In Visual Studio Team Edition there is a load test tool where you can select unit tests, integration tests etc... to form scenarios which are then used in a load test session with different configurations for example varying usage levels.
Looking at for example the NUnit framework, it would be possible to develop a form of such a tool, along with a base load testing code base, but I was interested if anyone knows of any open source project which has has already done a similar thing which could then be of use for this situation and possibly extended?
Cheers for now,
Andrew
