Load Tests in Visual Studio

With the help of Visual Studio you can setup a Load Test. A little part of the Load Test is a Web Performance Test (prev. Web Test). A requirement for executing the test again and again without having recording it again is that the ids of the web controls are the same, between postbacks AND IIS restarts. If this is NOT the test will fail, you can solve this by making the web control id constant or maybe you can create an Extraction Rule
