Abstract

The relationship between software testing and reliability is discussed. Two kinds of reliability models, reliability-growth models, which are applied during debugging, and reliability models, which are applied after debugging, are described. Several reasons for the failure of conventional reliability theory in software engineering are presented. It is argued that until random testing of a million points becomes practical, testing for quality is only a poor competitor for other heuristic defect-detection methods.
