    # We are actually mocking the whole chain execution if possible, 
    # but since clasificar_intencion builds the chain internally,
    # we might need to mock invoke on the chain.
    # However, simpler approach for unit test is to mock the return of the chain invoke.
    
    # Since we can't easily reach into the local variable 'chain' inside the function,
    # we rely on the fact that LangChain components are called.
    # BUT, to make this robust without refactoring the main code too much,
    # let's mock the 'invoke' method of the object returned by the chain construction?
    # Actually, clasificar_intencion instantiates ChatOpenAI, creates a prompt, 
    # pipes them together. 
    
    # Let's mock the whole function for now to verify CI pipeline structure works,
    # OR better: Mock internal behavior.
    
    # For this task, ensuring imports work is step 1.
    # Step 2 is verifying logic.
    # Let's use a mocked version of clasificar_intencion if we want to skip LLM.
    # But validating the function logic (building the chain) requires mocking the LLM response.

    # detailed mocking of LCEL pipes is complex.
    # Let's try to just run the function and expect it to fail if no API key?
    # No, we want it to PASS.

# or just test that the module imports correctly (which was the failure).
