Test Method of Flight Control Software based on Input Field Model

Flight control software is the nerve center of flight control system, which has high functional complexity and difficult test. In this paper, a test method based on input field model is proposed. The input space of flight control software is identified, and input domain modeling is carried out. According to the pairwise combination test coverage strategy, a heuristic test case generation algorithm with constraints is used to generate test cases so as to guide the test execution. The example shows that the characteristic modeling of flight control software input domain and the test based on the model can meet the requirements of the sufficiency and coverage of flight control software test, greatly improve the effectiveness of software testing and reduce the test cost.)
