Comparison with a golden run is commonly used as an oracle in robustness testing based on fault injection. However, traditional comparison algorithms present, among other limitations, requires the system under test to present, for the same workload, the same behavior, either in presence or in absence of faults. We present an approach that uses a pairwise sequence alignment algorithm in the comparison allowing faulty traces to have some regions of dissimilarity regarding the golden run. This is possible because the algorithm is based on inexact matching and aggregates to the search semantic aspects based on SUT specification. The approach can obtain the degree of similarity with the golden run, and visually presents similarities and differences, which helps in diagnosing. This paper illustrates the application of the approach on traces collected during robustness testing of the Wireless Transaction Protocol (WTP).
Samsung R&D Institute Brazil (SRBR) é um dos institutos de pesquisa da Samsung no mundo. O time do SRBR vem trabalhando em colaboração com a matriz da Samsung (localizada na Coréia do Sul) e instituições parceiras do Brasil para produzir software para produtos Samsung. O SRBR incorporou testes de aceitação em seu processo de desenvolvimento de software para assegurar que todo software produzido por parceiros do SRBR esteja de acordo com o processo corporativo da Samsung e requisitos propostos pelo SRBR. Este relato de experiência apresenta o resultado de testes de aceitação em três projetos desenvolvidos em Manaus com participação de parceiros.
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.
