Research on Simulation Technology Based on Fault Injection

The software test for actual combat needs to focus on verifying the interoperability capability, actual combat mission capability and system combat technical index of information system software. In the process of software testing, the fault model of software system can be studied from the aspects of system state fault, platform running fault and interface communication fault in actual combat environment. This article studies fault injection technology from two aspects: crosslinking interface and external environment. In the section of fault injection technology for crosslinking interfaces, the types of crosslinking interfaces and their interaction behaviour are summarized. The fault injection operators are designed. The fault injection testing process and a method for evaluating the adequacy of fault injection testing are proposed; In the external environment fault injection technology section, the methods of memory address acquisition, memory spatial analysis, register address acquisition and register spatial analysis are summarized. Also, the fault injection operators and the fault injection testing process are designed.
