Using coverage as a test design technique works only when the testers are both designing poor tests and testing redundantly. 仅当测试员设计了的测试质量不高并且冗余地进行测试时，将测试度作为测试设计技巧才能起作用。
As a result, information will not be stored redundantly in several places at the same time and it will be possible to record available spare parts more quickly. 由于信息不会在同一时间冗余地存于几个地方，它将可能更快地记录可供备件。
