Research on automatic test case generation method of flight control system based on UML state diagram

Abstract

In order to realize the automatic test of flight control system, the automatic generation method of flight control system test case is studied by using UML state diagram. Using UML extension mechanism, the real-time extension scheme of UML state diagram of flight control system is given. Aiming at the real-time performance of flight control system, the migration equivalence class is constructed by using the time domain equivalence partition method. After the test path is generated according to the corresponding test standard, the test case is generated automatically. Taking a simplified flight control system as an example, the feasibility and practicability of the method are verified by comparing the time of generating test cases with that of generating test cases manually.
