Blasi, Arianna ; Stulova, Nataliia ; Gorla, Alessandra ; Nierstrasz, Oscar

In: Journal of systems and software, 2021, vol. 182, p. 14

Code comments are the primary means to document implementation and facilitate program comprehension. Thus, their quality should be a primary concern to improve program maintenance. While much effort has been dedicated to detecting bad smells, such as clones in code, little work has focused on comments. In this paper we present our solution to detect clones in comments that developers should...

MeMo : automatically identifying metamorphic relations in Javadoc comments for test automation

Blasi, Arianna ; Gorla, Alessandra ; Ernst, Michael D. ; Pezzè, Mauro ; Carzaniga, Antonio

In: Journal of systems and software, 2021, vol. 181, p. 13

Software testing depends on effective oracles. Implicit oracles, such as checks for program crashes, are widely applicable but narrow in scope. Oracles based on formal specifications can reveal applicationspecific failures, but specifications are expensive to obtain and maintain. Metamorphic oracles are somewhere in-between. They test equivalence among different procedures to detect semantic...
