rspec users - Apr 2008 - Testing Layout

Is there a way to specify which layout an action should use in a
controller?

Off the top of my head, not tested:

describe MyController do
   it "should use the foo layout" do
     MyController.should_receive(:layout).with("foo")
     load("app/controllers/my_controller")
   end
end

but I''m sure there''s a more BDD way to do it (TIMTOWTDI goes
BDDWTDI ?).

Tried it. No dice it seems

So I then tried:

  it "should use the admin layout" do
    controller.should_receive(:layout).with("admin")
  end

And I get...

1)
Spec::Mocks::MockExpectationError in ''Admin::ProductsController should 
use the admin layout''
Mock ''Admin::ProductsController'' expected :layout with
("admin") once,
but received it 0 times

I''m not doing the load ... command you suggested. What is the thinking 
behind that? I''m finding that testing using RSpec demands you
understand
a lot more of what is going on inside the framework!

Cheers

That kind of makes sense, since should_receive''s should be defined  
*before* something happens. So, slightly diverting here, but say a  
Post should receive find(:all) when you go to index/, it would look  
something like:

describe PostsController do
   it "should find all posts" do
     Post.should_receive(:find).with(:all)
     get "index"
   end
end

The "trick" I gave you above was based on this one: http:// 
www.nabble.com/Testing-that-a-model-helper-method-is-called- 
td15856651.html

Perhaps you should try giving the full path to load, eg. load 
(RAILS_ROOT + "/app/controllers/my_controller.rb").

That seemed to do it... was perhaps a typo originally. My bad.

Thanks.
