Hello Team , i facing issues with RabbitListenerTestHarness, it is not working. Below is my project structure

Main class

@Component
public class ABC {

@Autowired
private AmqpTemplate amqpTemplate;

@RabbitListener(id="id", queues="${queue}")
public void receiveMessage(String message) {
publishMsg(message);
}

public void publishMsg(String msg){
amqpTemplate.convertAndSend("exchange", "",msg);
}

}
test class

@RunWith(SpringRunner.class)
@SpringBootTest
public class ABCTest {

@Autowired
private RabbitListenerTestHarness harness;

@Autowired
private RabbitTemplate rabbitTemplate;
@Test
public void testSendtoQueue() throws Exception {
ABC listener = this.harness.getSpy("id");
assertNotNull(listener);

LatchCountDownAndCallRealMethodAnswer answer = this.harness.getLatchAnswerFor("id", 1);
doAnswer(answer).when(listener).receiveMessage(any(String.class));

String data = getMockString("src/test/resources/rabbitMQ-data.json");

this.rabbitTemplate.convertAndSend("Queue-name", data);

//assertTrue(answer.await(10));
verify(listener,times(1)).receiveMessage("data");
}
}

and on running above it gives me error as below

Wanted but not invoked:
customPublisherSubscriber.receiveMessageFromResponseQ(
"data"
);

Actually, there were zero interactions with this mock.

i was referring to https://github.com/spring-projects/spring-amqp/blob/master/src/reference/asciidoc/testing.adoc.

I am struggling to understand as i am trying to verify spy object for message received or not, but it is reporting issues related to mock object. Could you please assist me on this.
