For example:

              self.tb.run()

              self.tb.connect((src0, 0), (adder, 0))
              self.tb.connect((adder, 0), (adder, 1))
              self.tb.connect(adder, sink)
              self.tb.run()
              self.assertEqual(sink.data(), (1, 4, 9, 16, 25))

              values = (0, 'hello', 4.2, True, None, [2, 3, 4], (9, 8, 7), 1j, {2:'d'})
              src = TestUtils.TagSource(values)

Suppose I wanted the preloaded input to be 5 (instead of default 0), how
do
I do it?
