So the test always fails due to a mismatch with this expected golden output:
-Label: none uuid: <UUID>
+Label: none uuid: <UUID>
Total devices <NUM> FS bytes used <SIZE>
devid <DEVID> size <SIZE> used <SIZE> path SCRATCH_DEV
devid <DEVID> size <SIZE> used <SIZE> path /dev/mapper/error-test
The extra space after "uuid:" comes from _filter_uuid:
sed -e "s/\(uuid[ :=]\+\) *[0-9a-f-][0-9a-f-]*/\1 <UUID>/ig"
Which gets \1 with the string "uuid: " and then does "uuid: " + " " + "<UUID>".
We need to either to fix the golden output here or _filter_uuid (and
make sure it doesn't break any other tests using it directly or
indirectly such as yours).
Other than that, the test looks good and when fixed you can add:
