Abstract

In this work we propose a path-oriented test generationprocedure called POTENT to generate high quality tests fortransition faults. Both weak non-robust and strong non-robusttests can be generated by POTENT. We classify transition faulttests into six types according to their activation and propagationmethods. The basic idea of POTENT is to test a transition faultalong a longest testable path passing through the fault site. Fortransition faults that are activated or propagated through multi-paths,heuristics are proposed to maximize the propagationdelay of the target fault. We also propose an efficient method toevaluate the quality of a given transition fault test set.Experimental results show that POTENT generates higherquality transition fault test sets than the conventional testgeneration method.
