CTCS－3级列控系统测试案例生成方法的研究

CTCS-3级列控系统是保障铁路行车安全、提高运输效率的重要设备，上道运用前必须在实验室和现场分别进行功能测试，建立CTCS-3级列控系统测试案例库对CTCS-3级列控系统的功能测试具有非常重要的意义。分析了系统需求规范、功能特征和测试案例之间的关系，研究了从系统需求规范和总体技术方案提取功能特征的方法和测试案例的生成方法。

Test Case Producing Manner of CTCS Level 3 Train Control System

CTCS level 3 train control system is one of the most important equipment to assure the safety of train operation and to enhance the efficiency of traffic. It is very significant to establish the test case aggregation for the function test of the system. In this paper, the authors analyzed the relationship among the system requirement specification, function features and the test case. Furthermore, the method to abstract function features from the system requirement specification and the general technical scheme was researched. The procedure to build the test cases is also described in this paper.
