So there are two states that we consider, one is a "base" state that we get the device into before we run the test. This is done in the `cleanUp` method in `gaia_test.py`. Generally there we aim to un-set and parameters that tests might have set, clear out the cache or set things to a known consistent state (for example the timezone). In here we would like to disable the screenreader.

The 2nd state is the setUp of the test which is where you want to be enabling the screenreader in anticipation of the test method ahead.

In the "rest of it" :) I am talking about why we set these settings before the test rather than after the test.
