Abstract:
An automatic test method and device for fault diagnosis. The method comprises: determining an object to be tested and a fault type to be tested (101, 201); executing a test case corresponding to the object to be tested and the fault type to be tested, the test case being data generated according to a preconfigured test specification and capable of being executed by the object to be tested (102, 202); when it is determined that a fault corresponding to the fault type to be tested is triggered, recording a first fault code and first freeze frame data on a bus (103, 203); requesting, after the fault ends, a second fault code and second freeze frame data from the object to be tested (104, 204); and according to the first fault code and the second fault code, and the first freeze frame data and the second freeze frame data, determining whether a fault diagnosis function of the object to be tested is normal (105, 205). Therefore, an automatic testing of the fault diagnosis function can be realized without manual operation of a user, thus saving labor cost and improving test efficiency; furthermore, testing under various scenarios can be realized by simple environment configurations, thus improving test coverage.
