To write Kotlin Multiplatform tests for JVM and iOS, apply standardized testing patterns across commonTest, androidUnitTest, and iosTest using kotlin.test and kotlinx-coroutines-test to verify UseCases, ViewModels, and Ktor repositories.

You should avoid MockK in commonTest because it lacks full Kotlin Multiplatform support; instead, use Ktor MockEngine for network mocking and standard kotlin.test assertions to ensure cross-platform test compatibility.

The best way to test Ktor repositories in a Kotlin Multiplatform module is using Ktor MockEngine to mock HTTP responses, combined with deterministic testing patterns like injected clocks and runTest for coroutine execution.

To test ViewModels with coroutines in KMM without thread sleep, use kotlinx-coroutines-test with runTest and setMain dispatcher to control asynchronous execution deterministically across commonTest and platform-specific test suites.

Yes, this KMM testing approach supports both androidUnitTest and iosTest scenarios by providing reusable cross-platform testing patterns that standardize coroutine dispatcher setup and HTTP mocking across JVM and Native targets.
