Coroutine Testing

Test suspend functions.

Why Coroutine Testing is Special

Coroutines run asynchronously and may use delays. Tests need controlled time and a way to wait for suspend functions to finish.

The kotlinx-coroutines-test library provides exactly this.

Add the coroutines test artifact to your test dependencies.

dependencies {
    testImplementation("org.jetbrains.kotlinx:kotlinx-coroutines-test:1.8.1")
}
