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

Abstract

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, and the importance of establishing the reliability model containing rich test information to improve reliability is verified.

Description

technical field [0001] The invention belongs to the technical field of software testing, and in particular relates to a software fault detection method, system, storage medium, computer program and terminal. Background technique [0002] At present, software testing is an important means to continuously improve software reliability. It has been widely used to quantitatively study the improvement of software reliability in the testing phase by using the software reliability growth model SRGM. To effectively measure and predict reliability, it is necessary to conduct research on the basis of establishing an accurate mathematical model. The software testing process is the unification of multiple complex random processes. The software reliability growth model SRGM (software reliability and growth model) assumes this process, removes several factors, establishes a mathematical model from fault detection to repair process, and obtains a certain t Accumulate the number of detected...
