After several months experimenting with AI-assisted TDD, I’ve refined a workflow that allows me to combine the strict discipline of traditional TDD with the capabilities of AI assistants. It’s not about accelerating the process at any cost, but about maintaining quality and control while the agent handles the more mechanical tasks. The challenge of staying on track One of the main problems when working with AI assistants in TDD is maintaining process discipline. The temptation is real: letting the agent generate both tests and implementation in one go seems efficient. But by doing so, we lose the fundamental benefits of TDD. We lose the emergent design guided by tests, the minimal necessary implementation, and that confidence the process gives you when you need to refactor. ...

The practice of AI-assisted TDD (Test-Driven Development supported by artificial intelligence) combines the core principles of TDD with the capabilities of large language models (LLMs). In this approach, the developer collaborates with an AI assistant during the development cycle, leveraging its ability to generate code and maintain the iterative rhythm characteristic of TDD. One of the main challenges when working with AI assistants is preserving consistency and direction throughout the process. In this context, it becomes especially relevant to revisit a concept introduced by Kent Beck more than two decades ago: the test list as a guide for development. ...
