VerChor: A Framework for Verifying Choreographies

International audienceChoreographies are contracts specifying interactions among a set of services from a global point of view. These contracts serve as reference for the further development steps of the distributed system. Therefore their specification and analysis is crucial to avoid issues (e.g., deadlock, requirement violation, faulty contract, etc.) that may induce delays and additional costs if identified lately in the design and development process. In this paper, we propose first to describe choreographies using an intermediate format in order to support various choreography specification languages as input. Second, we propose a connection to a formal verification toolbox as back-end, which includes the generation of verification scripts for fully automating the aforementioned checks. This results in a generic, modular, and extensible framework for supporting the verification of choreographies
