Uma ferramenta de análise de robustez para a melhoria da qualidade de sistemas de software. 2013. 78f. Dissertação (Mestrado em Engenharia de Produção) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2013.https://repositorio.ufrn.br/jspui/handle/123456789/27152A software product is considered reliable if it can deliver its functions the way they were defined. Robustness is a sub-attribute of reliability and concerns the software's ability to respond specifically to external defects. The exception handling mechanisms should ensure the robustness of the systems. However, in practice it is difficult to achieve such a goal, either by misuse of existing models, either by deficiency of the models themselves. Moreover, it is clear that developers dealing exceptions properly end up having serious problems in productivity, while its neglect although more productive, tends to generate less reliable systems and subsequent rising cost of post-production. Some real disasters were directly related to the neglect of exception handling, for example: the case of the European Ariane 5 rocket that self-destructed soon after launch, and the radar system Brazilian X-4000 which was nominated as one of the causes the crash of Gol Flight 1907 in 2006. In this context, this work presents a static analysis tool exceptional flow eFlowMining, focused on improving the robustness of applications. NET. It allows the developer: view metrics collected on the exceptional behavior; analyze the exceptional flow via a graphical representation as a tree; identify possible bugs between different versions of the same application, and quickly locate the types of exceptions thrown and their their handlers. All information collected is stored in databases to enable searches and comparisons of the analyzes. The evaluation tool was divided into two phases. The first aimed to show the consistency and accuracy of the tool relative to the different programming languages supported by the platform. NET. The second assessed how the tool helped developers identify possible defects between different versions of the same software system.Sistemas de SoftwareQualidadeTratamento de Exceções.RobustezAnálise EstáticaPlataformaNETmasterThesisCNPQ::ENGENHARIAS::ENGENHARIA DE PRODUCAO
