Abstract: The credibility of mutation score is questioned because it is computed without regard to fault detection difficulty level. A fault-detecting capacity evaluation model about test suit considering fault detection difficulty level is suggested. Based on logistic regression, the quantitative relation between the fault recognition probability and fault detection difficulty level is expressed. With the area under this relation curve, the mutation score is redefined. The new defined mutation score is not affected by fault detection difficulty level and avoid inaccuracy of classical mutation score because of the appearance of equivalent mutants.
