Description

technical field [0001] The present invention relates to the fields of software testing and data mining, and more specifically, to a K-B-based software defect prediction method, device, electronic equipment and media. Background technique [0002] Since 1970, software defect prediction technology has begun to develop; as the scale of software systems becomes larger and the logic becomes more complex, software defects are bound to increase, affecting software quality. Because software defect prediction helps testers understand the status and Quality, helping to set delivery standards, so the prediction of software defects has also become important. [0003] At present, software defect prediction is divided into static and dynamic two prediction methods. With the number of software iterative updates and the increase of similar software, it has become a practical method to predict the number, type, and distribution of defects based on historical software development data and th...
