Instant defect predicting method based on mixed effect removing

Abstract

The invention provides an instant defect predicting method based on mixed effect removing. The method comprises the following steps that 1, software change measurement is collected; 2, a mixed effect of the change measurement and change amount measurement is removed; 3, an unsupervised instant defect predicting model is built; 4, a change sequence is submitted to developers to be examined. According to the instant defect predicting method based on mixed effect removing, the problems that in an existing traditional instant defect predicting method, the data collecting difficulty is large, and the predicting capacity is insufficient are solved; not only can the instant defect predicting model be simply and effectively built, but also the examination cost can be significantly saved, therefore, limited resources are fully utilized, and the software product quality is better controlled and improved.

Description

technical field [0001] The invention belongs to the field of software engineering, especially the field of real-time software defect prediction, and in particular relates to a real-time defect prediction method based on the removal of mixed effects. Background technique [0002] With the continuous development of software technology, users have higher and higher requirements for software quality, and software developers are constantly looking for ways to improve software quality to meet user needs. A software defect is a problem, error, or hidden functional defect in computer software or programs that destroys normal operating capabilities, and is the failure or violation of a certain function that the system needs to achieve. Software defects accompany each process of the software development process. If the requirements are not fully clarified in the requirements analysis stage, many unnecessary software defects will be brought about. Failure to adopt excellent management ...
