Abstract

As fixing bugs is a large part of software development and maintenance, estimating the time to fix bugs -bug fixing time- is extremely useful when planning software projects. Therefore, in this study, we propose a way to estimate bug fixing time using bug reports. First, we classify previous bug reports with meta fields by applying a k-NN method. Next, we compute the similarity of the new bug and previous bugs by using data from bug reports. Finally, we estimate how long it will take to fix the new bug using the time it took to repair similar bugs. In this study, we perform experiments with open source software. The results of these experiments show that our approach effectively estimates the bug fixing time.

버그 정정 활동은 소프트웨어 개발과 유지보수 작업에서 많은 비중을 차지하므로, 버그 정정활동에 소요되는 시간을 미리 추정할 수 있다면 소프트웨어 프로젝트 작업 계획에 큰 도움이 될 것이다. 따라서 본 연구에서는 버그 리포트를 이용하여 버그 정정 시간을 추정하는 방법을 제안한다. 본 방법에서는 먼저, 버그 리포트가 제공하는 버그 메타 필드에 k-NN 방법을 적용하여 과거 버그 리포트들을 분류한다. 다음으로, 버그 리포트의 텍스트 정보를 활용하여 과거 버그와 새로운 버그 사이의 유사도를 계산하고, 유사한 버그의 정정 시간을 활용하여 새로운 버그의 정정 시간을 추정한다. 마지막으로, 오픈 소스 프로젝트에 본 방법을 적용한 실험을 통하여 효과적으로 버그 정정 시간을 추정한다는 것을 보인다.
