Applying Code Quality Detection in Online Programming Judge

Abstract

This article presents an enhanced programming online judge system that not only evaluates the correctness of the submitted program code but also detects its code quality. Both results of the correctness and quality detection are responded through web once the compilation, the execution and the quality detection of the submitted source code have been finished. We take advantage of SonarQube to provide code quality detection in our online judge system named neoESPA. Comparing with other online judges, our proposed work has significant advantages in helping both the instructor to discover the weaknesses in the lecture and the students to locate their mistakes efficiently.
