I did actually use the LLM to write tests, and was pleased to see the results, which I thought were pretty good and thorough, though clearly the author of this blog post has a different opinion.

But TDD is not the way I think. I've never been able to work that way (LLM-assisted or otherwise). I find it very hard to write tests for software that isn't implemented yet, because I always find that a lot of the details about how it should work are discovered as part of the implementation process. This both means that any API I come up with before implementing is likely to change, and also it's not clear exactly what details need to be tested until I've fully explored how the thing works.

This is just me, other people may approach things totally differently and I can certainly understand how TDD works well for some people.
