Predicting change in newly created files in a software product line project

Abstract

AbstractAt the beginning of the testing phase and before the deployment phase of a project's development cycle, we need to predict files with a high chance of change. Software products are always prone to change due to several reasons, including fixing errors or improvements. In this work, we used the Eclipse (releases from 2.0 to 3.5) to investigate how prediction models can perform when learning from a release and predicting in the subsequent one, which contains new files that models have not seen. We compared the performance of these models with models that are trained and tested on the same release. We found no differences between predicting the same release or subsequent release on two pre Europa releases. Predicting change in newly created files helps improve maintenance planning for software project managers and reduce cost. It will also help to enhance the quality of software by improving the practices of developers. This study used the Adaptive Boost classifier with the decision tree J48 algorithm and combined it with the re‐sampling method. We find this to be better than using a meta classifier alone or combine the re‐sampling with the standard classification. We compared our results with related works and found that our results are outperforming.
