A study on the Conformance Test for Protocols Written in Estelle

Estelle로 기술된 프로토콜의 적합성 검증에 관한 연구

The conformance test is a methodology which verifies whether the Implementation Under Test (IUT) conforms to its standard specification or not. In this paper, first, the Conformance Test System(CTS) is implemented in prototype including verification test type, black-box test strategy, conformance test class, remote test structure, and IUT which is described by the ISO Estelle among Formal Description Techniques. Second, through this prototype the proposed system is experimented. The prototype is composed of two modules. The first module is the Estelle-to-Pascal preprocessor which converts the Estelle program to the corresponding Pascal program because the experimental IUT was described using the unexecutable code form of Estelle before being tested by the TD(Test Driver). The TD, the second module, is based on the master-slave concept and plays important role is CTS. The TD acts as the master with the IUTd being the slave. The prototype system is implemented using Turbo-C, Turbo-Pascal and Turbo-Assembly.
