"Checked coverage: an indicator for oracle quality", David Schuler, Andreas Zeller, Softw. Test. Verif. Reliab. 2013
Abstract: A known problem of traditional coverage metrics is that they do not assess oracle quality—that is, whether
the computation result is actually checked against expectations. In this paper, we introduce the concept of
checked 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.
