Evaluation of three specification-based testing criteria

This paper compares three specification-based testing criteria using Mathur and Wong's PROBSUBSUMES measure. The three criteria are specification-mutation coverage, full predicate coverage, and transition-pair coverage A novel aspect of the work is that each criterion is encoded in a model checker and the model checker is used first to generate test sets for each criterion and then to evaluate test sets against alternate criteria. Significantly the use of the model checker for generation of test sets eliminates human bias from this phase of the experiment. The strengths and weaknesses of the criteria are discussed.
