test_image_tool_message

Test that the model can process ToolMessage objects with image inputs.

This test should be skipped if the model does not support messages of the Chat Completions image_url format:

ToolMessage(
    content=[
        {
            "type": "image_url",
            "image_url": {"url": f"data:image/jpeg;base64,{image_data}"},
        },
    ],
    tool_call_id="1",
    name="random_image",
)

In addition, models should support the standard LangChain ImageContentBlock format:

ToolMessage(
    content=[
        {
            "type": "image",
            "base64": image_data,
            "mime_type": "image/jpeg",
        },
    ],
    tool_call_id="1",
    name="random_image",
)

This test can be skipped by setting the supports_image_tool_message property to False (see configuration below).

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