Kotlin Testing

Covers the full TDD cycle in Kotlin with Kotest specs, MockK mocking, coroutine testing, and Kover coverage reporting. You get working examples of StringSpec, FunSpec, BehaviorSpec, and DescribeSpec styles, plus a proper RED-GREEN-REFACTOR walkthrough with an email validator. The matchers section is solid for assertions, and the MockK examples show coEvery for suspending functions and verification patterns. Includes Ktor testApplication setup if you're testing HTTP routes. The 80% coverage target with Kover is reasonable, and the examples are copy-paste ready. Good reference if you want idiomatic Kotlin tests instead of fighting with JUnit patterns that don't fit the language.
