Testing AI-Generated Code: How to Actually Know If It Works

Generative AI
I shipped a bug to production in January that embarrassed me. Not a subtle bug. A bug where a rate limiting function the AI wrote silently swallowed errors and returned true for every request, which meant our rate limiter was not actually rate limiting anything. The function looked fine on a visual scan. The TypeScript compiled. My quick test of the happy path worked. I merged it. The rate limiter failure showed up a week later when someone ran 4,000 requests in two minutes and our costs spiked.
