Создайте функцию, название которой должно начинаться с `test_` (это стандарт из соглашений `pytest`).

Используйте объект `TestClient` так же, как Вы используете `httpx`.

Напишите простое утверждение с `assert` дабы проверить истинность Python-выражения (это тоже стандарт `pytest`).

    // In practice, wildcards are always in the leftmost position. For now, this implementation
    // cheats and does not attempt every possible permutation. Instead, it only considers wildcards
    // in the leftmost position. We assert this fact when we generate the public suffix file. If
    // this assertion ever fails we'll need to refactor this implementation.
    var wildcardMatch: String? = null

Achten Sie auf die Methode `__init__`, die zum Erstellen der Instanz der Klasse verwendet wird:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

... sie hat die gleichen Parameter wie unsere vorherige `common_parameters`:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8] *}

Diese Parameter werden von **FastAPI** verwendet, um die Abhängigkeit „aufzulösen“.

In beiden Fällen wird sie haben:
