<summary>Or use <code>async def</code>...</summary>

If your code uses `async` / `await`, use `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"}

            settingsBuilder.put("http.cors.enabled", true);
            settingsBuilder.put("discovery.type", "single-node");
        }).build(newConfigs().clusterName(clusterName).numOfNode(1));

        // wait for yellow status
        runner.ensureYellow();

        System.setProperty(FesenClient.HTTP_ADDRESS, "localhost:" + runner.node().settings().get("http.port", "9201"));

        super.setUp();
    }

    @Override

            });
        }

        // Start all threads simultaneously
        for (Thread thread : threads) {
            thread.start();
        }

        // Wait for all threads to complete
        for (Thread thread : threads) {
            thread.join();
        }

        // All threads should see the initialized state
        for (boolean result : initResults) {

					} else {
						offlineEndpoints = append(offlineEndpoints, fmt.Errorf("%s is unreachable: %w", clnt, err))
					}
				} else {
					onlineServers++

				mu.Unlock()
			}(clnt)
		}
		wg.Wait()

		select {
		case <-ctx.Done():
			return ctx.Err()
		default:
			// Sleep and stagger to avoid blocked CPU and thundering
			// herd upon start up sequence.

                        }
                    } 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.
