I've been running tests individually as

Fixed. It would be great if there were a pre-commit hook that I could
install to prevent this from ever getting committed.

Add some more cases.

Comparing exact outputs is IMO an antipattern in general. It makes the
test more fragile than they need to be. (what if we change the
"remote: " prefix to something else for example?).
If using a golden output, the second test would either require a
repetitive, too long golden file, or it would use loose greps anyway.
Added a comment.
