It’s June now, and you know what that means — it’s AI month!
Just kidding. Every month is AI now.
So here’s the thing: if you’re vibe coding your way to rocket ship growth, you need TDD even more. AI-generated code is tricky to keep working right. Models tend to overwrite themselves, which makes it nearly impossible to know what your software actually does.
Tests written while practicing TDD are small, focused, and easy to understand. They act as a specification for the AI — and give you a way to verify that the output actually does what you intended.
Tests are the only way to have real confidence that even a small AI-built app does what you think it does.
And just to be clear — this applies to human-written code too!
