Why TDD works with AI coding agents: cheap guardrails and regression signals
randal_olson · x · 2026-10-02
Responding to "why do people do TDD with agents? seems incredibly inefficient," data scientist Randal Olson argues:
- AI coding agents work best with guardrails and a signal to measure improvement against
- Unit tests and linting are cheap signals that keep the agent's code sane
- Side benefit: you end up with a unit test suite that catches regressions
