In fact it *cannot* behave the same because we're trying to test the non-commit-graph flow there. Since i'm dropping it in v3 I won't worry too much about it. As you said, if you are removing the test, it is a moot point, but I think what Derrick suggests is to do something like this: diff --git c/t/t6120-describe.sh w/t/t6120-describe.sh index c353c21cc8..871bdbbec9 100755 --- c/t/t6120-describe.sh +++ w/t/t6120-describe.sh @@ -508,6 +508,7 @@ test_expect_success 'name-rev without commitGraph does not handle non-monotonic cd non-monotonic && rm -rf .git/info/commit-graph* && + sane_unset GIT_TEST_COMMIT_GRAPH && echo "main~3 undefined" >expect && git name-rev --tags main~3 >actual && where you want to decline using the commit-graph feature. As this test piece is already in its own subshell, the unsetting will affect only this one.
