...и писать дальше тесты, как и раньше.

## Тестирование: расширенный пример { #testing-extended-example }

Теперь давайте расширим наш пример и добавим деталей, чтоб посмотреть, как тестировать различные части приложения.

### Расширенный файл приложения **FastAPI** { #extended-fastapi-app-file }

Örneğin, Pydantic model kullanan ve özel bir `description` içeren `404` status code'lu bir response tanımlayabilirsiniz.

Ayrıca `response_model`'inizi kullanan, ancak özel bir `example` içeren `200` status code'lu bir response da tanımlayabilirsiniz:

{* ../../docs_src/additional_responses/tutorial003_py310.py hl[20:31] *}

                List<WebConfig> configs = new ArrayList<>();
                WebConfig config = new WebConfig();
                // Set required properties to prevent skip
                config.setUrls("http://example.com");
                configs.add(config);
                return configs;
            }

            @Override
            public List<FileConfig> getFileConfigListByIds(List<String> fileConfigIdList) {

                    // Remove leading slash for the tuple value
                    String path = paths[i].startsWith("/") ? paths[i].substring(1) : paths[i];
                    result[i] = new Tuple3<>("Host", "host" + i + ".example.com", path);
                }
                return result;
            }
        });
    }

Şimdi `/users/me` path’inde `GET` operasyonunu kullanın.

Kullanıcınızın verisini şöyle alırsınız:

```JSON
{
  "username": "johndoe",
  "email": "johndoe@example.com",
  "full_name": "John Doe",
  "disabled": false,
  "hashed_password": "fakehashedsecret"
}
```

**FastAPI** 會保留 `responses` 提供的額外資訊，並把它和你模型的 JSON Schema 結合。

例如，你可以宣告一個狀態碼為 `404` 的回應，使用一個 Pydantic 模型，並帶有自訂的 `description`。

以及一個狀態碼為 `200` 的回應，使用你的 `response_model`，但包含自訂的 `example`：

{* ../../docs_src/additional_responses/tutorial003_py310.py hl[20:31] *}

以上都會被結合並包含在你的 OpenAPI 中，並顯示在 API 文件：

<img src="/img/tutorial/additional-responses/image01.png">

        Map<String, Object> doc = new HashMap<>();
        doc.put("lang", "ja");
        doc.put("title", "タイトル");
        doc.put("content", 123); // Non-string content
        doc.put("url", "http://example.com"); // Field not in langFields

        languageHelper.updateDocument(doc);

        assertEquals("ja", doc.get("lang"));
        assertEquals("タイトル", doc.get("title_ja"));

El código real del callback dependerá mucho de tu propia aplicación API.

Y probablemente variará mucho de una aplicación a otra.

Podría ser solo una o dos líneas de código, como:

```Python
callback_url = "https://example.com/api/v1/invoices/events/"
httpx.post(callback_url, json={"description": "Invoice paid", "paid": True})
```

    val bytes = "820b6578616d706c652e636f6d".decodeHex()
    assertThat(CertificateAdapters.generalName.fromDer(bytes))
      .isEqualTo(generalNameDnsName to "example.com")
    assertThat(CertificateAdapters.generalName.toDer(generalNameDnsName to "example.com"))
      .isEqualTo(bytes)
  }
