Mutation based testing of Web Services

Web services (WS) have been largely used in the development of Web applications. Because of this and due to their importance and inherent characteristics, there is a crescent demand for WS testing techniques and tools. Different testing approaches have been proposed, however most of them do not offer a criterion to be used to evaluate the generated test data. To allow this, the present work explores mutation operators, specific for WSDL documents. The idea is to consider semantic aspects of those documents and to reveal different kind of faults. A supporting tool is also described and evaluation results of a study case are discussed, which allow comparison with other approaches.
