How can I test multiple fake users accessing my WCF service?

Question

Hello

I'm building a WCF service I'm concerned about performance and scalability.

In order to test multiple users accessing my WCF Service, what should I do?

• create a Thread Pool to run separated threads which in turn access the same WCF method?
• use a testing software tool to simulate these fake users?

I would much rather use some stress testing tool to not reinvent the wheel. It will probably be easier to maintain and such tools may provide for mechanisms to (on a later stage) move your calling clients to several machines etc. Also, they may provide a better way of analyzing the data.

Here is one free WCF load test tool, has several downloads but not a high rating. I would at least check it out before you writer your own.
