MockK is a mocking library for Kotlin providing a Kotlin-first DSL for creating mocks, stubbing behavior, and verifying calls. It supports coroutines, Android unit and instrumented tests, and BDD-style aliases.
Use cases
- mock dependencies in Kotlin unit tests
- stub and verify method calls with a Kotlin DSL
- mock suspend functions and coroutines
- write BDD-style tests in Kotlin
- mock classes in Android instrumented tests
- mock Spring beans in Spring Boot Kotlin apps
When to choose
- you write Kotlin or Android tests and need idiomatic mocking
- you need to mock coroutines, objects, or final classes
- you want strict mocks with verification by default
When to avoid
- you are writing pure Java projects (Mockito may fit better)
- you need mocking outside the JVM ecosystem
