FIRMI: Um Injetor de Falhas para a Avaliação de Aplicações Distribuídas baseadas em RMI
Resumo
Aplicações distribuídas baseadas em RMI que precisem atender a requisitos de dependabilidade, devem demonstrar na fase de testes que operam corretamente mesmo na presença de falhas no subsistema de comunicação. Exceções geradas por RMI em resposta a falhas de comunicação devem ser capturadas pela aplicação e devidamente tratadas. Para provocar a ocorrência destas exceções e assim testar as estratégias de tratamento de erros da aplicação, falhas são injetadas durante a fase de testes e o comportamento do sistema sob o efeito destas falhas é observado. Este artigo apresenta um injetor de falhas para a avaliação de aplicações que usam o protocolo RMI. O artigo descreve as técnicas empregadas e demonstra as funcionalidades do injetor através da condução de um experimento.Referências
