### Événement `shutdown` { #shutdown-event }

Pour ajouter une fonction qui doit être exécutée lorsque l'application s'arrête, déclarez-la avec l'événement « shutdown » :

{* ../../docs_src/events/tutorial002_py310.py hl[6] *}

Ici, la fonction gestionnaire de l'événement `shutdown` écrira une ligne de texte « Application shutdown » dans un fichier `log.txt`.

// Shutdown - shuts down HTTP server.
func (srv *Server) Shutdown() error {
	srv.listenerMutex.Lock()
	if srv.listener == nil {
		srv.listenerMutex.Unlock()
		return http.ErrServerClosed
	}
	srv.listenerMutex.Unlock()

	if atomic.AddUint32(&srv.inShutdown, 1) > 1 {
		// shutdown in progress
		return http.ErrServerClosed
	}

              () -> {
                service.shutdown();

# Тестування подій: тривалість життя та запуск - вимкнення { #testing-events-lifespan-and-startup-shutdown }

Коли вам потрібно, щоб `lifespan` виконувався у ваших тестах, ви можете використати `TestClient` з оператором `with`:

{* ../../docs_src/app_testing/tutorial004_py310.py hl[9:15,18,27:28,30:32,41:43] *}

# Event'leri Test Etme: lifespan ve startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

Test'lerinizde `lifespan`'ın çalışması gerektiğinde, `TestClient`'ı bir `with` ifadesiyle kullanabilirsiniz:

{* ../../docs_src/app_testing/tutorial004_py310.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_py310.py hl[9:15,18,27:28,30:32,41:43] *}

# 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`:
