Research on a Software Fault Injection Model Based on Program Mutation

This paper researches the classification of fault injection technology, software fault injection and program-oriented mutation testing technology. On the basis of existing work, this paper puts forward a software fault injection model based on program mutation with the idea of fault injection, analyses the key technology of the model, and compares with other fault injection techniques. The model in this paper can be used to evaluate the adequacy of the test suite by using mutation testing, which provides a basis to improve the fault test suite. To some extent, applying this model can improve the ability of fault detection and provide some useful reference data for software reliability evaluation.
