Comprehensive Kotlin testing patterns for writing reliable, maintainable tests following TDD methodology with Kotest and MockK. Writing new Kotlin functions or classes Adding test coverage to existing Kotlin code Implementing property-based tests Following TDD workflow in Kotlin projects Configuring Kover for code coverage 1. Identify target code — Find the function, class, or module to test 2. Write a Kotest spec — Choose a spec style (StringSpec, FunSpec, BehaviorSpec) matching the test scope 3. Mock dependencies — Use MockK to isolate the unit under test 4. Run tests (RED) — Verify the test fails with the expected error 5. Implement code (GREEN) — Write minimal code to pass the test 6. Refactor — Improve the implementation while keeping tests green 7. Check coverage — Run ./gradlew koverHtmlReport and verify 80%+ coverage The following sections contain detailed, runnable examples for each testing pattern: Kotest specs — StringSpec, FunSpec, BehaviorSpec, DescribeSpec examples in Kotest Spec Styles Mocking — MockK setup, coroutine mocking, argument capture in MockK TDD walkthrough — Full RED/GREEN/REFACTOR cycle with EmailValidator in TDD Workflow for Kotlin Coverage — Kover conf
