# Geschichte, Design und Zukunft

Vor einiger Zeit fragte <a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">ein **FastAPI**-Benutzer</a>:

> Was ist die Geschichte dieses Projekts? Es scheint, als wäre es in ein paar Wochen aus dem Nichts zu etwas Großartigem geworden [...]

Hier ist ein wenig über diese Geschichte.

# История создания и дальнейшее развитие

Однажды, <a href="https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920" class="external-link" target="_blank">один из пользователей **FastAPI** задал вопрос</a>:

> Какова история этого проекта? Создаётся впечатление, что он явился из ниоткуда и завоевал мир за несколько недель [...]

Что ж, вот небольшая часть истории проекта.

## Альтернативы

O `TestClient` é baseado no <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, e felizmente nós podemos utilizá-lo diretamente para testar a API.
