导入 `TestClient`.

通过传入你的**FastAPI**应用创建一个 `TestClient` 。

创建名字以 `test_` 开头的函数（这是标准的 `pytest` 约定）。

像使用 `httpx` 那样使用 `TestClient` 对象。

为你需要检查的地方用标准的Python表达式写个简单的 `assert` 语句（重申，标准的`pytest`）。

```Python hl_lines="2  12  15-18"
{!../../docs_src/app_testing/tutorial001.py!}
```

/// tip | "提示"

注意测试函数是普通的 `def`，不是 `async def`。

还有client的调用也是普通的调用，不是用 `await`。
