Abstract

Web service composition can be adopted to integrate information systems as complex composed processes. While interfaces of services are known at composition time, the quality of the composed process may depend on the ability of component services to react to unforseen situations, such as data quality problems and coordination problems. In this work, we propose an approach to analyze the quality of composed services using fault injection techniques, by inspecting the reaction to injected faults in the composed process to assess its quality in terms of fault tolerance capabilities. The component services are analyzed either as black-boxes, when only input and output messages are considered or as white-boxes, when data sources used by the service are considered.
