Try this:

import types
import sys

# TestTask...

for task in [Task1, Task2]:
    name = "TestTask%s" % Task1.__name__
    def setUp(self):
        self.t = task
    setattr(sys.modules[__name__], name, types.ClassType(name,
(TestTask,), {'setUp': setUp}))

A bit crude, I know, but should save you from copy&paste.
