Mutation testing (mutation analysis) is a structural software testing method which involves modifying the program in small ways. Mutation analysis has been largely used in white-box testing, but only a few tentative attempts to use this idea in black-box testing have been reported in the literature. In this paper, we provide a formal way of generating mutants for systems specified by context- free grammars. Furthermore, the paper shows how the proposed method can be used to construct mutants for a P system specification, thus making a significant progress in the area of P system testingapplication/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccesshttps://idus.us.es/xmlui/handle/11441/38875
