Refactoring is a process of changing the source code of a program so that the internal structure of the code improves without changing the external behavior of the program. It cleans the software by eliminating bad smells from the software and makes the software easy to understand, and maintain, and reduces its maintenance cost. The presence of bad smells indicates some problematic code in the software that needs to be eliminated. Tools are available to eliminate such codes from the software. In the current work, refactoring is performed on six open-source software to eliminate bad smells and then the analysis is performed to know the impact of refactoring on the quality of software in terms of external and internal quality attributes. The complexity of the software has been calculated and compared with the initial complexity before applying refactoring. Similarly, quality attributes are calculated before performing any type of refactoring, and the same are calculated again after applying suitable refactoring based on the type of bad smell. Last, a comparison of changes has been done to know the refactoring impact on the quality of open-source software.

Refactoring, bad smells, software quality attributes, open source software.
