摘　　要：目前针对列车运行监控装置(LKJ)的测试普遍采用化整为零的方式,以功能特征作为划分依据,对LKJ业务功能采用等价类划分或边界值分析进行单项测试。但LKJ在运用过程中存在多个业务场景交织的情况,当被测试的业务功能与其他业务功能耦合时,测试结果可能会与预期结果不一致。为此根据LKJ业务功能的时间与空间特性,提出一种基于N维复杂业务场景的测试方法。将LKJ业务功能分解得到LKJ单位功能,依据时间法或空间法将LKJ单位功能构建形成复杂场景。通过对LKJ业务功能复杂场景进行测试,更加全面地覆盖LKJ实际运营场景,提高设计开发过程测试的异常发现率,进一步降低LKJ在实际运用中出现非预期行为的概率。At present,the method of“dividing into elements”is generally adopted for the LKJ test:the functional characteristics are used as the basis for division,and the equivalence class partitioning or boundary value analysis is used to conduct a single test on the LKJ business function.However,as multiple business scenes will be intertwined during LKJ applications,the test results may be inconsistent with the expected results when the tested business functions are coupled with other business functions.Therefore,according to the temporal and spatial characteristics of LKJ business functions,an LKJ test method for constructing complex scenes based on N-dimensional is proposed.The LKJ business function is decomposed to obtain the unit function of LKJ which is constructed into a complex scene based on the time method or space method.Through the test of complex scenes of LKJ's business functions,the actual operation scenes of the LKJ are covered more comprehensively,improving the anomaly detection rate of design and development process testing and further reducing the probability of unexpected behaviors in LKJ's actual application.
