This paper proposes novel techniques for the extraction of structural information from the source code of Java concurrent programs for their coverage testing. Such techniques differ from others because they consider synchronization flow among processes/threads, distinct paradigms of communication/synchronization, method calls and pointer manipulation. The structural information gathered from the source code is kept in a test model based on a Parallel Control Flow Graph (PCFG) and helps the generation of an instrumented source code, used for a future generation of trace files and to replay the concurrent execution. The results show the techniques can generate both an instrumented code and a PCFG for Java concurrent programs effectively, extracting static and runtime information required for structural testing.
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.
