of views and non null-ness
- Correct string and drawable resources
- Presence of fragments
- Button functionality
- Toast functionality
- Starting a new activity
It’s designed so that you can do it over and over again to get comfortable with the basics of unit testing in Android Studio. There’s also a solution.
Hope you find it useful!
P.S. If you want to practice your own katas without fussing with the integration of Robolectric — check out: http://github.com/colabug/AndroidKatas.
