Execution of GUI Vusers as LoadRunner scripts (LR-QTP)

• Measure end-to-end user experience during the load test
• Run business process that could not be scripted using VuGen but can be scripted using QTP

LoadRunner can integrate QuickTest scripts into a load testing scenario in the form of GUI Vuser scripts. These scripts, that have already been designed and debugged in QuickTest, can be used as the basis of your load test.

The main uses of running QuickTest scripts in LoadRunner are:

• To check how your application's functionality is affected by heavy load
• To measure the response time that a typical user experiences on the client side while your application is under load (end-to-end response time)

For example, you can add QuickTest scripts to specific points in a LoadRunner scenario to confirm that the application's functionality is not affected by the extra load at those sensitive points.

Another advantage of using a GUI Vuser script as part of your LoadRunner scenario is that the GUI Vuser script runs on your screen during the scenario, enabling you to watch the actual steps executed by the Vuser in real time.

As mentioned above, using QTP scripts may help when the application is not supported in the LoadRunner protocols and can be scripted using QTP.
