Examples with Event io.lettuce.core.event.Event used on opensource projects

Example 1 with Event

use of io.lettuce.core.event.Event in project lettuce-core by lettuce-io.

the class DefaultClientResourcesUnitTests method testEventBus.

@Test
void testEventBus() {
    DefaultClientResources sut = DefaultClientResources.create();
    EventBus eventBus = sut.eventBus();
    Event event = mock(Event.class);
    StepVerifier.create(eventBus.get()).then(() -> eventBus.publish(event)).expectNext(event).thenCancel().verify();
    assertThat(TestFutures.getOrTimeout(sut.shutdown(0, 0, TimeUnit.MILLISECONDS))).isTrue();
}

Example 2 with Event

use of io.lettuce.core.event.Event in project lettuce-core by lettuce-io.

the class ConnectionFailureIntegrationTests method emitEventOnReconnectFailure.

@Test

    ClientResources clientResources = ClientResources.create();
    RedisURI redisUri = RedisURI.create(defaultRedisUri.toURI());
