Performance Testing Tool for ZMQ socket library?

My linux based project is in testing phase, we have heavily used ZMQ socket library in code & created dynamic library (.so files).

Is there any freeware or trial (licensed) testing tools available for testing of ZMQ Socket, Which can create various unit test cases, performance test case for ZMQ Socket library ?

If any testing tool will able to load dynamic library (.so files), it will be great help for me for doing performance testing ?

Thanks in advance for all your suggestion.
