Controller testing with Rspec rails

Rails
1

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
