Usage

From source file:org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainerTests.java

@Test
public void testContainerNotRecoveredAfterExhaustingRecoveryBackOff() throws Exception {
    SimpleMessageListenerContainer container = spy(
            new SimpleMessageListenerContainer(mock(ConnectionFactory.class)));
    container.setQueueNames("foo");
    container.setRecoveryBackOff(new FixedBackOff(100, 3));
    container.setConcurrentConsumers(3);
    doAnswer(invocation -> {/*from w w w  . j a  v  a 2  s  .c  o  m*/
        BlockingQueueConsumer consumer = spy((BlockingQueueConsumer) invocation.callRealMethod());
        doThrow(RuntimeException.class).when(consumer).start();
        return consumer;
    }).when(container).createBlockingQueueConsumer();
    container.afterPropertiesSet();
    container.start();

    // Since backOff exhausting makes listenerContainer as invalid (calls stop()),
    // it is enough to check the listenerContainer activity
    int n = 0;
    while (container.isActive() && n++ < 100) {
        Thread.sleep(100);
    }
    assertThat(n, lessThanOrEqualTo(100));
}
