[0002] When using traditional SMT equipment to perform functional testing of SMT software, it is necessary to run the SMT software on the SMT equipment to perform software functional testing, which brings the following problems. On the one hand, the use of SMT equipment by testers will occupy the production tasks and plans scheduled by production personnel to use the SMT equipment. At the same time, there will also be the problem of coordinating time when sharing a device with other R&D personnel, which seriously affects the progress of testers in performing SMT software functional testing. The efficiency will be very low, which will bring great time costs. On the other hand, testers use traditional software testing methods to perform functional testing on SMT software, and some problems existing in the functional testing of SMT software cannot be automatically located and analyzed. The low testing efficiency affects the progress of the project.
