Integration test with Spring-context doesn't receive RabbitMQ messages - rabbitmq

Question

RabbitMQ MessageConsumer doesn't receive the published message
I'm writing an integration test which should received a message from a queue and do the processing. But the consumer simply doesn't receive the message.
When I manually inject the dependencies - without Spring context, things works fine. But when I use SpringContext, the consumer doesn't receive the message.
The SpringInfraConfig.class loads values from environment variables. To 'emule' the the environment I'm usging the class EnvironmentVariables from this library. The env variables are loaded fine - checked running debug.
NOTE when I mention without SpringContext works fine, I wasn't using the Environment Library too.
To publish the message into RabbitMQ queue, I'm doing it 'manually' on test method. The message is published fine. I wrote a consming test code before call my real testing class. It's a simple raw consumer overriding DefaultConsumer#handleDelivery with a sysout to print the incoming message. Works.
When I test using my real testing class - MessageConsumerServiceImpl.class it just log starting consuming from queue and the test ends.
Something pretty weird occurs when I debug and step into all methods - the message is received and in the middle of processing it ends up without completing all calls - the test just stops, no error are threw too.
Another weird thing is - enabling the RabbitMQ management plugin, there are no queues, exchange, channels or even a connection open. I checked this in debug running while stoped into a break-point.

I have no more idea about the problema. Any help is welcome.
Thanks in advance
UPDATE
I wrote my test again making it simplier. I wrote one code with Spring-context and env stuff and another one without Spring-context and env stuff. BOTH DIDN'T worked.
So, for testing porpuse I coded a simple Thread#sleep() and guess what, BOTH tests worked!
I think the cause is the RabbitMQ DefaultConsumer instanciate a new Thread for consuming messages, what releases the main testing Thread and it got stoped. Since main Thread has been stoped all others get stopped too.
So I think we got a synchronism test problem here.
It's possible to get a failing test if the test code checks database value which should be inserted in exection but in the checking time it was not processed yet?

Answer 1

First of all - you don't have any logging enabled so it's hard to say what is really going on.
Is Spring Boot an option for you? It has built-in logging support. Or are you using just *context library on purpose?
