class_docstr: Could use torch.testing._internal.common_utils to reduce boilerplate.
  GH CI job doesn't build torch before running tools unit tests, hence
  manually adding these parametrized tests.
code: def test_const_tensor_argument_translate_ctype_executorch(
      self,
  ) -> None:
      self._test_const_tensor_argument_translate_ctype(
          ET_UNBOXING, et_types
      )

label_desc: Use image node_id 5 for calling the TestUnboxing obj's underlying member method code with example usage: obj.test_const_tensor_argument_translate_ctype_executorch() without return types
