test rails controllers that are not in spec/controllers with rspec 2

rspec expects your controller specs to be in /spec/controllers. I have some modules that are included in my controllers. The only way to test them, near as I can tell, is to create a dummy controller, include the module in it, and test from there. The problem is that the module specs are in /spec/lib/module, and so ControllerExampleGroup is not included, which means I can't call the helper methods get "action" etc.

I can manually import these, which gets me most of the way there, but I then get this error:

Suggestions?

If you have a spec that's not in one of the standard locations, you can always tell rspec by passing a :type attribute to the describe method:

describe MyController, :type => :controller do
    ...
end

For specing modules that are meant to be included by a controller, rspec 2 has a very handy way to create anonymous controllers.

describe MyModule do

    context "when included by a controller", :type => :controller do
        controller do      # anonymous subclass of ActionController::Base
            include MyModule

            def index
                head :ok
            end
        end

        it "works" do
          get "index"
          response.should be_success
        end
    end
end
