Interesting topic. I started a blog, which is not complete, but has most of
the concepts for what you are looking for:
http://www.baselogic.com/blog/java/testing-activemq-virtualtopics-using-camel-and-junit
I have been working with the Camel and AMQ team on this, and I am close to
have a fully tested solution....
I have a FAT Client that has a Spring MDP, that I want to dynamically switch
the QUEUE destination at runtime.
Here is the unit test for the changing of destinations:
@Test
@DirtiesContext
public void testChangeMessageDestination() throws Exception {
log.info("Send a test message to Table Service");
log.info("***** testChangeMessageDestination()
********************************");
DefaultMessageListenerContainer container =
(DefaultMessageListenerContainer)context.getBean("jmsListener12");
assertNotNull(container);
assertTrue(container instanceof DefaultMessageListenerContainer);
assertEquals("Consumer.12.VirtualTopic.Table.12",
container.getDestinationName());
resultChangeMessageDestination.expectedMessageCount(0);
// Send the test message to make Server Service create our Status
Message
// Message to be sent to 'VirtualTopic.Table.1' , NOT
'VirtualTopic.Table.12'
producerTemplate.sendBody("jms:queue:sendStatusUpdate",
ExchangePattern.InOnly, 1);
// now lets assert that the mock endpoint received messages
resultChangeMessageDestination.assertIsSatisfied();
resultChangeMessageDestination.reset();
log.info("* valid message
received.---------------------------------");
ActiveMQQueue newDestination = new
ActiveMQQueue("Consumer.12.VirtualTopic.Table.1");
container.setDestination(newDestination);
* resultChangeMessageDestination.expectedMinimumMessageCount(4);*
// Send the test message to make Server Service create our Status
Message
// Message to be sent to 'VirtualTopic.Table.1' , NOT
'VirtualTopic.Table.12'
producerTemplate.sendBody("jms:queue:sendStatusUpdate",
ExchangePattern.InOnly, 1);
// now lets assert that the mock endpoint received messages
resultChangeMessageDestination.assertIsSatisfied();
resultChangeMessageDestination.reset();
log.info("* no message received
again.---------------------------------");
newDestination = new
ActiveMQQueue("Consumer.12.VirtualTopic.Table.BAD");
container.setDestination(newDestination);
resultChangeMessageDestination.expectedMinimumMessageCount(0);
// Send the test message to make Server Service create our Status
Message
producerTemplate.sendBody("jms:queue:sendStatusUpdate",
ExchangePattern.InOnly, 1);
// now lets assert that the mock endpoint received messages
resultChangeMessageDestination.assertIsSatisfied();
}
- One of the biggest issues I can seem to understand, is why I get 4+
messages onto the queue from my VirtualTopic.
- I also have some doubts on either the way I am using the the Mocks, or
the Mocks themselves as if I change the expected number of messages
received, I stop getting any messages to those Mocks.
- I also, can not seem to validate the changed name in the *
container.getDestinationName()* call after I change the destination.
