For the integrated test items and flow, the solution featuring the automatic test method, the combination of different test items, and the electronic data record is proposed in this paper. Applying the above-mentioned solution, the test efficiency could be improved by more than 30% and the safety of test operation could be also exalted. At the same time, the solution has good universality and could provide reference for other similar integrated tests.展开更多
