In the dependency override we set a new value for the `admin_email` when creating the new `Settings` object, and then we return that new object.

Then we can test that it is used.

## Тесты

Также в репозитории есть скрипт, который Вы можете запустить локально, чтобы протестировать весь код и сгенерировать отчеты о покрытии тестами в HTML:
