refactoring is the process of improving the design of existing code by changing its internal structure without affecting its external behavior. refactoring tends to improve software quality by improving design, improving readability and reducing 'bugs'. There are many different refactoring methods, each having a particular purpose and effect. Consequently, the effect of refactoring methods on software quality attributes may vary. Moreover, it is often unclear to software designers how to use refactoring methods to improve specific quality attributes. In this paper, we propose a classification of refactoring methods based on their measurable effect on software quality attributes. This, in turn, helps software designers choose appropriate refactoring methods that will improve the quality of their designs, based on the design objectives. It also enables them to predict the quality drift caused by using particular refactoring methods.

Empirical taxonomy of refactoring methods for aspect-oriented programming

引用

JOURNAL OF SOFTWARE-EVOLUTION AND PROCESS 2013年第1期25卷 1-25页

refactoring improves software quality by improving the design of existing code through changing its internal structure while preserving its behavior. Improving one quality attribute may impair other quality attributes. A number of refactoring methods were proposed specifically for aspect-oriented systems. However, there are no guidelines to help aspect-oriented software designer decide which refactoring methods to apply to optimize a software system with regard to certain design goals. In this paper, we propose a taxonomy/classification of refactoring methods for aspect-oriented programming based on their measurable effect on software quality attributes using six open-source aspect-oriented software systems.

The Impact of refactoring on Class and Architecture Stability

引用

JOURNAL OF RESEARCH AND PRACTICE IN INFORMATION TECHNOLOGY 2011年第4期43卷 269-284页

refactoring is used to improve the internal structure of the code without affecting its external behaviour. This is done by restructuring the components of the software, i.e. changing the internal structure within classes or changing the structure between classes. However, this may have an impact on class and architecture stability. In this paper we assess the impact of refactoring on class and architecture stability and then propose a classification for refactoring methods based on the impact of refactoring on class and architecture stability.
