The way this is phrased, it sounds almost as if Git also "guesses"
the value from config. Perhaps rephrase like this:
Instruct Git to avoid trying to guess defaults for 'user.email'
and 'user.name', and instead retrieve the values only from
configuration.

This test script still has a fair amount of unnecessary cruft in it
which obscures the important bits showing what you are really
testing. Below is a more concise version with the unnecessary stuff
removed:
