# Testing

Thanks to <a href="https://www.starlette.io/testclient/" class="external-link" target="_blank">Starlette</a>, testing **FastAPI** applications is easy and enjoyable.

It is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, which in turn is designed based on Requests, so it's very familiar and intuitive.

!!! tip "Tipp"
    Der eigentliche Callback ist nur ein HTTP-Request.

    Wenn Sie den Callback selbst implementieren, können Sie beispielsweise <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> oder <a href="https://requests.readthedocs.io/" class="external-link" target="_blank">Requests</a> verwenden.

Der `TestClient` basiert auf <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> und glücklicherweise können wir ihn direkt verwenden, um die API zu testen.

## Beispiel

感谢 <a href="https://www.starlette.io/testclient/" class="external-link" target="_blank">Starlette</a>，测试**FastAPI** 应用轻松又愉快。

它基于 <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>， 而HTTPX又是基于Requests设计的，所以很相似且易懂。

有了它，你可以直接与**FastAPI**一起使用 <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a>。
