+### Config and Injector Nesting
+
+A powerful feature of both [`Config`](/developer_guides/configuration/configuration/) and [`Injector`](/developer_guides/extending/injector/) is the ability to "nest" them so that you can make changes that can easily be discarded without having to manage previous values.
+
+The testing suite makes use of this to "sandbox" each of the unit tests as well as each suite to prevent leakage between tests.
+
+If you need to make changes to `Config` (or `Injector) for each test (or the whole suite) you can safely update `Config` (or `Injector`) settings in the `setUp` or `tearDown` functions.
+
+It's important to remember that the `parent::setUp();` functions will need to be called first to ensure the nesting feature works as expected.
+
+	:::php

+		parent::setUpOnce();

+		//this will be reset to 'var_value' at the end of this test function
