Abstract:Context: Software testing plays an important role in assuring the reliability of systems. Assessing the efficacy of testing remains challenging with few established test effectiveness metrics. Those metrics that have been used (e.g. coverage and mutation analysis) have been criticised for insufficiently differentiating between the faults detected by tests. Objective: We investigate how effective tests are at detecting different types of faults and whether some types of fault evade tests more than others. Our a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
