RabbitListenerTestHarness does not support repeatable @RabbitListener annotations

[ashvydkyi]

Hi!
I've created SpringBootTest to test Rabbit Listener. While using the @RabbitListenerTest annotation, I want to use the capture advice.

@SpringBootTest(classes = StringMessageListenerTest.TestConfiguration.class)
@RabbitListenerTest(spy = false, capture = true)
public class StringMessageListenerTest {

    @Configuration
    public static class TestConfiguration {
        @Bean
        public TestRabbitTemplate testRabbitTemplate() throws IOException {
            return new TestRabbitTemplate(mockConnectionFactory());
        }

        @Bean
        public ConnectionFactory mockConnectionFactory() throws IOException {
            ConnectionFactory factory = mock(ConnectionFactory.class);
            Connection connection = mock(Connection.class);
            Channel channel = mock(Channel.class);
            willReturn(connection).given(factory).createConnection();
            willReturn(channel).given(connection).createChannel(anyBoolean());
            given(channel.isOpen()).willReturn(true);
            return factory;
        }

        @Bean
        public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory() throws IOException {
            SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
            factory.setConnectionFactory(mockConnectionFactory());
            return factory;
        }

        @RabbitListener(id = "string1", queues = "queue1")
        public void onMessage(String string) {
        }

        @RabbitListener(id = "string2", queues = "queue2")
        @RabbitListener(id = "string3", queues = "queue3")
        public void onRepeatedMessage(String string) {
        }
    }

    @Autowired
    private RabbitListenerTestHarness rabbitListenerTestHarness;
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    void whenRabbitListenerAnnotationUsed_shouldHandleStringSuccessfully() throws Exception {
        this.rabbitTemplate.convertAndSend("queue1", "string");

        var invocationData = rabbitListenerTestHarness.getNextInvocationDataFor("string1", 5, TimeUnit.SECONDS);
        var message = (String) invocationData.getArguments()[0];

        assert message.equals("string");
    }

    @Test
    void whenRepeatedRabbitListenerAnnotationUsed_shouldHandleStringSuccessfully() throws Exception {
        this.rabbitTemplate.convertAndSend("queue2", "string");

        var invocationData = rabbitListenerTestHarness.getNextInvocationDataFor("string2", 5, TimeUnit.SECONDS);
        var message = (String) invocationData.getArguments()[0];

        assert message.equals("string");
    }
}

It seems that like org.springframework.amqp.rabbit.test.RabbitListenerTestHarness.CaptureAdvice doesn't support repeatable annotation processing. Am I missing something?
Thanks in advance.

It's a bug; the CaptureAdvice only considers capturing data for methods with a single annotation.

I'll convert this to an issue.
