Replace the DEFAULT_* test helpers by functions, as they don't need the exta flexibility.

is this change going to affect the behaviour? if so, please document it in the patch description
No, previously the absence of a key in the vararg would denote there not being a key, now that a function is used there is an explicit no key argument, which is checked here to see if we use key checking or not
