Configuring reference systems for certifying GKS implementations

The development of test packages for certifying GKS implementations is based on the falsification approach which provides a useful framework in the area of software validation. Although there are different test strategies, most of them follow the method of comparing test results against valid reference data. References used for certifying graphics systems are pictures or data which represent a picture at a particular interface. This paper outlines reference data used for testing GKS implementations at the device interface. Furthermore the process of configuring a GKS reference implementation and it's usage for certifying candidate GKS implementations is presented in detail. (AGD)
