How to test throughput of application using rabbitmq?

I have application that uses rabbitmq to queue messages for other parts of ecosystem. I would like to do some performance testing and tuning, but just on my part (the program). So I guess I would like to somehow "mock" away the rabbitmq server, but without changes to my application.

Is there something like dummy rabbitmq server that just accepts all messages and throws them away immediately? Or can I configure actual rabbitmq in that way?
