# Тестирование

Благодаря <a href="https://www.starlette.io/testclient/" class="external-link" target="_blank">Starlette</a>, тестировать приложения **FastAPI** легко и приятно.

Тестирование основано на библиотеке <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, которая в свою очередь основана на библиотеке Requests, так что все действия знакомы и интуитивно понятны.

      if (!endpointPair.isOrdered()) {
        return false;
      }

      Object source = endpointPair.source();
      Object target = endpointPair.target();
      return (node.equals(source) && graph.successors(node).contains(target))
          || (node.equals(target) && graph.predecessors(node).contains(source));
    } else {
      if (endpointPair.isOrdered()) {
        return false;
      }

### Install `pydantic-settings`

First, make sure you create your [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install the `pydantic-settings` package:

<div class="termy">

```console

## Anwendungsfälle

Einige Anwendungsfälle sind:

* Konvertieren von Nicht-JSON-Requestbodys nach JSON (z. B. <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Dekomprimierung gzip-komprimierter Requestbodys.
* Automatisches Loggen aller Requestbodys.

## Handhaben von benutzerdefinierten Requestbody-Kodierungen

사용자 정의 헤더는 <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">'X-' 접두사를 사용</a>하여 추가할 수 있습니다.

그러나 만약 클라이언트의 브라우저에서 볼 수 있는 사용자 정의 헤더를 가지고 있다면, 그것들을 CORS 설정([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank})에 <a href="https://www.starlette.io/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette CORS 문서</a>에 명시된 `expose_headers` 매개변수를 이용하여 헤더들을 추가하여야합니다.
