Software fault detection method and system, storage medium, computer program and terminal

The invention belongs to the technical field of software testing, and discloses a software fault detection method and system, a storage medium, a computer program, a terminal and a unified fault detection and repair framework model. Fault detection is considered under the fault detection rate, and an imperfect debugging framework model is repaired and introduced; and five forms are set for the obtained two unified imperfect troubleshooting framework models under initial conditions, and then five condition cumulative fault detection functions are obtained respectively. A unified fault detectionmodel is provided, a single differential equation capable of being used for implementing FDR research is established, then a test model covering fault detection, repair and introduction is established, and a differential equation set capable of implementing FDR research is established. Through the performance of the two types of reliability models under FDR support, it is possible to distinguishdifferent FDR performance,
