Supersonic Subatomic Mocking: How to test your Quarkus app
summary
Shows concrete test patterns for a Quarkus + Kotlin app: unit tests with MockK for service logic, then promoted to QuarkusTest when a Quarkus cache annotation must be exercised so CDI uses the mock; reveals a Kotlin/JUnit5 gotcha requiring a static BeforeAll (companion object + @JvmStatic). Uses MockK and the Quarkus MockK JUnit5 extension to auto-inject mocks. Demonstrates failing then fixed tests, reports startup timing (demo run ~8s vs expected ~1s), and notes the extension is v0.2.0 with few contributors but functional.
