IMO test-lib.el changes should be in a separate patch.

At a glance, the tests look good.  Though more review of the tests
itself would be nice.

IMO this comment is misplaced.  There are other functions above which
also help to write tests e.g. `test-output.  I think we should either
remove the comment or move all test helpers in one place below the
comment (in a separate patch).

Please consider renaming to `notmuch-test-report-unexpected'.

Please consider renaming to notmuch-test-unexpected.

Previous line says "unsimilar", now it is "dissimilar".  I am not sure
which one is correct.  Also, it is not clear what "similar" means for
test results.  IMO "not equal" would be more clear.

Please consider renaming to notmuch-test-expect-equal for consistency
with shell tests.

I do not like that equality check is split between notmuch-test-compare
and notmuch-test-unsimilar.  It makes the code harder to read (took me a
while to understand why "catch all case" above does not need the
equality check).  Also, notmuch-test-unsimilar would be hard to reuse
because the comparison check is done in one case and not done in
another.  How about merging them?  The code would look something like:

  (cond
    (both are lists)
      ; code from notmuch-test-unsimilar
    (catch all case)
      (if not equal)
        (notmuch-test-report-unexpected output expected))
