UserInDB(**user_dict)
```

будет эквивалентно:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Или, более точно, если использовать `user_dict` напрямую, с любым содержимым, которое он может иметь в будущем:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],

    }

    void testValidUsernames(String username) {
        assertDoesNotThrow(() -> InputValidator.validateUsername(username));
    }

    @ParameterizedTest
    @DisplayName("Test invalid usernames")
    @ValueSource(strings = { "user name", // space

Fini de taper des noms de clés erronés, de faire des allers-retours entre les documents, ou de faire défiler vers le haut et vers le bas pour savoir si vous avez finalement utilisé `username` ou `user_name`.
