Um estudo comparativo entre Pull Requests com e sem refatoramentos através da análise de revisões de códigos.

Abstract

Over the years, code review has changed; before, a manual inspection was carried out (strict and synchronous), whereas nowadays, a more modern revision (asynchronous and less rigorous) is carried out. Currently, Git, through the Github platform, is the most popular version control system, favoring several discussions related to changes in source code. With the help of tools like RefactoringMiner, which provides detection of refactorings applied to source codes and, using a sample of repositories from the Apache project on Github, this work, through manual inspections of review comments, aims to understand and characterize the comments that induced refactorings in the PRs, in order to understand the characteristics and differences of the review comments in PRs with and without refactorings. Through the hypotheses raised, we tried to complement the understanding of the qualitative part of the review comments, previously addressed in a similar way in another research, which analyzed qualitative and quantitative data from PRs that induced refactorings and PRs that did not induce refactorings, with the intention of understanding better the differences between the two types of PRs, at the Pull Request level.
