VuGen 11.5 Scripting for Web

Course Summary

The Virtual User Generator (VuGen) is a scripting tool used to record and run user actions on the application to be load tested. This course focuses on planning, creating and enhancing Virtual User (Vuser) scripts using VuGen in the Web environment. All topics are supported by hands-on labs designed to provide you with the knowledge necessary to create scripts in the Web environment.

Intended Audience

  • Quality Assurance Engineers

  • Users of LoadRunner who need to create scripts to load test their Web applications.

At the end of the course, you will be able to:

  • Record scripts in the Web environment using VuGen
  • Measure steps and business processes using transactions
  • Parameterize scripts to vary user input data
  • Customize scripts by adding VuGen and basic C functions
  • Correlate scripts to process server-generated data
