For the tests that need DISPLAY, the usual thing we do here is to spawn
an Xvfb for display :1 and set DISPLAY accordingly.  There are several
variants depending on what exactly else you need (some with dbus, some
without), simply grep for "xorg-server-for-tests" and you ought to find
one that fits your needs.

Once we find out the packages that fail regardless, that have no easy
fix, it is still acceptable to fix a few failing tests manually by
patching the test suite, or if all else fails use `#:tests? #f' with an
appropriate comment.
