Есть альтернативный способ определить логику, которую нужно выполнить во время startup и во время shutdown.

Вы можете определить обработчики событий (функции), которые нужно выполнить до старта приложения или при его завершении.

Эти функции можно объявить с `async def` или обычным `def`.

### Событие `startup` { #startup-event }

Hay una forma alternativa de definir esta lógica para ser ejecutada durante el *startup* y durante el *shutdown*.

Puedes definir manejadores de eventos (funciones) que necesitan ser ejecutadas antes de que la aplicación se inicie, o cuando la aplicación se está cerrando.

Estas funciones pueden ser declaradas con `async def` o `def` normal.

### Evento `startup` { #startup-event }

Essas funções podem ser declaradas com `async def` ou `def` normal.

### Evento `startup` { #startup-event }

Para adicionar uma função que deve rodar antes de a aplicação iniciar, declare-a com o evento `"startup"`:

{* ../../docs_src/events/tutorial001_py39.py hl[8] *}

Nesse caso, a função de manipulador do evento `startup` inicializará os itens do "banco de dados" (apenas um `dict`) com alguns valores.

# Testing Events: lifespan and startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

When you need `lifespan` to run in your tests, you can use the `TestClient` with a `with` statement:

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}


You can read more details about the ["Running lifespan in tests in the official Starlette documentation site."](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)

# Тестирование событий: lifespan и startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

Если вам нужно, чтобы `lifespan` выполнялся в ваших тестах, вы можете использовать `TestClient` вместе с оператором `with`:

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}

# Eventos de testing: lifespan y startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

Cuando necesitas que `lifespan` se ejecute en tus tests, puedes usar el `TestClient` con un statement `with`:

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}

### Run Automatically on Startup { #run-automatically-on-startup }

In general, you will probably want the server program (e.g. Uvicorn) to be started automatically on server startup, and without needing any **human intervention**, to have a process always running with your API (e.g. Uvicorn running your FastAPI app).

  public void testStart_failed() {
    Exception exception = new Exception("deliberate");
    TestService service =
        new TestService() {
          @Override
          protected void startUp() throws Exception {
            super.startUp();
            throw exception;
          }
        };
    assertEquals(0, service.startUpCalled);
    RuntimeException e =
