Depends entirely on the package in question.

Sure, of completely no surprise a lot of package unit tests don’t really
do much that’s particularly interesting save to the package itself.

There are sometimes an interesting subset that drives some amount of work in kernel.
That’s the useful stuff.

Take bluez, and it’s use of CONFIG_CRYPTO_USER_API.

So if there’s some useful subset, that’s what I’m looking for.

Past regressions make for a good test.

Good feedback, thanks.
