Application of Test Method Based on State Transition Diagram in Flight Control Software

Abstract

Flight control software is the nerve center of flight control system, which has strong coupling of structure and function, which greatly increases the difficulty of test case design. In this paper, Test method based on state transition diagram (STD) is adopted. By analyzing the task scheduling of flight control software, the state transition diagram is designed according to the construction rules, and test paths are extracted according to the coverage rules, so as to guide the generation of test cases. An instance shows that the method can meet the requirements of flight control software test for sufficient coverage and improve the effectiveness of software test.
