# 测试

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>。
