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
