This study examines how the effectiveness of unit tests generated by LLM-powered coding agents varies with code maintainability, measured by CodeScene's CodeHealth. Results indicate that AI tools perform better on high-quality, easy-to-maintain source code.

AI-assisted summary based on the listed source.

Coding agents powered by Large Language Models (LLMs) are now prominent in software engineering. Previous work has shown that AI tools perform better on high-quality source code that is easy to maintain. In this study, we investigate how the effectiveness of LLM-generated unit tests varies across maintainability...

Understanding the relationship between code quality and AI-generated tests can guide developers in improving code maintainability to leverage AI tools more effectively. This insight helps optimize the use of LLMs in software engineering workflows.
