JSON Schema在最新的一个版本中定义了一个字段 <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a> ，但是 OpenAPI 基于之前的一个旧版JSON Schema，并没有 `examples`.

所以 OpenAPI为了相似的目的定义了自己的 <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.3.md#fixed-fields-20" class="external-link" target="_blank">`example`</a> (使用 `example`, 而不是 `examples`), 这也是文档 UI 所使用的 (使用 Swagger UI).

### Normal **FastAPI** { #normal-fastapi }

First, write all your **FastAPI** application as normally:

    * 파이썬의 `datetime.timedelta`.
    * 요청과 응답에서 전체 초(seconds)의 `float`로 표현됩니다.
    * Pydantic은 "ISO 8601 시차 인코딩"으로 표현하는 것 또한 허용합니다. <a href="https://docs.pydantic.dev/latest/concepts/serialization/#json_encoders" class="external-link" target="_blank">더 많은 정보는 이 문서에서 확인하십시오.</a>.
* `frozenset`:
    * 요청과 응답에서 `set`와 동일하게 취급됩니다:
        * 요청 시, 리스트를 읽어 중복을 제거하고 `set`로 변환합니다.
        * 응답 시, `set`는 `list`로 변환됩니다.

To use, first add this library as a test dependency:

```
testImplementation("com.squareup.okhttp3:mockwebserver3-junit5:5.3.0")
```

Annotate fields in test classes with `@StartStop`. The server will be started and shut down
automatically.

```
class MyTest {

  @StartStop
  public final MockWebServer server = new MockWebServer();

  @Test
  void test() {
    ...
  }
}
```
