Load testing WCF operations.

we have requirement that we need to test the wcf operations in load environment to analyse performance of server.

I have developed test cases for wcf operations. Each Test case executes Connect(which connects to application, after that only we can able to execute other operations) so each test case has a dependancy on connect TC. I need to simulate a load pattern like , 20 users connect using testuser1 configuration(configured in xml) and do some wcf operations & 30 users connect using testuser2 and do some wcf operations. i dont want to develop seperate TC for testuser1 & testuser2 . The only one TC connect should be able to connect to Application using different credentials , is it possible . I have used Data driven approach & it didnt worked out for me. please suggest something.

There are few tools out there but I would recommend to use WCFStorm. It supports Functional and performance both types of testing. Try it out. The WCFStorm LITE version is completely free but to get more features you can buy a license.
