FWIW, I'm carrying the following patch in my local xfstests tree:
commit cb8e8d44de5bbb1d6163dfeb2b77e8f003a564da
Author: Theodore Ts'o <tytso@xxxxxxx>

common: kill the test if mkfs.ext4 in _scratch_mkfs_sized fails
If the file system size specified by test is incompatible with the
mkfs options used in the test configuration, make sure the test stops
at that point instad of doing something undefined.

I tried getting this upstream, but apparently there was pushback where
when the mkfs failed, it was considered a *feature* that the test
would run on some random scratch file system that was previously there
from before.
I didn't appreciate wasting time trying to run down test failures
caused by some completely inappropriate file system being used for a
test after _scratch_mkfs_sized failed, so I've just been carrying the
patch locally....
