Bad smells are sub-optimal code structures that may represent problems needing attention.
We conduct an extensive literature review on bad smells relying on a large body of …

Context Reusing a design pattern is not always in the favor of developers. Thus, the code
starts smelling. The presence of “Code Smells” leads to more difficulties for the developers …

Refactoring detection is crucial for a variety of applications and tasks:(i) empirical studies
about code evolution,(ii) tools for library API migration,(iii) code reviews and change …

Refactoring detection algorithms have been crucial to a variety of applications:(i) empirical
studies about the evolution of code, tests, and faults,(ii) tools for library API migration,(iii) …

Context Smells in software systems impair software quality and make them hard to maintain
and evolve. The software engineering community has explored various dimensions …

The metaphor of technical debt was introduced to express the trade off between productivity
and quality, ie, when developers take shortcuts or perform quick hacks. More recently, our …

Code smells are symptoms of poor design and implementation choices. Previous studies
empirically assessed the impact of smells on code quality and clearly indicate their negative …

Code smells can be used to capture symptoms of code decay and potential maintenance
problems that can be avoided by applying the right refactoring. They can be seen as a …

Previous studies have shown the negative effects that low-quality code can have on
maintainability proxies, such as code change-and defect-proneness. One of the symptoms of …

Context Code smells are patterns in source code associated with an increased defect rate
and a higher maintenance effort than usual, but without a clear definition. Code smells are …
