I consider that three separate unit tests:

     def testGivesTrue(self):
         for x in self.args_giving_true:
             self.assertTrue(method(x))

     def testGivesFalse(self):
         for x in self.args_giving_false:
             self.assertFalse(method(x))

     def testIsBool(self):
         for x in self.args_giving_true + self.args_giving_false:
             self.assertTrue(isinstance(method(x), bool))
