Assert for asynchornous one-way messaging

Hi,

I am wondering if anyone could provide any ideas or experience with asserting a test request where there is no response from consumer. I am testing an asynchronous JMS implementation where the end-point application has a JMS listener that consumes messages from a topic, but does not provide any response message. Upon consuming a message the application performs various database inserts/updates - which I assert in a JDBC test step, however I would like to include some kind of assertion upon consumption of the message itself - any ideas?

Thanks,
Kuba
