#The same code at both controller can be moved to a helper and call it from a helper. This #approach would reduce our chances of customizing these messages specific to cobrand and #dashboard.
 
#--- specs --
 
#I have created a shared example group which can be reused by both DashBoard(Broker) and #CoBrand.
 
# This group should support both DashBoard and CoBrand
 
shared_examples_for "Supporting back filling messages" do
  it "should have message as 'unavailable' when state is 'busy'" do
    @controller.stub!(:init_props)# No more pre-populating values
    AppConfig.merge({"fansnap.broker.backfill" => "busy"})# Setting the value to be busy
    AppConfig.merge({"fansnap.cobrand.backfill" => "busy"})
    # Expecting that 'over riding properties through hierarchy' works fine.
    get :index, :channel_name => "fs"        
    #Check if the view has proper message
    assigns[:backfilling_message].should =~ /The Partner Portal is not currently available/
  end      
 
  it "should have no message when state is 'ok'" do
    @controller.stub!(:init_props)# No more pre-populating values
    AppConfig.merge({"fansnap.broker.backfill" => "ok"})# Setting the value to be 'ok'
    AppConfig.merge({"fansnap.cobrand.backfill" => "ok"})
    get :index, :channel_name => "fs"        
    #Check if the view has no error message
    assigns[:backfilling_message].should be_nil
  end  
end
 
and then dashboard and cobrand controllers uses it as;
  it_should_behave_like "Supporting back filling messages"
 
#Both specs are green now.
