Quando você precisa que o `lifespan` seja executado em seus testes, você pode utilizar o `TestClient` com a instrução `with`:

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

Você pode ler mais detalhes sobre o ["Executando lifespan em testes no site oficial da documentação do Starlette."](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)

  public void testNullPointers() {
    NullPointerTester tester = new NullPointerTester();

    tester.testAllPublicInstanceMethods(new ImmutableMap.Builder<Object, Object>());
    tester.testAllPublicInstanceMethods(ImmutableMap.of());
    tester.testAllPublicInstanceMethods(ImmutableMap.of("one", 1));
    tester.testAllPublicInstanceMethods(ImmutableMap.of("one", 1, "two", 2, "three", 3));

# Asynchrone Tests { #async-tests }

Sie haben bereits gesehen, wie Sie Ihre **FastAPI**-Anwendungen mit dem bereitgestellten `TestClient` testen. Bisher haben Sie nur gesehen, wie man synchrone Tests schreibt, ohne `async`-Funktionen zu verwenden.

# Async Tests { #async-tests }

You have already seen how to test your **FastAPI** applications using the provided `TestClient`. Up to now, you have only seen how to write synchronous tests, without using `async` functions.

### Eine *Pfadoperation* erstellen, um es zu testen { #create-a-path-operation-to-test-it }

Um nun testen zu können, ob alles funktioniert, erstellen Sie eine *Pfadoperation*:

### Es testen { #test-it }
