The invention discloses a universal automatic test system for rail transit signaling equipment, which has flexible interface and protocol configuration, automatic test and functions of equipment modeling and project management. The technical scheme is as follows: using keyword-based drivers, extensible, Easy-to-write test sequences are used as a way to edit test scripts, as the communication interface transmission mode require for supporting the signal equipment of the rail transit is interconnected with the test excitation source through the Ethernet, the coupling between the test excitationsource and the t excitation source is avoided, and the test interface mode can be added and configured according to the actual test interface requirement, so that the configuration of the communication protocol and the semantic definition and mapping are conveniently realized. Realize the closed-loop test management including system requirements, test requirements, requirements change management,test case management, test script framework import generation, test script editing, test plan generation, test plan execution, test process record, test report generation, automatic generation of round test plan according to defects, and so on, improve the degree of automation.
