You can either specify `foo` so it'll create `foo0, foo1 ... fooN` files in the working directory, but you can also specify `my/dir/foo` to get the same files (`foo0, foo1 ... fooN`) written in `my/dir` directory. So, I guess it's both in a way. Should I call it `validationPathPrefix`? Clarify this in the comment? Or do you have any other suggestions?
