<summary>Или используйте <code>async def</code>...</summary>

Если ваш код использует `async` / `await`, используйте `async def`:

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

from fastapi import FastAPI

app = FastAPI()


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

				return fmt.Errorf("unable to load the user `%s`: %w", userName, err)
			}
			userIdentities[index] = user
			return nil
		}, index)
	}

	err := errors.Join(g.Wait()...)
	return userIdentities, err
}

func (iamOS *IAMObjectStore) loadUser(ctx context.Context, user string, userType IAMUserType, m map[string]UserIdentity) error {
	u, err := iamOS.loadUserIdentity(ctx, user, userType)

        env:
          POSTGRES_PASSWORD: gorm
          POSTGRES_USER: gorm
          POSTGRES_DB: gorm
          TZ: Asia/Shanghai
        ports:
          - 9920:5432
        # Set health checks to wait until postgres has started
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5

    steps:

        doThrow(new RuntimeException(new InterruptedException("Interrupted"))).when(transport).connect();

        // Should throw exception due to interrupted wait
        assertThrows(RuntimeException.class, () -> tree.treeConnect(null, null));
    }

      val call = effects.callsToExecute[i]

      // If the newly-enqueued call is already out, skip its dispatcher queue events. We only
      // publish those events for calls that have to wait.
      if (call === enqueuedCall) {
        callDispatcherQueueStart = false
      } else {
        call.call.eventListener.dispatcherQueueEnd(call.call, this)
      }

      if (executorIsShutdown) {

                        }
                    } finally {
                        latch.countDown();
                    }
                }).start();
            }

            latch.await(5, java.util.concurrent.TimeUnit.SECONDS);
            assertEquals(5, successCount.get(), "All concurrent calls should succeed");
        }
    }

チェックしたい Python の標準的な式と共に、シンプルに `assert` 文を記述します。

/// 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。

Это не важно. **FastAPI** знает, что делать.

/// note | Примечание

Если вы не уверены, посмотрите раздел [Async: *"In a hurry?"*](../../async.md#in-a-hurry){.internal-link target=_blank} о `async` и `await` в документации.

## Интеграция с OpenAPI { #integrated-with-openapi }

Все объявления запросов, проверки и требования ваших зависимостей (и подзависимостей) будут интегрированы в ту же схему OpenAPI.

 *       next task will wait for any running callable (or pending {@code Future} returned by an
 *       {@code AsyncCallable}) to complete, without interrupting it (and without calling {@code
 *       cancel} on the {@code Future}). So beware: <i>Even if you cancel every preceding {@code
 *       Future} returned by this class, the next task may still have to wait.</i>.
