Adding tests for ai generated code is non-negotiable. Learn tdd with vibe coding, how to have ai write unit tests, build regression tests for agents, and practice test driven ai development.

Workflow

1. Write acceptance cases
2. Generate implementation
3. Generate tests
4. Run
5. Fix
6. Lock regressions

TDD with vibe coding

Start from failing tests when behavior is clear. Agents perform better with executable truth.

AI write unit tests — prompts

Specify public API, edge cases, and forbidden brittle assertions.

Regression tests for agents

Every agent bug becomes a permanent test.

Final takeaway

Tests are how you keep agent speed without quality collapse.

At The Vibe Developers, green builds beat green demos.
