You probably need to change this line:
    self.assertRaises(ValueError(), duffer())
to this:
    self.assertRaises(ValueError, duffer)

In this case, the ValueError was not raised by "duffer" as intended. 
Instead it was raised because you passed duffer() to assertRaises,
which expects a callable object.
