I've at least said this twice in this thread.

I.e. in a feature you most likely test the uapi so 13/13.

In a bug fix you test kernel with and without the patch. Generally you
test stuff that you can observe.

You can also test non-uapi behaviour with e.g. kprobes or measure
e.g. performance, depending on patch.
