Check the README for package manager, auth, and platform requirements.
Try it in a small test task inside your agent workflow.
ChatUniTest uses AI to automatically create unit tests for your code. It first generates tests, then checks if they work, and fixes any errors. It also picks the most relevant parts of your code to help the AI make better tests.
ChatUniTest is an innovative framework designed to improve automated unit test generation. It utilizes an LLM-based approach enhanced with an 'adaptive focal context' mechanism to encompass valuable context in prompts and adheres to a 'Generation-Validation-Repair' mechanism to rectify errors in generated unit tests. The framework includes ChatUniTest Core, a common library implementing the core workflow, and the ChatUniTest Toolchain, a suite of seamlessly integrated tools that enhance its capabilities. It supports multiple research-backed implementations (e.g., for FSE, ICSE, ASE conferences) and can be used as a Maven plugin with different phase types. The tool aims to reduce the manual effort in writing unit tests and improve test coverage by leveraging large language models.
