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…

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!

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://

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.
