SpringScheduling @Scheduled Anotasyonu Unit Test

Örnek

Kod şöyle olsun

@Component
public class MyScheduler {

    private final MyService myService;

    @Scheduled(fixedDelayString = "${app.scheduler.delay-ms}")
    public void run() {
        myService.call();
    }
}

Şöyle yaparız

@ExtendWith(SpringExtension.class)
@SpringBootTest(
  classes = { MyApplication.class, 
              MySchedulerIntegrationTest.MySchedulerTestConfig.class },
  properties = {
    "app.scheduler.delay-ms=200"
  })
@ActiveProfiles("local")
class MySchedulerIntegrationTest {

  // Dependency injected into scheduler, we mock it to verify is being called.
  @MockBean
  private MyService myService; 

  @Test
  void shouldStartScheduler() {

    await().atMost(300, TimeUnit.MILLISECONDS)
      .untilAsserted(() -> {
        verify(myService, times(2)).call();
      });
  }

  @Configuration
  static class MySchedulerTestConfig {
    // If you need to mock anything in your context, add here using @MockBean.
  }
}
