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

Example 1 with EventBus

use of io.lettuce.core.event.EventBus 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 EventBus

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

the class ClientMetricsIntegrationTests method testMetricsEvent.

@Test
@Inject
void testMetricsEvent(RedisClient client, StatefulRedisConnection<String, String> connection) {
    Collection<CommandLatencyEvent> events = new LinkedBlockingQueue<>();
    EventBus eventBus = client.getResources().eventBus();
    MetricEventPublisher publisher = (MetricEventPublisher) ReflectionTestUtils.getField(client.getResources(), "metricEventPublisher");
    publisher.emitMetricsEvent();
    Disposable disposable = eventBus.get().filter(redisEvent -> redisEvent instanceof CommandLatencyEvent).cast(CommandLatencyEvent.class).doOnNext(events::add).subscribe();
    generateTestData(connection.sync());
    publisher.emitMetricsEvent();
    Wait.untilTrue(() -> !events.isEmpty()).waitOrTimeout();
    assertThat(events).isNotEmpty();
    disposable.dispose();
}

Example 3 with EventBus

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

the class DefaultClientResourcesUnitTests method testProvidedResources.

@Test
void testProvidedResources() {
    EventExecutorGroup executorMock = mock(EventExecutorGroup.class);
    EventLoopGroupProvider groupProviderMock = mock(EventLoopGroupProvider.class);
    Timer timerMock = mock(Timer.class);
    EventBus eventBusMock = mock(EventBus.class);
    CommandLatencyCollector latencyCollectorMock = mock(CommandLatencyCollector.class);
    NettyCustomizer nettyCustomizer = mock(NettyCustomizer.class);
    AddressResolverGroup<?> addressResolverGroup = mock(AddressResolverGroup.class);
    DefaultClientResources sut = DefaultClientResources.builder().eventExecutorGroup(executorMock).eventLoopGroupProvider(groupProviderMock).timer(timerMock).eventBus(eventBusMock).commandLatencyRecorder(latencyCollectorMock).nettyCustomizer(nettyCustomizer).addressResolverGroup(addressResolverGroup).build();

    assertThat(sut.eventBus()).isSameAs(eventBusMock);
    assertThat(sut.nettyCustomizer()).isSameAs(nettyCustomizer);
    assertThat(sut.addressResolverGroup()).isSameAs(addressResolverGroup);
    assertThat(TestFutures.getOrTimeout(sut.shutdown())).isTrue();
    verifyNoMoreInteractions(executorMock);
    verifyNoMoreInteractions(groupProviderMock);
    verifyNoMoreInteractions(timerMock);
    verify(latencyCollectorMock).isEnabled();
    verifyNoMoreInteractions(latencyCollectorMock);
}

Example 4 with EventBus

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

the class DefaultClientResourcesUnitTests method mutateResources.

@Test
