Problems solved by technology

However, current studies of this kind regard defect reports and source code files as "word packages". Although the semantics of the same word is often similar in defect reports and codes, only focusing on the degree of similarity between the two words will cause problems. The sequential information of the text is lost, resulting in the loss of part of the semantic information, which has a negative impact on the effect of defect localization

Abstract

The invention discloses a code method-level software defect positioning method, which belongs to the field of software maintenance, and comprises the following steps of: constructing and training a seq2seq model; constructing a defect positioning model based on the seq2seq model; constructing a training sample of the defect positioning model; training a defect positioning model by using the training sample; and predicting the defect method in the defect report by utilizing the trained defect positioning model. According to the method provided by the invention, historical data and a deep learning technology are combined to train a defect positioning model; according to the method, a seq2seq model is utilized to determine parameters of a code encoder in the defect positioning model, code method annotation is used as supervision information, the information amount is rich, the purpose of positioning software defects on the method level is well achieved, and the software defect repairing efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the field of software maintenance, in particular to a method for locating software defects at the code method level. Background technique [0002] During the development process, defects are unavoidable. In the traditional development process, when a software tester or software user discovers a defect, they will write a defect report in the defect tracking management system to inform the software development and maintenance personnel. The defect report records the reporting time, severity, abnormal program performance and details of how to reproduce the software defect. Software developers and maintainers need to manually determine the defect location based on the submitted defect report to fix the defect. In the actual defect repair process, repairers often spend a lot of time in the link of defect location. [0003] With the development of the software industry, software functions become more and more complex, and the numb...
