I prefer the API for the ‘testscenarios’ library
<URL:https://launchpad.net/testscenarios>, where each scenario has a
name and an arbitrary dict of the scenario parameters
<URL:http://bazaar.launchpad.net/~lifeless/testscenarios/trunk/annotate/head%3A/README>.

    scenarios = [
        ('foo', {'spam': True, 'eggs': 17, 'beans': [0, 1]}),
        ('bar', {'spam': False, 'eggs': 23, 'beans': [1, 1, 0]}),
        ]
