Virtual User Types

Eggplant Performance virtual users are available in a variety of types with each type being suited to a particular technology. For example, you would use web virtual users to emulate web browser clients.

Virtual user scripts differ in structure and language depending upon the virtual user type. For example, web virtual users employ either Java or C#, whereas Citrix virtual users use C#. However, all virtual user scripts share access to a common set of functions or methods. Eggplant Performance virtual user types are implemented using the object oriented programming paradigm. Underlying each virtual user type is a base set of classes that provide common functionality.
