An exploratory study of bug-introducing changes: what happens when bugs are introduced in open source software?
share
Context: Many studies consider the relation between individual aspects and bug-introduction, e.g., software testing and code review. Due to the design of the studies the results are usually only about correlations as interactions or interventions are not considered. Objective: Within this study, we want to narrow this gap and provide a broad empirical view on aspects of software development and their relation to bug-introducing changes. Method: We consider the bugs, the type of work when the bug was introduced, aspects of the build process, code review, software tests, and any other discussion related to the bug that we can identify. We use a qualitative approach that first describes variables of the development process and then groups the variables based on their relations. From these groups, we can induce how their (pair-wise) interactions affect bug-introducing changes.
