Controller testing with Rspec rails

[ruby rails]

Hi,

I have written some controller methods and testing it using Rspec. I am
just learning the Rspec by testing those methods. I need some hints on
how to do it. I have the below method in my QueueItemsController and I
need to test it. So how do I proceed. Please help. I read the tutorials
and other online forums but it seems to be confusing at some point.

def next
@receiver = @queue.pop()
unless @receiver.nil?
respond_with(@receiver)
else
render :json =>{"msg"=>"No more Items in the Queue to
retrieve..!!"}
end
end

In  a nutshell you think of the possible case, what the outcome should be and how do you want to test that the outcome was as expected.

For example, one of those cases could be

context 'the queue is empty' do

  before(:each) do

    #some setup so that @queue.pop will return nil

  end

  it 'should render a json message' # change this title to be something descriptive

    get :next #add params if applicable

    ActiveSupport::JSON.parse(response.body).should == {"msg"=>"No more Items in the Queue to 

retrieve..!!"} 

  end

end
