Bingo! Intercepting the output from unittest does the trick. And I have to diddle that output anyway to neutralize the displayed time since the test run times would vary between users. Here's my quick hack:

if __name__ == '__main__':
    # find all tests in this module
    import __main__
    suite = unittest.TestLoader().loadTestsFromModule(__main__)
    with io.StringIO() as buf:
        # run the tests
        with contextlib.redirect_stdout(buf):
            unittest.TextTestRunner(stream=buf).run(suite)
        # process the results - neutralise the time taken
        # since this can vary depending on the phases of the moon
        result = buf.getvalue()
        start = result.find(' in ') + len(' in ')
        end = result.find('s', start, len(result))
        result = result.replace(result[start:end], 'X.XXX')
        print(result)

It needs re-packaging into a more useful form. What's a bit curious is that it redirects stdout (also works with stderr), but it works.

Thanks a bunch for your quick and insightful help!
