# 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] *}

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 }

  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 =

# 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] *}
