Rails - Jul 2011 - How to write render expectation in Controller Spec?

Hello All,
I am a rspec beginner and I am trying to find a way out to write
render expectation in controller spec.I used the following ways
render ''/channels/createchannel.html.erb''
view.should_receive(:render).with(:action => "createchannel")
ChannelsController.expect_render(:action => "createchannel")
ChannelsController.render_template(:action => "createchannel")
controller.expect_render(:action => "createchannel")
controller.render_template(:action => "createchannel")

All fail giving a NoMethodError

**********************************************************************************
My spec is as follows

require File.dirname(__FILE__) + ''/../spec_helper''

describe ChannelsController do
  it "should re-direct to create channel" do
    Channel.stub!(:checkChannel?).and_return(1)
    ChannelsController.expect_render(:action => "createchannel")

    #view.should_receive(:render).with(:action => "createchannel")
    #render ''/channels/createchannel.html.erb''
  end


end
**********************************************************************************


Can anyone please let me know how this can be fixed.?


Thanks & Regards
Chandrika

Check out http://rspec.info/rails/writing/controllers.html
Basically you need to do a get or post (in your case probably
post :createchannel) and then there''s a response object you can have
expectations on, such as response.should
render_template(''createchannel.html'').

Note, I''m not really sure what the
ChannelsController.expect_render(...) does, I''m unfamiliar with that
syntax.

Thanks,
\Peter

One good way to see how to write controller specs is to generate one with
script/generate (or rails generate if you''re using Rails 3).  For
example, you could create a new rails app (or use your existing one), and
generate an rspec_scaffold.  Something like this:

rails generate rspec_scaffold Widget name:string

.. that will generate a controller spec that will work out of the box if you are
using default crud methods.
