Vuser Generator
Vuser Generator is the Script generation component of LoadRunner. This component has two main things and are described below:
Vusers: In the scenario, LoadRunner replaces human users with virtual users or Vusers. When you run a scenario, Vusers emulate the actions of human users working with your application.
While a workstation accommodates only a single human user, many Vusers can run concurrently on a single workstation. In fact, a scenario can contain tens, hundreds, or even thousands of Vusers.
Vuser Scripts: The actions that a Vuser performs during the scenario are described in Vuser script. When you run a scenario, each Vuser executes a Vuser script. The Vuser scripts include functions that measure and record the performance of your application’s components.
Controller: You use the HP LoadRunner Controller to manage and maintain your scenarios. Using the Controller, you control all the Vusers in a scenario from a single workstation.
Load Generator: When you execute a scenario, the Controller distributes each Vuser in the scenario to a load generator. The load generator is the machine that executes the Vuser script, enabling the Vuser to emulate the actions of a human user.
Performance analysis: Vuser scripts include functions that measure and record system performance during load-testing sessions. During a scenario run, you can monitor the network and server resources. Following a scenario run, you can view performance analysis data in reports and graphs.
