[0003] 1. Only the main branch is analyzed, which is inconsistent with the company's common software development model
[0004] 2. There is no workload perception module, and the obtained results still need a lot of time to review, lacking operability

Embodiment

[0076] The time-wise cross-validation method was used for verification. The experimental results were compared from the five dimensions of recall, precision, f1-score, pci, and ifa, and the existing methods EALR and OneWay in the field of defect prediction. The results are shown in Tables 1 and 2. Show. In the test of six projects, the method in this paper finds about 15% more defects than the EALR method, and the recall is increased by about 47% on average. The detailed results are as follows:

Abstract

The invention discloses a workload-aware multi-branch software change level defect prediction method, which belongs to the field of change level code defect prediction. The method includes: extracting change meta information, data labeling, calculating the characteristics of each branch and multi-branch processing, training Apply a workload-aware model. This method adds a workload perception module to help developers find more defects in as little time as possible, and is operable.

Description

technical field [0001] The invention belongs to the field of change-level code defect prediction, and in particular relates to a workload-aware multi-branch software change-level defect prediction method. Background technique [0002] Take the Commit Guru tool as an example, (C.Rosen, R.Graw, E.Shihab.Commit Guru: Analytics and Risk prediction of software Commits.In Proceedings of the JointMeeting on Foundations of software Engineering 2015), this tool utilizes 14 Each measure (including the number of lines of code added or subtracted from files, developer experience, etc.) predicts defects in software changes through a logistic regression model. But it has the following disadvantages [0003] 1. Only the main branch is analyzed, which is inconsistent with the company's common software development model [0004] 2. Without a workload sensing module, the obtained results still need a lot of time to review and lack operability. [0005] These problems exist widely in other ...
