One of the biggest misconceptions in AI development is believing that the system you tested is the same system users will experience.
It isn't.
During development, AI operates in a controlled environment.
Prompts are predictable.
Inputs are clean.
Workflows follow expected paths.
Production introduces something entirely different.
People.
Real users bring ambiguity, creativity, mistakes, and unexpected behavior.
That's why production AI often behaves differently than internal demos.
The challenge isn't just building a capable AI agent.
It's validating how that agent behaves when the environment becomes unpredictable.
Behavioral testing exists to reduce the gap between the AI you build and the AI your users experience.
That's why we're building Crucible.
Helping engineering teams validate AI behavior before users become the first testers.
Pytest for AI Agents.
