When running ERT tests in batch mode, the conservative values
chosen for `print-level` and `print-length` sometimes make it
difficult to see what exactly is wrong. This patch introduces
two new variables (`ert-batch-print-level` &
`ert-batch-print-length`) that one can use to customize them;
e.g.
emacs -batch -l ert -l my-tests.el \
--eval "(let ((ert-batch-print-level 10) \
(ert-batch-print-length 120)) \
(ert-run-tests-batch-and-exit))"
Sounds like a good idea.
+MESSAGE-FN should normally be nil; it is used for automated

I don't understand this bit, though. If you want to test how
this
function outputs messages, you can just `cl-letf' like this:
(cl-letf (((symbol-function 'message) ...
