计算机网络中,描述一种协议并对其进行标准化并不能确保成功的通信,这是因为协议标准目前基本上是使用自然语言描述的,对协议的不同理解会导致不同的协议实现。一致性测试就是测试协议实现是否符合协议说明。TTCN是一致性测试中最常用的技术,本文介绍了目前在协议的一致性测试中最常的技术TTCN的发展,以及可以将测试用例可视化的技术MSC。
In computer networks, describing a protocol and standardizing it does not ensure successful communications because the protocol standard is currently largely described in natural language, and different interpretations of the protocol result in different protocols. Conformance testing is to test whether the protocol to achieve compliance with the agreement. TTCN is the most commonly used technique for conformance testing. This article presents the current development of TTCN, the technology most commonly used in protocol conformance testing, and a technology MSC that visualizes test cases.
