A Safety Test Case Generation Approach for Airborne Software Based on General Failure Modes
Yunfeng Lu, Chao Li, Yang Liu · 2019
The safety of airborne software has an important impact on the flight safety of aircraft, and software safety testing is an important means to improve software safety. Previous studies have proposed a variety of software safety testing methods, but in the case of coarse software safety requirements, it cannot generate sufficient test cases. Moreover, the quality of software safety test cases relies heavily on the experience and capabilities of the software testers. This paper proposes a safety test case generation approach for airborne software based on general failure modes, which extracts general failure modes and suggests key test points. Even if the software safety requirements are incomplete, it can assist software testers to generate safety test cases and improve the sufficiency of software safety testing. Besides, using this approach can also improve the efficiency of generating software safety test cases. The application case study proved the approach is usable and valid.
