Acceptance trials for a real time system
National Data Processing Service, Harmondsworth, Middlesex, UK
Functional acceptance trials had to be carried out on 250,000 lines of code in just two weeks on the LACES system at London Airport. Complicated user interactions precluded parallel running and absolute confidence in these trials was therefore essential. This paper describes the general principles behind the approach which was successfully developed for the purpose, based partly on emulating the Post Office technique for testing Automatic Telephone Exchanges.
