Message Sequence Charts (MSCs) 已經被廣的泛用在軟體工程上的系統需球和測試標準,而在西元2005年時,MSCs被 Test and Testing control notation-version3(TTCN-3)採用做為它的圖形化表示法。我們已經研究和實做出一個易於使用的TTCN-3的圖形化表示法的環境的前端的部分,這個環境可以用來繪出MSCs 測試需求進而來產生出TTCN-3的測試語言。我們這篇論文描述這個前端部分所用的技術,這個前端部分接受TTCN-3的核心語言並將它轉換為圖形化的資訊,它也可以將圖形化的資訊轉化為TTCN-3的核心語言,因此,從圖形化的資訊來產生TTCN-3核心語言將會比文字模式下來的有效率。
Message Sequence Charts (MSCs) have been widely used in software engineering for system requirements and test specifications. Since 2005, MSCs also have been adopted as the test specification of Test and Testing Control Notations-version 3(TTCN-3). We have developed and implemented the front-end part of graphical user-friendly environment for the construction of MSCs test specifications. The paper reports the technology of the part of our whole environment. It accepts test specifications in TTCN-3 core-language and translates it into the graphical information. It also translates graphical information into TTCN-3 core language. Therefore, the writing and generating of TTCN-3 specifications can be efficient from graphical information.
