Use this repository a starting point to complete Android code katas.
Join my newsletter for updates about my upcoming book with Android katas.
The master branch has Robolectric preintegrated.
Note: To become comfortable with integrating Robolectric, use the "Hello, Robolectric" chapter of the Android Activity Book or my Pocket Guide to TDD with Robolectric (coming soon!) as a separate kata.
Simply import into Android Studio using the "Import Non-Android Studio project" option and selecting the top-level build.gradle file.
In Android Studio, open the "Build Variants" tab and select "Unit Tests" as the "Test Artifact" and debug from the drop down next to app.
Now that the project is set up, ensure the tests run.
Create a run configuration to run the tests from the IDE (my preferred method). Click the plus button, select "junit," and match the configuration shown here:
You can also run the tests from the command line, using ./gradlew check.
Now that the project is configured, you're ready to work though some katas!
If you get this error when using your run configuration, you used the wrong module name in your classpath when you configured it.
10:15:14 AM Error running Unnamed: No junit.jar in Module 'AndroidKatas' runtime scope
Change it to use app instead of AndroidKatas.

It means that you forgot to select "Unit Tests" as the "Test Artifact" in the "Build Variants" window.
