test_tool_calling

To disable tool calling tests, set has_tool_calling to False in your test class:

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

If this test fails, check that bind_tools is implemented to correctly translate LangChain tool objects into the appropriate schema for your chat model.

This test may fail if the chat model does not support a tool_choice parameter. This parameter can be used to force a tool call. If tool_choice is not supported and the model consistently fails this test, you can xfail the test:

@pytest.mark.xfail(reason=("Does not support tool_choice."))
def test_tool_calling(self, model: BaseChatModel) -> None:
    super().test_tool_calling(model)

Otherwise, in the case that only one tool is bound, ensure that tool_choice supports the string 'any' to force calling that tool.
