As this is indeed a patch, "modify" is implied. Perhaps:

This patch is doing so much that it's difficult to review for
correctness. Taking [1] into consideration, better would be to split
it into at least three patches:
1. Factor out code into test_rebase_autostash() and modify the four
tests to call it.
2. Factor out code into test_rebase_autostash_fail() and modify the
three tests to call it.
3. Fold the two "pull $i (without --rebase) is illegal" tests into a for-loop.

In the spirit of patch 3/5 and [1], you could grep for a substring
rather than the full message, but that's a minor point, not worth a
re-roll.

I don't care too strongly, but I'm not convinced that this for-loop is
buying you much for these two cases since each test already has been
reduced to two simple lines, and the added abstraction of the for-loop
increases cognitive load a bit.

You might then ask why I suggested[1] the for-loop in this case but
not for the true/false case. Even though these are also two-line
tests, they are not quite as simple as two lines down to which the
true/false tests devolve. Anyhow, this alone is not worth a re-roll.
