For the embedded system, traditional development methods are time-consuming and system is not easy to maintain. Domain-specific modeling provides a solution for the problems. In this paper, we proposed development architecture for embedded control systems based on MIC. GME is used to construct meta-model and application model, model in-terpreter interprets model and stores model information in xml format document. The final cross-platform codes are automatically generated by different templates and xml format document. This development method can reduce time and cost in the lifecycle of system development.展开更多

However, little research has focused on testing web services. Based on the research of model checking techniques~ we propose a model checking based approach for testing web service composition which is described by using the web services choreography description language （WS-CDL）. According to worldwide web consortium （W3C） candidate recommendation, the WS-CDL specification provides a language for characterizing interactions between distinct web services using XML. Since the behaviors of web service composition are asynchronous, distributed, low-coupled and platform independent, we employ the guarded automata （GA） model for specifying the composition described in WS-CDL and using the simple promela interpreter （SPIN） model checker for detecting the collaborations of web services. Test cases can be transformed from counterexamples generated by SPIN using adequacy criteria. In this paper we apply the transition coverage criterion for generating counterex- amples. To illustrate our approach, we set ＂E-commerce service system＂ as an example for demonstrating how test cases can be generated using SPIN for compositions specified in WS-CDL.展开更多
