Abstract. It mainly solves the test lag, is not visual and the test efficiency is low, and relies on the test design of testers, and it cannot guarantee the quality of the test cases and cannot guarantee the quality of the test. According to the steps to establish the software data flow graph model to verify the model, the artificial point of the test items for planning. Finally fill in the contents of the test items and according to the algorithm to generate the corresponding test case collection, save to the database for management.
