I was tempted to use test_cmp_rev, which would have the same effect.
The original test checked the output of "git rev-parse start^0", while
the test as modified above checks the output of "git rev-parse
--verify start^0".
I slightly prefer the version without --verify because "git rev-parse
--verify" is well exercised elsewhere in the testsuite (but then, so
is rev-parse without --verify, so it's not a big deal).
Abbreviating as follows
foo () {
git rev-parse --verify "$1" >expect &&
git rev-parse "$2" >actual &&
test_cmp expect actual
}
would also be fine with me. All it would take is a good replacement
for the placeholder "foo". The added flexibility of "compare a rev
to the output of an arbitrary command" doesn't get used.
