### Settings and testing { #settings-and-testing }

Then it would be very easy to provide a different settings object during testing by creating a dependency override for `get_settings`:

{* ../../docs_src/settings/app02_an_py310/test_main.py hl[9:10,13,21] *}

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.
