### System Verification Test Overview

System Verification Test (SVT) is a full function, full hardware environment test to utilize video device drivers. In Function Verification Test (FVT), only one application is run on OS/2, while in SVT, multiple applications are run simultaneously, which exercise the video device driver functions. Stress and cross product interaction are used to stress the video device drivers, by running combinations of existing industry applications (such as those used in FVT), product applets, system test developed applets, and SVT test cases, which will produce a multi-threaded multi-tasking use of the video device drivers.

Knowledge of several unique and a few odd terms are necessary for a proper understanding of the SVT process. These include:

Preconditioner Any other process run prior to a test to provide a certain stress or otherwise condition to the system environment.

Script A textual input script or 'program' for a test tool.

Scenario A type of test - several 'variations' on the scenario may exist (i .e., running different preconditioners).

Testcase For SVT, a test case consists of a specific variation on a specific scenario run on a specific Device Under Test (DUT).

Variation A slightly different version of a scenario. Typically, each scenario will have several variations, each running different preconditioners.
