CopilotChat is an AI-powered tool designed to facilitate code generation through Test-Driven Development. The tool primarily operates in three steps. The first step includes defining test cases, where developers provide inputs, expected outputs, and an optional requirement description.

This feature allows for detailed planning of test-driven development processes and enables the setting of specific expectations for the code's performance.

The second step involves code generation. The LLM component of the tool is responsible for this, creating code based on the previously defined test cases and requirement descriptions.

This AI integration assists in accelerating the code development process while maintaining quality and efficiency. The third step consists of validation, where CopilotChat cross-verifies the generated code against the set test cases.

If a test case fails, the tool continuously interacts with the LLM to revise and refine the code until it successfully passes all the tests. This cyclical feedback loop ensures the final code is robust, accurate, and meets the predefined requirements.

The tool features a user-friendly interface and aims to improve developers' productivity and reduce both coding errors and the time it takes to test and troubleshoot codes.
