Best Practices for Unit Testing in Kotlin
summary
Shows how to write idiomatic unit tests in Kotlin by using Kotlin data classes for test fixtures to get concise, readable failures, preferring constructor injection and small interfaces to avoid brittle static-heavy code, and avoiding starting the Spring context in unit tests (reserve Spring test annotations for integration tests) to speed setup and reduce resource use. Recommends using expressive assertion libraries and careful mocking to keep tests fast and easy to diagnose.
