# 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:

## 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.
