代码坏味研究综述

Survey on Code Smells

代码坏味(code smells)是低质量的急需重构的代码片段.代码坏味是软件工程领域的一个研究热点,并且相关研究方向众多、时间跨度大、研究成果丰富.为梳理相关研究思路和研究成果、分析研究热点并预判未来研究方向,对1990年至2020年6月间发表的代码坏味相关的339篇论文进行了系统地分析和归类,对代码坏味的发展趋势进行了分析与统计,量化揭示了相关研究的主流与热点.揭示了学术界关注的关键代码坏味,并研究了工业界与学术界的关注点的差异及其影响.

Code smells are low-quality code snippets that are in urgent need of refactoring.Code smell is a research hotspot in software engineering,with many related research topics,large time span,and rich research results.To sort out the relevant research approach and results,analyze the research hotspots,and predict the future research directions,this study systematically analyzes and classifies 339 papers related to code smell published from 1990 to June 2020.The development trend of code smells is analyzed and counted,the mainstream and hot spots of related research are quantitatively revealed,the key code smells concerned by the academia are identified,and also the differences of concerns between industry and academia are studied.
