# Тестирование { #testing }

Благодаря <a href="https://www.starlette.dev/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.

### Einstellungen und Tests { #settings-and-testing }

Dann wäre es sehr einfach, beim Testen ein anderes Einstellungsobjekt bereitzustellen, indem man eine Abhängigkeitsüberschreibung für `get_settings` erstellt:
