摘要
阐述了软件可靠性测试及其加速方法,并对现有的加速方法进行深入分析和总结,将现有方法分为基于改变剖面概率的方法、基于灰盒分析的方法和基于多种测试信息的方法3类并进行比较。在此基础上,分别从提高输入强度、化简软件结构和输入以及提高置信水平3个方面进行了可靠性测试加速方法机理分析,得出基于改变剖面概率的方法只能起到部分加速作用,而其它两类方法可以起到整体加速作用,最后讨论了软件可靠性测试加速方法未来有前景的研究方向。
The concept and characteristics of software reliability testing are introduced and analyzed.Prevalent software reliability accelerated testing methods can be broadly classified into three categories,namely,changing probability based,grey box analysis based and multiple info based.The research achievements and development in software reliability accelerated testing method are mainly analyzed,summarized and discussed.And the conclusions are that the changing probability based approach can be accelerated partly and the others can be accelerated completely.Based on this the principle of software reliability accelerated testing methods is studied,and the research direction in the future is proposed.
