Testing with Kotlin
summary
Shows concrete recipes: uses JUnit 5 indexes arguments from 1 to explain parameterized-test differences, replaces JUnit runners with KotlinTest/Kotest StringSpec and Spek for readable output, and swaps Mockito for MockK supports multiplatform or mockito-kotlin extensions. Builds test helpers: factory methods with default args to avoid tedious DI constructors, an extension to invoke ViewModel cleanup (onCleared) in unit tests, and a robot abstraction records rendered view states in order to verify MVI chat flows end-to-end. Examples live in the repo.
