during the meeting Ori suggested ANTS performance profiler for our purpose. I've looked some basic tutorial and ANTS does it seems to be a profiler, this is not what i was asking for. What i need it's an instrument or a way to make some automated operation in order to simulate the load generated by different users working at the same time.
I've done some test stress with Visual Studio 2010 Test Project, recording a Web Perfomance Test and then adding to the project some Load Test wich takes care of simulate different virtual users (on the base of the Web Performance Test recorded before).
The problem is that analizing the xml that VWG server send to the browser in response to a change in a textbox i've seen a difference between:
-the real xml that the server send to the browser (sniffed with Fiddler 2);
-the xml the server send to the browser in the Visual studio Test Project Simulation;
In particular visual studio simulation seems to send back the whole form instead of just sending the text box that have changed text.
This makes me think that this simulation doesn't work properly. What i was asking to you is what kind of tool are you using to make automated load test. Do you know if Visual Studio Load Test work properly with VWG?
