传统的覆盖率度量的一个已知问题是,它们不评估Oracle质量,也就是说,计算结果是否实际上与预期进行了检查。在本文中,我们引入了检查覆盖的概念,即实际影响预言机的覆盖语句的动态切片。我们在七个开源项目上的实验表明,检查覆盖率是Oracle质量的可靠指标,甚至比突变测试更敏感。版权所有© 2013约翰威利父子有限公司.
A known problem of traditional coverage metrics is that they do not assessoracle quality—that is, whether the computation result is actually checked against expectations. In this paper, we introduce the concept ofchecked coverage—the dynamic slice of covered statements that actually influence an oracle. Our experiments on seven open‐source projects show that checked coverage is a sure indicator for oracle quality and even more sensitive than mutation testing. Copyright © 2013 John Wiley & Sons, Ltd.
