Using Fiddler with Visual Studio Team System (VSTS) 2010

When business processes are recorded from VSTS only the requests are captured which might be problematic during correlation. That problem can be overcome by using open web debugging proxy – Fiddler.

Fiddler acts as a web proxy between any web browser and the application under test recording all requests issued by the browser. Each request is recorded witch its response which vastly simplifies correlation process.

Fiddler session can be saved as a *.saz file which will preserve all request\response data and probably more interestingly as a VSTS WebTest.

Following posts will attempt to guide you though the whole process of recording and correlating VSTS WebTests.

1. Recording the script
2. Saving the script
3. Opening recording session in Fiddler and VSTS
4. Adding comments and transactions to the WebTest
5. Correlating the script
• Correlating session ID
• Correlating dynamic parameters
• Identifying and locating dynamic values
• Add extraction rules to extract dynamic values from server response
• Replacing dynamic parameters
6. Script data parametrisation
7. Parametrising environment URL
8. Developing custom extraction rules
