# Avoid problems when running Capybara specs before regular ones, and fix the
# "Could not find a valid mapping for X". Part of the  solution is to use the
# Devise test helpers as explained on link A, but then you need to clear the
# fabricated objects, as explained on link B. Here's the equivalent code when
# using the Fabrication gem

Step 0:

Get Homebrew installed on your mac if you don't already have it

Step 1:

Install highlight. "brew install highlight". (This brings down Lua and Boost as well)

Step 2:

#Model 

@user.should have(1).error_on(:username) # Checks whether there is an error in username 
@user.errors[:username].should include("can't be blank")  # check for the error message 

#Rendering
response.should render_template(:index)

#Redirecting 
response.should redirect_to(movies_path)

  #Problem:
  #In rails 3.0.1+ it is no longer possible to do this anymore;
  #  rescue_from ActionController::RoutingError, :with => :render_not_found
  #
  #The ActionController::RoutingError thrown is not caught by rescue_from.
  #The alternative is to to set a catch-all route to catch all unmatched routes and send them to a method which renders an error
  #As in http://techoctave.com/c7/posts/36-rails-3-0-rescue-from-routing-error-solution
