PHIGS Validation Tests - Overview
The Programmer's Hierarchical Interactive Graphics System (PHIGS) is
a programming interface for the development of 3D graphics applications.
The NIST has developed an extensive set of test programs to determine whether
implementation of the PHIGS conform to the specifications of ANSI/ISO
standard 9592.1-1989. The tests are available for both the Fortran
and C binding of PHIGS. Version 2.1 (released April 1994) of the
PHIGS Validation Tests (PVT) adds test for interactive modelling and error
handling, and cleans up bugs and standard defects in version 2.0.
Conformance Testing
Conformance Testing a PHIGS product to determine if it faithfully implements
the requirements specified by the PHIGS standard. A well defined
set of metrics (e.g., a test suite) along with test procedures are used
to test a product's conformance. Vendors can use the metrics to debug their
products and ensure adherence to the standard and profile. The results
of conformance testing can reduce the risks and raise the consumer confidence
in the tested products.
