Abstract: In access test of Beijing subway equipment and systems, it is necessary for these equipment and systems to test whether they can handle the abnormal data in a way which is defined in Beijing rail transit AFC system?design and implementation specification. Currently the test method has not high degree of automation, and testers cannot complete the test work well unless they are familiar with AFC. To solve this problem, a tool for testing abnormal connections is designed and implemented by analyzing the test work and concluding the kinds of test data and test flow. The tool can produce test data and perform test cases automatically. It is proved to be effective through actual test.

Key words: abnormal connections, Automatic Fare Collection（AFC）, testing, automation

摘要： 北京地铁车站设备和系统对异常数据的处理是否符合北京轨道交通AFC系统设计及实施规范要求，是地铁新线接入测试的必须环节。针对当前测试方法自动化程度不高，测试人员需要对AFC系统有详细了解才能很好地完成异常数据处理测试的问题，通过分析测试工作的内容，归纳测试数据与测试流程的种类，设计实现了具有自动生成测试数据、自动执行测试用例功能的异常连接测试工具；通过实际测试验证了设计工具功能的有效性。
