Agents Should Do TDD: For the Same Reason You Should Have

April 26, 2026 · 15 min read

TDD's value was never that a human ran the loop. The value was the loop itself: a constrained search procedure that converges on code that is correct, named for intent, and shaped to change. Strip the human out and the discipline still works for the same reasons.

The Bar for TDD Just Moved

April 14, 2026 · 9 min read

Agentic coding changes what 'good tests' means. The new floor is scenario-rich, builder-driven, domain-typed tests authored by product-thinking developers, because that's the artifact agents actually compose against.

BDD Was a Coordination Tax. AI Just Repriced It

April 7, 2026 · 11 min read

Gherkin was never really a test format. It was a coordination protocol between specialized roles. In the AI era, where roles compress and translation is cheap, the protocol becomes friction instead of leverage.

TDD Already Does BDD, Without the Gherkin

March 24, 2026 · 8 min read

BDD wasn't a discovery. It was a rebrand of what disciplined TDD was already doing. Test data builders, factory hierarchies, and mock-driven collaboration tests are the scenarios, and they evolve alongside the code instead of rotting beside it.

Katas Are Rehearsal, Not Performance

February 28, 2026 · 3 min read

You don't practice TDD on production code. You practice on katas and bring the muscle memory to production. The gap between knowing TDD and doing TDD is reps.

Your Test Suite Is Your API for Agents

February 15, 2026 · 3 min read

Documentation lies. Wikis rot. READMEs drift. Your test suite is the only specification that stays current, and it's the interface AI agents actually use.

AI Agents Need Test Suites, Not Code Reviewers

February 1, 2026 · 3 min read

Autonomous AI agents can plan, implement, and deliver code. But without automated verification, you're just producing unreviewed changes faster. TDD provides the feedback loop agents actually need.

TDD Is Scaffolding for AI, Not a Speed Bump

January 1, 2026 · 3 min read

AI generates code fast. But speed without verification is just higher-velocity guessing. TDD provides the specification layer that makes AI-generated code trustworthy.
