Example 6 with ServiceModel

use of com.yahoo.vespa.service.monitor.ServiceModel in project vespa by vespa-engine.

the class ServiceModelCacheTest method sanityCheck.

@Test

    when(rawSupplier.get()).thenReturn(serviceModel);
    long timeMillis = 0;
    when(timer.currentTimeMillis()).thenReturn(timeMillis);

    ServiceModel actualServiceModel = cache.get();
    assertTrue(actualServiceModel == serviceModel);
    verify(rawSupplier, times(1)).get();
    // Cache hit
    timeMillis += ServiceModelCache.EXPIRY_MILLIS / 2;
    when(timer.currentTimeMillis()).thenReturn(timeMillis);
    actualServiceModel = cache.get();
    assertTrue(actualServiceModel == serviceModel);
    // Cache expired
    timeMillis += ServiceModelCache.EXPIRY_MILLIS + 1;

    when(rawSupplier.get()).thenReturn(serviceModel2);
    actualServiceModel = cache.get();
    assertTrue(actualServiceModel == serviceModel2);
    // '2' because it's cumulative with '1' from the first times(1).
