Theoretical comparison of testing methods

Comparison of software testing methods is meaningful only if sound theory relates the properties compared to actual software quality. Existing comparisons typically use anecdotal foundations with no necessary relationship to quality, comparing methods on the basis of technical terms the methods themselves define. In the most seriously flawed work, one method whose efficacy is unknown is used as a standard for judging other methods! Random testing, as a method that can be related to quality (in both the conventional sense of statistical reliability, and the more stringent sense of software assurance), offers the opportunity for valid comparison.
