Analysis of incompatibilities between services: diagnosing all and identifying those which are fixable

National audienceThis text presents a tool, from its design to its implementation, which detects all incompatibilities between two service interfaces. Among all these incompatibilities, those which can be fixed by a mediator are identified. The tool focuses on behavioural dimension of service interfaces. Unlike prior work, the proposed solution does not simply check whether two services are incompatible or not, it rather provides detailed diagnosis, including the incompatibilities and for each one its location in the service interfaces. A measure of similarity between interfaces which considers outputs from the detection algorithm is proposed too. A visual report of the comparison analysis is also provided which pinpoints a set of incompatibilities that cause a behavioural interface not to simulate another one
