Proportional sampling strategy: a compendium and some insights

There have been numerous studies on the effectiveness of partition and rand om testing. In particular, the proportional sampling (PS) strategy has been proved, under certain conditions, to be the only form of partition testing that outperforms random testing regardless of where the failure-causing in puts are. This paper provides an integrated synthesis and overview of our r ecent studies on the PS strategy and its related work, Through this synthes is, we offer a perspective that properly interprets the results obtained so far, and present some of the interesting issues involved and new insights obtained during the course of this research.
