test_structured_output_optional_param

To disable structured output tests, set has_structured_output to False in your test class:

class TestMyChatModelIntegration(ChatModelIntegrationTests):
    @property
    def has_structured_output(self) -> bool:
        return False

By default, has_structured_output is True if a model overrides the with_structured_output or bind_tools methods.

If this test fails, ensure that the model's bind_tools method properly handles Pydantic V2 models with optional parameters.

langchain_core implements a utility function. that will accommodate most formats.

See example implementation. of with_structured_output.
