AI writes code. AI writes tests. What could go wrong?
Mutation testing result: 85% of bugs caught.
After hiding the implementation from the AI: 92%.
Property tests found 11 real bugs all others missed.

"Just use a different LLM for tests."
Doesn't work.
The moment any LLM sees your code, it reasons about what it does, not what it should do.
Independence needs different information, not different systems.

At 39C3, Rehberger showed AI coding assistants getting hijacked via prompt injection. He calls them "ZombAIs."
When AI writes code AND tests, that's not verification.

I used a product image of a jacket and placed a generated car in front of the jacket. Therefore, I used #ControlNet and #StableDiffussion and then mixed everything together. Unfortunately the denim jacket doesn't fit to a fast car.
