TERTIARY STUDY ON LANDSCAPING THE REVIEW IN CODE SMELLS

Code smells are a sign of bad design and poor implementation decisions, which increases fault proneness and code complexity and reduces software system maintainability. Digital innovations are increasingly transforming the world in which businesses operate. The infusion of digital technologies into services, processes and goods has significant implications for how companies achieve and retain competitive advantages. The timely detection of code smells in a company's systems and software that operates an internet-based business, such as an e-commerce company that sells products and services over the internet, aids the company's team to build strategies to maintain and gain competitive advantages in the digital economy. However, there has been no specific landscaping research on code smells in recent studies that combine all of the disparate and classified information into a single paper. We performed a manual search process to collect various systematic literature reviews (SLRs) and mapping studies from 2015 to 2020. The aim was to cover and integrate as much information as possible based on code smells, such as previous years' methods and techniques, domains targeted thus far, and challenges faced between 2015 and 2020.
