A methodology for designing and executing ISDN feature tests, usingautomated test systems

摘要

The CSATS (circuit switch automated test system) architecture, themethodology used by CSATS to develop ISDN tests, and the challenges inproviding thorough test coverage are discussed. A key procedure(functional decomposition) used in the test script planning stage isdiscussed using two ISDN features as examples. Three methodologies(defaults with user control, guided walk, and orthogonal arrays) arediscussed, and their roles in choosing test cases and improving testingefficiency are explained
