Refactoring patterns study in code clones during software evolution
Jaweria Kanwal, Katsuro Inoue, Onaiza Maqbool · 2017
To investigate how code clones are handled by developers when they perform refactorings during software releases, we performed a longitudinal study on different versions of five Java systems. Our results show that a small proportion of code clones are refactored during the releases and code clones of same clone class are refactored consistently.
