Evolution analysis of software quality metrics in an open-source java project: A case study on TestNG
Software quality is critical in modern software engineering, especially in large and evolving codebases. This study analyzes the evolution of software quality metrics in five successive versions of the open-source Java testing framework TestNG. Using the static analysis tool Understand, eleven key object-oriented metrics, including cyclomatic complexity, class coupling, and lines of code, were extracted for each version. Statistical and visual analyses reveal structural trends over time. The re…
