unit-test-scheduled-async

Test @Scheduled and @Async methods directly without waiting for actual execution. Patterns for unit testing Spring @Scheduled and @Async methods with JUnit 5. Test CompletableFuture results, use Awaitility for race conditions, mock scheduled task execution, and validate error handling — without waiting for real scheduling intervals. Validation checkpoints: Key patterns — complete examples in references/examples.md : Full Maven/Gradle dependencies, additional test classes, and execution count patterns: see references/examples.md . - Call async and scheduled methods directly in tests instead of relying on Spring's async executor or scheduling intervals - Use CompletableFuture.get() with explicit timeouts to wait for async results, and Awaitility.await() for polling-based assertions on state changes - Mock dependencies that async methods call, then verify interactions after completion using Mockito - Test exception handling by catching ExecutionException from CompletableFuture.get() and verifying the underlying cause - Requires JUnit 5, Mockito, Awaitility, and AssertJ; avoid testing actual cron timing or thread pool behavior - Testing @Scheduled method logic - Testing @Async method behavior - Verifying CompletableFuture results - Testing async error handling - Testing cron expression logic without waiting for actual scheduling - Validating thread pool behavior and execution...
