Dynamic Testing and Deployment of a Contract Monitoring Service

Internet and cloud based services involve electronic interactions that are normally regulated using service agreements (SA). Once an agreement between business partners is in place, a service can be monitored and/or enforced using an SA equivalent electronic contract. Because of the dynamic nature of such Internet and cloud based relationships, the rapidity at which electronic contracts are constructed, verified for correctness, tested, and deployed is an extremely important factor. This paper describes a model checker based framework for supporting the automated testing and deployment of electronic contracts. The central components of the framework are a contract monitoring service called the Contract Compliance Checker (CCC), the SPIN model checker, and EPROMELA, a language developed specifically for modelling electronic contracts. We describe how SPIN can be used to automatically generate execution sequences from an EPROMELA model of a contract, and how such sequences can then be used to test the correctness of the model equivalent electronic contract deployed to the CCC. © 2015 Newcastle University.
