Introducing Virtual User Generator

Welcome to the Virtual User Generator.

Virtual User Generator (VuGen) is a primary tool for creating testing scripts that emulate the behavior of real users on your system.


When testing or monitoring an environment, you need to emulate the true behavior of users on your system. Micro Focus testing tools emulate an environment in which users concurrently work on, or access your system.

To perform this emulation, the human is replaced with a virtual user, or a Vuser. The actions that a Vuser performs are typically recorded in a Vuser script.

You use VuGen to develop a Vuser script by recording a user performing typical business processes. The Vuser scripts let you emulate real-life situations.

Use VuGen scripts to test your environment

You use the scripts created with VuGen in conjunction with other Micro Focus products, as follows:

  • LoadRunner, a tool for performance testing, stresses your entire application to isolate and identify potential client, network, and server bottlenecks. Learn more and get a free trial here: LoadRunner Home.

  • StormRunner Load (SRL) is a cloud-based load testing solution that allows Agile development teams to create cost effective, extremely scalable tests. If your application under test is accessible from the internet, you can use SRL to store, manage, and execute your scripts in the cloud, enabling you to rapidly scale to 1 million Vusers or more.

  • Performance Center implements the capabilities of LoadRunner on an enterprise level. Learn more and get a free trial here: Performance Center Home.

  • Application Performance Management (APM) helps you optimize the management and availability of business applications and systems in production. VuGen is used in conjunction with the following APM components:

    • Business Process Monitor (BPM) software is a synthetic monitoring solution that simulates business transactions—whether or not real users are active. You use VuGen to create scripts for BPM, in order to reuse assets in testing and production environments. Learn more here: Business Process Monitor Home.
    • Real User Monitor (RUM) software monitors application performance and availability on business critical application services, for all users. You use VuGen to capture and replay user sessions, and to create test scripts that reflect real user behavior. Learn more and get a free trial here: Real User Monitor Home.
  • AppPulse Active enables you to monitor applications across traditional, mobile, virtualized, and cloud environments. You can use VuGen to record scripts for AppPulse Active, across a range of protocols. The scripts are imported into AppPulse Active and used for availability and performance monitoring, by automatically reproducing the activity of the user.
