We’re mandated to use it at my work. For unit tests it can really go wild and it’ll write thousands of lines of tests to cover a single file/class for instance whereas a developer would probably only write a fourth as much. You have to be specific to get any decent output from them like “write a test for this function and use inputs x and y and the expected output is z”

Personally I like writing tests too and I think through what test cases I need based on what the code is supposed to do. Maybe if there are annoying mocks that I need to create I’ll let the AI do that part or something.
