Ah, Wonderful TDD — Peace of Mind for Apps and Engineers
summary
Presents concrete TDD rules (red–green–refactor loop plus three strict rules) and demonstrates them by implementing a Janken (rock–paper–scissors) class with three JUnit unit tests, iterating until all tests pass. Recommends running TDD on the local JVM (using trampoline scheduler for RxJava tests), reserving Espresso/Robolectric for UI happy‑path checks, and shows MVVM separation, testing LiveData observers, and dependency injection (constructor or Dagger2) to enable faster, safer refactoring.
