Automatizing Software Cognitive Complexity Reduction

Software plays a central role in our life nowadays. We use it almost anywhere, at any time, and for everything: to browse the Internet, check emails, even access critical services such as health monitoring banking. Hence, its reliability general quality is critical. As software increases complexity, developers spend more time fixing bugs or making code work rather than designing writing new code. Thus, improving understandability maintainability would translate into an economic relief over total cost of project. Different cognitive complexity measures have been proposed quantify piece and, therefore, maintainability. However, metric provided by SonarSource integrated SonarCloud SonarQube quickly spreading industry due popularity these well-known static tools evaluating quality. Despite suggests keep method’s no greater 15, reducing challenging human programmer there are approaches assist on this task. model reduction method optimization problem where search space contains all sequences Extract Method refactoring opportunities. then propose novel approach that searches feasible extractions allowing apply them, automated way. This will allow make informed decisions while their evaluated 10 open-source projects was able fix 78% 1,050 existing issues reported SonarQube. finally discuss limitations provide interesting findings guidelines developers.
