<summary>Ou utilisez <code>async def</code> ...</summary>

Si votre code utilise `async` / `await`, utilisez `async def` :

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():

def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}

如果你的程式使用 `async` / `await`，請使用 `async def`：

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():
    return {"Hello": "World"}

					endpoints[i].IsLocal = isLocal
					epsResolved++
					if !foundLocal {
						foundLocal = isLocal
					}
				}
			}

			// Wait for the tick, if the there exist a local endpoint in discovery.
			// Non docker/kubernetes environment we do not need to wait.
			if !foundLocal && orchestrated {
				<-keepAliveTicker.C
			}
		}
	}

	// On Kubernetes/Docker setups DNS resolves inappropriately sometimes

def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}

Eğer kodunuzda `async` / `await` varsa, `async def` kullanalım:

@app.get("/")
async def read_root():

					timeout.LogSuccess(time.Duration(float64(time.Second) * rng.Float64()))

				to := timeout.Timeout()
				if to < time.Millisecond || to > time.Second {
					panic(to)

			}
		}()
	}
	wg.Wait()
}

func TestDynamicTimeoutHitMinimum(t *testing.T) {
	const minimum = 30 * time.Second
	timeout := newDynamicTimeout(time.Minute, minimum)

	initial := timeout.Timeout()

   * value. Otherwise, a call that passes one {@code loader} may return the result of another call
   * with a differently behaving {@code loader}. For example, a call that requests a short timeout
   * for an RPC may wait for a similar call that requests a long timeout, or a call by an

/// tip | "豆知識"

テスト関数は `async def` ではなく、通常の `def` であることに注意してください。

また、クライアントへの呼び出しも通常の呼び出しであり、`await` を使用しません。

これにより、煩雑にならずに、`pytest` を直接使用できます。

///

/// note | "技術詳細"

`from starlette.testclient import TestClient` も使用できます。
