From: Derrick Stolee <derrickstolee@xxxxxxxxxx> The tests added by d2ba271aad0 (branch: check for bisects and rebases, 2022-06-14) modified hidden state to verify the branch_checked_out() helper. While this indeed checks that the method implementation is _as designed_, it doesn't show that it is _correct_. Specifically, if 'git bisect' or 'git rebase' change their back-end for preserving refs, then these tests do not demonstrate that drift as a bug in branch_checked_out(). Modify the tests in t2407 to actually rely on a paused bisect or rebase. This requires adding the !SANITIZE_LEAK prereq for tests using those builtins. The logic is still tested for leaks in the final test which does set up that back-end directly for an error state that should not be possible using Git commands.
