Ever wondered how to login as another user within Devise?

Recently we had a feature request that would provide Admins with the ability
to sign is as another user. You could imagine live demonstrations or even production
support calls where you would like to be signed in as another user, yet not
have to ask for or decrypt their current password. After stewing for a bit, we found a
pretty nice solution with Devise.

Here's the Cucumber feature...

require 'test_helper'

class CalendarControllerTest < ActionController::TestCase
  should route(:get, "/calendar").to(:action => :index)
  should route(:get, "/calendar/events").to(:action => :events)
  # Error:
  # functional/calendar_controller_test.rb:9: undefined local variable or
  # method `require_logged_in' for CalendarControllerTest:Class (NameError)
  should require_logged_in
  should require_logged_in.for(:events)

# A basic, synthetic benchmark of the impact HTTP client has
# on the speed of talking to ElasticSearch in the Tire gem.
#
# In general, Curb seems to be more then two times faster the RestClient, in some cases it's three
# to five times faster. I wonder if keep-alive has anything to do with it, but it probably does.
