“…In a distributed computing environment, research efforts have developed systematic ways to identify faults at design time to design fault management mechanisms. In (Carreira and Silva 1998), the motivation of fault injection in software systems is discussed, showing how faults are included in the code and the system reaction is studied, in order to identify coding errors or test unusual workloads or operational contexts. The first requirement of a fault tolerant mechanism is the ability to detect faults and the effects of faults, that is, failures.…”

Web service composition can be adopted to\ud develop information systems through integration of services\ud to obtain complex composed services. While interfaces of\ud services are known at composition time, the quality of a\ud composed service may depend on the ability of its\ud component services to react to unforeseen situations, such\ud as data quality problems and service coordination problems.\ud In this work, we propose an approach to analyze the quality\ud of composed services using fault injection techniques, by\ud inspecting the reaction of a composed process to injected\ud faults; the aim is to assess the process quality in terms of\ud fault monitoring and, more generally, fault tolerance\ud capabilities. The component services are analyzed either\ud as black-boxes, when only input and output messages are\ud considered or as white-boxes, when data sources used by\ud services are considered. A test bed is illustrated on a\ud selected example, and results of extensive testing are\ud discussed and framed into a process analysis methodology

“…Injeção de falhas é uma técnica experimental de validação. Falhas são introduzidas artificialmente no ambiente de execução de um sistema de forma a analisar o comportamento da aplicação, verificando se está de acordo com suas especificações [Carreira and Silva 1998]. Esta técnica permite introduzir artificialmente falhas de hardware, de software ou de interface entre sistemas.…”

Injeção de falhas é uma técnica experimental eficiente e de baixo custo para o teste dos mecanismos de tolerância a falhas de um sistema alvo. Uma extensão para o Perfil UML 2.0 de Testes (U2TP), usado para a modelagem de artefatos de teste, permite a descrição de artefatos necessários para injeção de falhas. Possibilita também a automação de parte do processo, como a criação de cargas de falha a partir de modelos UML. Este artigo apresenta as vantagens desta extensão. Como prova de conceito, apresenta também a geração de cargas de falha para injetores usados no teste de sistemas baseados em troca de mensagens. Diferentes artefatos podem ser gerados a partir de um mesmo modelo UML, tornando o processo de teste por injeção de falhas mais flexível, documentável e reusável.
