Mining the relationship between anti-patterns dependencies and fault-proneness

摘要

Anti-patterns describe poor solutions to design and implementation problems which are claimed to make object oriented systems hard to maintain. Anti-patterns indicate weaknesses in design that may slow down development or increase the risk of faults or failures in the future. Classes in anti-patterns have some dependencies, such as static relationships, that may propagate potential problems to other classes. To the best of our knowledge, the relationship between anti-patterns dependencies (with non anti-patterns classes) and faults has yet to be studied in details. This paper presents the results of an empirical study aimed at analysing anti-patterns dependencies in three open source software systems, namely ArgoUML, JFreeChart, and XerecesJ. We show that, in almost all releases of the three systems, classes having dependencies with anti-patterns are more fault-prone than others. We also report other observations about these dependencies such as their impact on fault prediction. Software organizations could make use of these knowledge about anti-patterns dependencies to better focus their testing and reviews activities toward the most risky classes, e.g., classes with fault-prone dependencies with anti-patterns.
