class_docstr: Test various APIs that have been changed in 1.0.
  
  We also test whether a converted file is executable. test_file_v0_11.py
  aims to exhaustively test that API changes are convertible and actually
  work when run with current TensorFlow.
code: def testReorder(self):
      text = "tf.concat(a, b)\ntf.split(a, b, c)\n"
      _, unused_report, unused_errors, new_text = self._upgrade(text)
      self.assertEqual(
          new_text,
          "tf.concat(axis=a, values=b)\n"
          "tf.split(axis=a, num_or_size_splits=b, value=c)\n",
