As Johannes said, this is a bit too strict to insist that E *must* get dist 0, when the only thing we may care about are e2 and e7 get the same dist value, which is larger than the dist value given to E, etc. If we wanted to ease the over-strictness, we could omit " (dist=N)" from the 'expect' file, and then sed -e 's/ (dist=[0-9]*)$//' actual | sort >actual.sorted && sort expect >expect.sorted && test_cmp expect.sorted actual.sorted && to compare only the object names. This over-strictness would have caught a bug in Git if we reverted this new feature (i.e. "rev-list --first-parent --bisect-all" does not refuse to work---it just does not do what we expect), which gives distance of -1 in the output (!). From that point of view, I think it is also OK for the test to be spelling the values out like the above. > + # Make sure the entries are sorted in the dist order > + sed -e "s/.*(dist=\([0-9]*\)).*/\1/" actual >actual.dists && > + sort -r -n actual.dists >actual.dists.sorted && I forgot to mention but I added "-n" here to make sure we numerically sort the list of distance values. Also you had a bogus regexp to catch digits inherited from "something like this" I showed in an older discussion (I think it is sufficient to say [0-9]* here). The above makes sure that commits that have larger distance number are listed earlier in the output, and we do not care if which one of e4 or e5, both of which have distant number 4, is shown first---we'd be happy as long as all the ones at distance 4 are shown before the others at smaller distance number. So with this in place, I think we can omit the exact distance number from the earlier part of this test, but as I said, it would have caught the bug that produces a negative distance value in the output, so I am still on the fence, leaning a bit toward being stricter than necessary. > + test_cmp actual.dists.sorted actual.dists > +' > + > test_done
