Test-Driven Development
A software development methodology that requires developers to write failing test cases before writing the implementation code that makes those tests pass. This approach drives sound interface design and code quality by anchoring development around predefined test specifications.

To remedy the problem of AI-generated code lacking boundary condition handling, one needs to explicitly state exception requirements in the prompt, or introduce test-driven development (TDD) to have the AI write tests first and then the implementation, thereby making boundary conditions explicit.
Tests should be based on specification rather than implementation.
TDD fails for AI agents because even when tests are written first, the agent still uses the same language model within the same context window to understand the requirements, making it impossible to separate the cognitive sources of the question-setter and the question-answerer.
The design philosophy behind Devin's self-testing capability is consistent with the test-driven development (TDD) concept in software engineering, with the executing subject shifting from human to AI.
Matt believes a good codebase is one that is easy to test, and that test-driven development is a key skill that forces LLMs to slow down.
