Those are good points - .r is the extension that I really want as it
would have saved me much frustration trying to figure out why my tests
weren't running. An alternative would be to report
* checking tests ...
No test files found
rather than
* checking tests ...
OK
in the case in which there are no files run in the tests directory.
