If you have used Visual Studio for load testing, you may
have experienced playback errors from a recorded scenario.
This happens more often when you test a highly dynamic
website or a web application with enhanced security. To resolve these issues,
Microsoft troubleshooting instructions recommend performing manual correlation,
including finding dynamic parameters and creating
extractors. Unfortunately, the
manual correlation process is difficult, requires experience, and does not always work.
StresStimulus has the #1 auto-correlation engine on the
market. It substantially reduces test development time and
works with all web frameworks including the toughest-to-test

Dynamics CRM and
Until recently these benefits were available exclusively to
StresStimulus users. Starting with version 4.6, Visual
Studio users can also start saving time on developing web tests and extending testing coverage of applications that are difficult or virtually impossible to test.
How It Works
First, record your test scenario in StresStimulus. It will correlate your dynamic parameters automatically, reducing the amount of manual correlation
required in Visual Studio by an order of magnitude. Then export the web test to a file and import it to Visual Studio where you can continue testing in a familiar and robust testing environment integrated into your company's application lifecycle workflow. Web Test Generator for Visual Studio provides a runtime module that ensures errorless test
