Abstract: The development of robust software systems relies heavily on effective unit testing to ensure code reliability and correctness. With the increasing complexity of modern applications, writing and maintaining unit tests can become a time-consuming task. This research explores the integration of GitHub Copilot, an AI-powered code completion tool, with the xUnit framework to optimize the unit test creation process. We investigate how GitHub Copilot can assist developers in generating, refining, and maintaining unit tests more efficiently, focusing on its impact on both productivity and code quality. Through a series of case studies and experiments, we assess Copilot's ability to suggest test cases, handle edge conditions, and generate mock setups for testing dependencies. The results indicate that AI assistance can significantly reduce the time spent writing tests, enhance test coverage, and support developers in addressing complex scenarios. Additionally, we discuss the limitations and challenges of using AI for test generation, particularly in ensuring test correctness and preventing over-reliance on AI-generated suggestions. This study contributes to the growing body of knowledge on AI-assisted software development, offering insights into the potential of combining machine learning tools with traditional testing frameworks like xUnit to create more efficient and scalable testing practices.
