for dvdkit it's not too easy to produce such test set.
as it would mean writting several dvd discs, and OS emulators, so you can
test if the updated dvdkit still works on all bsd, win32 versions, with any
kind of region protection and silly driver firmwares (assuming you have one
of every major dvd drive types).

so, for this one the commit-and-wait-for-bugreports is much easier.

only in very rare cases.
anyway it's called QA, quality a...?, used by big software development
companies. also the one i worked for (few years ago) had a big team
developing test suites only. and yes, this team was actually bigger and
more busy then the other team working on the actual code.
for a single line of code they had to write several lines of testing code.
but they had to do it, as later changes/fixes to the main code must be
immediatelly tested, waiting for bugreports from customer is not an option
