    def test_message_with_name(self, model: BaseChatModel) -> None:
        """Test that `HumanMessage` with values for the `name` field can be handled.

        These messages may take the form:

        ```python
        HumanMessage("hello", name="example_user")
        ```

        If possible, the `name` field should be parsed and passed appropriately
        to the model. Otherwise, it should be ignored.

        ??? question "Troubleshooting"

            If this test fails, check that the `name` field on `HumanMessage`
            objects is either ignored or passed to the model appropriately.
