Do you know some free tool that allows load testing of a Silverlight application? After searching at web I know that two good free load testing tools are JMeter and LoadUI, but I am not sure if they work good with a Silverlight application.
For now I pretend to do only whole-app (system) testing, but if I see it worth to do unit load testing, I will consider it too.
I have to test the response time of several features in the client (the Silverlight app), including the search engine. For that, I still don't know what is the the better approach. I don't know if, for example, the better approach would be to simulate traffic on the server or just altering the responsiveness of the server and determine the impact of server-side slowdowns on the client. The system must support at least 300 users.
After that, I would like to perform stress testing as well, although it is not a essential thing to do.
