컨트랙트

• assert TestClient targets http://testserver, so the contract runs with network off and no DNS sockets
• assert jsonable_encoder([item], exclude_defaults=True) excludes default fields from items in top-level lists
• assert jsonable_encoder({'item': item}, exclude_defaults=True) propagates exclude_defaults into dict values instead of leaking default fields
• assert jsonable_encoder({'items': [item]}, exclude_defaults=True) propagates exclude_defaults through dicts containing lists
• assert jsonable_encoder({'data': {'items': [item]}}, exclude_defaults=True) propagates exclude_defaults through deeply nested dicts
• assert jsonable_encoder preserves default fields when exclude_defaults is False or omitted
• assert jsonable_encoder preserves non-default overridden fields when exclude_defaults is True
• assert exclude_defaults=True strips fields explicitly assigned their default value whereas exclude_unset=True retains them
• assert jsonable_encoder excludes defaults from nested Pydantic container models inside dictionaries
• assert jsonable_encoder({'data': null_model}, exclude_none=True) excludes None fields consistently
• assert FastAPI route responses returning dicts with exclude_defaults=True omit default fields over the wire
