It sounds like what you're looking for is FunctionTestCase
(http://docs.python.org/lib/unittest-contents.html). Using that, your
loop above becomes something like

for testFunc, expectedResult in MyTestData:
         def tester():
             self.assertEqual(testFunc(), expectedResult)
         suite.addTest(FunctionTestCase(tester))
