Abstract ETCS on-board equipment is a typical safety-critical system, its reliability plays a vital role in the safe driving of trains. ETCS on-board equipment has huge functions, complicated structure, a large number of test cases and difficult implementation. Introducing automated testing into on-board equipment testing is a problem that needs to be solved urgently. Based on the interface and functional characteristics of ETCS on-board equipment, this paper adds the design of test management unit, the division of test engine and the separation of test scripts based on the existing test environment, and develops a set of simple and efficient ETCS on-board equipment dedicated automation test environment. The application shows that this set of test environment realizes the automatic test of all test sequences of ETCS on-board equipment, which can significantly improve the test efficiency, reduce the tester’s work intensity, and improve the test accuracy.
