assertEquals("/v1/chat/messages/3", request3.url.encodedPath)

  // Shut down the server. Instances cannot be reused.
  server.close()
}
```

Your unit tests might move the `server` into a field so you can shut it down
from your test's `tearDown()`.

#### MockResponse

Mock responses default to an empty response body and a `200` status code.

その場合は、標準の `dataclasses` を `pydantic.dataclasses` に置き換えるだけで済みます。これはドロップイン置換です:

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

1. 依然として標準の `dataclasses` から `field` をインポートします。

2. `pydantic.dataclasses` は `dataclasses` のドロップイン置換です。

3. `Author` dataclass は `Item` dataclass のリストを含みます。

4. `Author` dataclass を `response_model` パラメータとして使用しています。

            "type": "type_error.integer"
        }
    ]
}
```

вы получите текстовую версию:

```

Field: ('path', 'item_id'), Error: Input should be a valid integer, unable to parse string as an integer
