You can try something like this (not tested):
>>> for S in InvalidStrings:
... self.assertRaises(DB.InvalidConnectString, DB.DB, *S)
Here the * operator unpacks a sequence when passed in to a function that
is expecting positional arguments. See the Python Tutorial, 4.7.4
Unpacking Argument Lists for a better explanation.
