Subject: custom assertion message for unit tests

I'm having trouble trying to figure out how to customize an assertion
message when running unit tests.  In particular, I want to check the
permissions on a file, so I have something like:

assert_equal(0755, File.stat(test_file).mode & 0777)

If it fails, I get a message like:

<493> expected but was
<420>.

and of course I would like the expected and actual permissions to be
displayed in octal rather than decimal.  How can I do that?
