This might help. Definitely. We're always looking for more people to add tests that expose problems to xfstests. :) We try to keep individual test runtime to as little as possible - under 5 minutes for the auto group, under 15s for the quick group, but by the looks of it the test you are running doesn't take that long to run. FWIW, there are already tests that cause worst case filesystem fragmentation as part of their test setup (e.g. test 042) but the coverage of such issues could definitely be improved. Also, the way we generate fragmented filesystems - by writing files and then removing a subset - could be greatly sped up by preallocation and hole punching. There's no need to write data when we could just use unwritten extents to do the same thing...
