This topic explains how to use Virtual Table Server (VTS) with supported script types.

VTS overview

You can use VTS with VuGen, DevWeb, and TruClient scripts. Scripts that you upload can fetch data from a VTS server in the same way as in other OpenText Performance Engineering products.

VTS (Virtual Table Server) is a web-based application that works with Vuser scripts. VTS offers an alternative to standard VuGen parameterization.

When you use standard parameterization, each Vuser is assigned parameter values from a dedicated set of values - parameter values are not shared between Vusers. In contrast, VTS enables you to assign parameter values from a single set of parameter values to multiple Vusers. This may enable you to more accurately emulate a real-user environment.

VTS includes a table that contains parameter values that can be used by your Vuser scripts. The VTS table is composed of columns and rows. Each column represents a set of values that can be used by a specific parameter in your Vuser scripts. The cells within a column contain the actual values of the parameter.

Install VTS

To download and install VTS, go to the Virtual Table Server page in the AppDelivery Marketplace.
