Resolving Web Performance Test Result Viewer Playback Issues in Web Performance Tests

You can use several features in Web performance tests to help isolate playback issues in the Web Performance Test Results Viewer. For example, you can use Quick Find to help isolate dynamic parameters that cause the playback to fail in both the Web performance tests playback and the recording log. After the location where a dynamic parameter is being initialized is identified, you can add new extraction rule for it directly from playback. Adding a new extraction rule eliminates playback failures that are caused by dynamic parameters. You can also easily move back and forth between associated parameters in the Web performance tests playback and the Web Performance Test Editor.

Isolate dynamic parameters in playback: Some Web sites and applications use dynamic parameters in one or more of their Web requests. Dynamic parameters can cause your Web performance test playback to fail. You can isolate dynamic parameters in your playback within the Web Performance Test Results Viewer. You can then add an extraction rule to overcome playback issues. For more information, see How to: Add an Extraction Rule from the Web Performance Test Playback.

Go to web request from playback: You can easily move back and forth on a parameter from the Web Performance Test Results Viewer to the Web Performance Test Editor window to help you isolate playback issues.	How to: Jump to Web Request from the Web Performance Test Playback
Add an extraction rule from playback: Some Web sites and applications use dynamic parameters in one or more of their Web requests. Dynamic parameters can cause your Web performance test playback to fail. To avoid playback errors, you can add extraction rules to dynamic parameters in your Web performance test. However, before you add an extraction rule, you first have to locate dynamic parameters.

Resolve Web performance test playback issues caused by dynamic parameters: Some Web sites and applications use dynamic parameters in one or more of their Web requests. A dynamic parameter is a parameter whose value is generated every time that a user runs the application. A dynamic parameter can cause your Web performance test playback to fail because the dynamic value will likely be different every time that the test is run. Therefore, you cannot play back recorded values.	How to: Resolve Web Performance Test Playback Issues Caused by Dynamic Parameters Walkthrough: Correlating Dynamic Parameters
Create a custom recorder plug-in to correlate dynamic parameters: You can use the WebTestRecorderPlugin class to create a custom recorder plug-in if you want to implement code to handle dynamic parameters in a specific fashion.	How to: Create a Recorder Plug-In
