Discovered the coverage.py module and put it in my small unittest testsuite for rhpl.conf.

The interesting code looks like this:

def suite():
    suite = unittest.TestSuite()
    suite = unittest.makeSuite(TestConf,'test')
    return suite
 if __name__ == "__main__":
    import coverage
    coverage.erase()
    coverage.start()
    from rhpl import Conf
    testRunner = unittest.TextTestRunner(verbosity=2)
    result = testRunner.run(suite())
    coverage.stop()
    coverage.the_coverage.report(Conf, show_missing=0 )
    sys.exit(not result.wasSuccessful())

which outputs s.th. like this:
