Should this be private?

category_slots = [[]] * len(TestConfiguration.category_order())

or

category_slots = map(lambda x: [], TestConfiguration.category_order())

This will give you a somewhat unexpected effect of having one array listed N times:

>>> a = ([[]] * 10)
>>> a[0].append('zoot')
>>> a
[['zoot'], ['zoot'], ['zoot'], ['zoot'], ['zoot'], ['zoot'], ['zoot'], ['zoot'], ['zoot'], ['zoot']]

Now, _that_ is cool.

No, I use it to populate the specifier in TestConfigurationConverter.
