On the relationship between partition and random testing
Tsong Yueh Chen, Y.T. Yu · IEEE Transactions on Software Engineering · 1994
Weyuker and Jeng (ibid., vol. SE-17, pp. 703-711, July 1991) have investigated the conditions that affect the performance of partition testing and have compared analytically the fault-detecting ability of partition testing and random testing. This paper extends and generalizes some of their results. We give more general ways of characterizing the worst case for partition testing, along with a precise characterization of when this worst case is as good as random testing. We also find that partition testing is guaranteed to perform at least as well as random testing so long as the number of test cases selected is in proportion to the size of the subdomains.>
