*****************************************************************
DEPRECATION WARNING: you are using deprecated behaviour that will
be removed from RSpec 3.

You have set some configuration options after an example group has
already been defined.  In RSpec 3, this will not be allowed.  All
configuration should happen before the first example group is
defined.  The configuration is happening at:

  #{caller[1]}
