A Participant Testing Strategy for Service Orchestrations

Service Oriented Computing is an emerging discipline that promotes and make easier inter-organization integration of software systems. In such a context interoperability issues are considered a primary threat for a correct integration. Testing can be a fruitful approach helping to reduce interoperability mismatches. In this paper, considering the case of services to be integrated within an orchestration, we propose a testing derivation strategy based on a counter-example based technique. The state explosion phenomenon, caused by the presence of complex data sets, is handled by applying Genetic Algorithm strategies.
