Assertion error while running test with LatchCountDownAndCallRealMethodAnswer from RabbitMQ - junit

Question

I have a listener test, where i post a message in a parallel thread and check with LatchCountDownAndCallRealMethodAnswer if the all were processed successfully. Running the test alone, it works perfectly, however if you run all other tests together, it fails because it failed to leave the counter at zero, but the listener received and processed the message normally. Does anyone have any ideas?
My Test Class
#RunWith(SpringRunner.class)
#SpringBootTest
#RabbitListenerTest
#ActiveProfiles("test")
public class EventListenerTest {
EventListener eventListener;
#Autowired
protected RabbitListenerTestHarness harness;
#Autowired
private EventStoreRepository repository;
#SpyBean
private DomainEventPublisher publisher;
#Before
public void setUp() {
MockitoAnnotations.initMocks(this);
DomainRegister.setDomainEventPublisher(publisher);
eventListener = this.harness.getSpy("eventListenerId");
}
#Test
public void storeEventsListenerTest() throws Exception {
LatchCountDownAndCallRealMethodAnswer answer = new LatchCountDownAndCallRealMethodAnswer(1);
doAnswer(answer).when(eventListener).storeEvents(any(BalanceReserved.class));
publisher.publish(new BalanceReserved("12233", 150.0, BigDecimal.ZERO), "");
assertTrue(answer.getLatch().await(10, TimeUnit.SECONDS));
verify(eventListener, times(1)).storeEvents(any(BalanceReserved.class));
}
#After
public void tearDown() {
DomainRegister.setDomainEventPublisher(null);
reset(eventListener);
repository.deleteAll();
}
}
Error
java.lang.AssertionError

If you have other tests using the same queue, you need to shut down the application context for each test so the test's listeners are stopped. By default, the Spring Test framework caches the application context for reuse. This will cause other tests to "steal" messages.
Add #DirtiesContext to each test class that uses #RabbitListeners, to tell the test framework to shutdown the context.
