Test code is total: we require it to always terminate or it's a failure! It also typically has 100% line and branch coverage. I feel way less nervous about refactoring tests, you can always just run them.

It feels like rename is by far the most important refactoring operation. If I had an IDE with only one refactoring, I think I'd want rename.

... and my third refactoring with Cursor changed some function calls that I didn't want it to modify. Subtle. I've had the most success with AI coding tools when I know exactly what I want the output to look like.
