Introducing the Virtual User Generator (VuGen) The VuGen Window at a Glance Developing a Vuser Script Example- HP WebTours Website Tree View and Script View


Introducing the Virtual User Generator (VuGen)

HP’s tool for creating Vuser scripts is the Virtual User Generator, VuGen.

During recording VuGen monitors the client end of the database and traces all the requests sent by the user and received from the user, to the server.

During playback, Vuser scripts communicate directly with the server by executing calls to the server API.

When a Vuser communicates directly with a server, system resources are not required for the client interface. This allows a large number of Vusers to run simultaneously on a single workstation, and few testing machines are required to emulate large server loads.

HTML based: Records script for every user action that is performed during recording

URL based: Records each and every browser request to the server and resources received from the server.

HTML mode is recommended for browser applications while URL mode is recommended for non-browser applications.

web based applications e.g. Web/Oracle NCA.
