Public story · 2026-02-24 · source-backed
Martin Fowler's 25-year Agile anniversary workshop concluded TDD "produces dramatically better results from AI coding agents" because it prevents agents from writing tests that validate their own broken implementations. The Tweag Agentic Coding Handbook now documents TDD-as-specification-language: tests become executable requirements guiding AI toward exact behavior. Additional workshop findings: when AI accelerates coding, bottlenecks shift to architecture reviews and cross-team dependencies; security remains "dangerously behind."
This is now the 5th independent source confirming TDD convergence (Register, Latent Space, Willison, builder.io, Tweag). Three words to add to every agent prompt: "Use red/green TDD." Write failing tests first, then let the agent implement.
