Does it have this sequence: previous rerere activity (whatever that is) test_must_fail git stash apply git mergetool and demonstrate that git mergetool fails because there is a wrong rerere state in the repository after git stash apply returns? Or perhaps you are relying on the state that is left by the previous test piece? The previous edition of this patch explicitly created the condition which would confuse mergetool by creating a conflict and resolving it. The mergetool confusion is what I was testing and is what lead to this patch series. But I have since learned that rerere _can_ be effective after a stash conflict, but it was not invoked automatically. This series aims to fix that instead of simply forcing rerere to clean up in the stash conflict case. I left the concern in the commit message because this is more than a missing feature; under certain conditions, it is a bug. But I could have reworded it to be more clear. I am not relying on a prior condition to exist. In fact the 'git reset' at the start of this test will clear the previous rerere state that I am testing for in this test. In the previous edition, the test was this: Verify mergetool is (not) confused by unclean rerere behavior: 1. Set up a normal merge-conflict with rerere so that MERGE_RR exists 2. Set up a conflicted stash-pop 3. Confirm/test the aberrant behavior of mergetool In this edition, the aim of the test is different: Verify rerere is (not) called by a conflict stash-apply: 1. Set up a conflicted stash-pop 2. Confirm/test whether rerere tracks the result Also, the next test expected us to finish up with a reset, which is impossible to do if we fail (as we must) and it's an unreasonable expectation anyway.

[PATCH v2 1/2] test: git-stash conflict sets up rerere
Add a failing test to confirm a conflicted stash apply invokes rerere to record the conflicts and resolve the the files it can. In this failing state, mergetool may be confused by a left-over state from previous rerere activity. Also, the next test expected us to finish up with a reset, which is impossible to do if we fail (as we must) and it's an unreasonable expectation anyway. Begin the next test with a reset of his own instead.
