An Insight into Code Smell Detection Tool

A code smell isn’t a bug and it won’t help your system operate exceptionally. It might simply make it more difficult for software engineers to comprehend and maintain project source code, resulting in extra maintenance expenses. Researchers have provided a variety of techniques and tools for extracting code smells throughout the last 20 years. Therefore, there is a need for comprehensive research that summarizes and compares the large range of existing tools. We present a complete catalogue of all known code smell detection tools in this paper. We found 112 tools as a result of our study, 52 of them available for download online. They also support a variety of programming languages including Java, JavaScript, C, C++, C#, Python, and others. We categorize different code smell detection tools in this study based on their type, availability, detection techniques, identified code smells, supported languages, and main features.
