Virtual User (VU) Group

A virtual user (VU) group executes either a single script or workflow in Eggplant Performance. Tests may contain multiple VU groups, thus enabling simultaneous execution of many different scripts and workflows within a single test.

Each VU group possesses many properties and runtime settings, that describe how its VUs operate during test execution. VU group properties include:

  • The script, or workflow, to execute.
  • The number of VUs.
  • The number of injectors to use and the distribution of VUs across injectors.
  • The transaction rates and speed of playback.
  • The number of iterations.
  • The group specific data sources available and how they should be accessed.
