Escreva instruções `assert` simples com as expressões Python padrão que você precisa verificar (novamente, `pytest` padrão).

/// tip | Dica

Observe que as funções de teste são `def` normais, não `async def`.

E as chamadas para o cliente também são chamadas normais, não usando `await`.

Write simple `assert` statements with the standard Python expressions that you need to check (again, standard `pytest`).

/// tip

Notice that the testing functions are normal `def`, not `async def`.

And the calls to the client are also normal calls, not using `await`.

Використовуйте об'єкт `TestClient` так само як і `httpx`.

Записуйте прості `assert`-вирази зі стандартними виразами Python, які потрібно перевірити (це також стандарт для `pytest`).

{* ../../docs_src/app_testing/tutorial001.py hl[2,12,15:18] *}


/// tip | Порада

Зверніть увагу, що тестові функції — це звичайні `def`, а не `async def`.

Виклики клієнта також звичайні, без використання `await`.

            int encoded = lock.encode(buffer, 10);

            assertEquals(24, encoded);
            assertEquals(offset, SMBUtil.readInt8(buffer, 10));
            assertEquals(length, SMBUtil.readInt8(buffer, 18));
            assertEquals(flags, SMBUtil.readInt4(buffer, 26));
            assertEquals(0, SMBUtil.readInt4(buffer, 30));
        }

        @Test
        @DisplayName("Should encode with all lock flags")

The same way, you can declare responses of lists of objects.

For that, use the standard Python `typing.List` (or just `list` in Python 3.9 and above):

{* ../../docs_src/extra_models/tutorial004_py39.py hl[18] *}

## Response with arbitrary `dict` { #response-with-arbitrary-dict }

You can also declare a response using a plain arbitrary `dict`, declaring just the type of the keys and values, without using a Pydantic model.
