A known problem of traditional coverage metrics is that they do not assess oracle qualitythat is, whether the computation result is actually checked against expectations. In this paper, we introduce the concept of checked coveragethe 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.
