Service oriented computing is based on a typical combination of features such as very late binding, run-time integration of software elements owned and managed by third parties, run-time changes. These characteristics generally make difficult both static and dynamic verification capabilities of service-centric systems. In this domain verification and testing research communities have to face new issues and revise existing solutions; possibly profiting of the new opportunities that the new paradigm makes available. In this paper, focusing on service orchestrations, we propose an approach to automatic test case generation aiming in particular at checking the behaviour of services participating in a given orchestration. The approach exploits the availability of a runnable model (the BPEL specification) and uses model checking techniques to derive test cases suitable to detect possible integration problems. The approach has been implemented in a plug-in for the Eclipse platform already released for public usage. In this way BPEL developers can easily derive, using a single environment, test suites for each participant service they would like to compose.
