How to test ServerEndPoint, ClientEndPoint?

I have implemented ServerEndPoint and ClientEndPoint, how can i test it? For example, i have Connection wrappers over Session and i want to test it behavior which depends on session data, also i want to test messaging between client and server. Note that i don't have any war or any of application configuration such as web.xml, web-sockets infrastructure going to be used in another place, all what i have is mapped ServerEndPoint and ClientEndPoint implementations.
