> "write some unit tests for Redux today"

The equivalent of "draw me a dog" -> not a masterpiece!? who would have thought? You need to come up with a testing methodology, write it down, and then ask the model to go through it. It likes to make assumptions on unspecified things, so you got to be careful.

More fundamentally I think testing is becoming the core component we need to think about. We should not vibe-check AI code, we should code-check it. Of course it will write the actual test code, but your main priority is to think about "how do I test this?"

You can only know the value of a code up to the level of its testing. You can't commit your eyes into the repo, so don't do "LGTM" vibe-testing of AI code, it's walking a motorcycle.
