TDD-GPT-Agent integrates OpenAI’s GPT-4 or GPT-3.5 models in a Python-based CLI to drive a fully automated test-driven development cycle. Given a developer’s function specification, it generates pytest test files, runs tests locally, analyzes failures, and produces implementation code to satisfy assertions. It repeats the cycle until all tests pass. Configurable via a YAML file, the agent supports prompt customization, session logging, Git integration, and can be embedded in CI/CD pipelines for continuous quality assurance. This AI-driven workflow accelerates development, improves coverage, and enforces reliable code.

Copilot Chat is an AI-powered conversational tool designed to assist developers in generating code using a test-driven development approach. It allows users to specify test cases that represent their coding intentions. Copilot Chat interacts with a large language model (LLM) to create, validate, and iteratively refine the code until it passes all test cases. This tool aims to simplify the coding process, reduce debugging time, and improve code quality by ensuring that generated code meets predefined test criteria.
