>Unit tests tend to have a lot of boilerplate sometimes, often not copy-pastable

When people use LLMs to write code and they find if helpful, invariably it is because they are spewing boilerplate.

If you dont systematically eliminate boilerplate the codebase eventually turns into an unmaintainable mess.

>Sometimes you do actually want to add a ton of unit tests even if they’re a little too implementation-focused.

Really? Id consider this an antipattern.

>I find it better to treat writing tests with LLMs tactically

I find the prospect of using them to write production code / tests pretty depressing.

The best thing that can be said is that they will create lots of jobs with the mess they make.
