rspec users - Aug 2008 - template.expect_render fails when partial is rendered from a helper

My spec;

  describe ''subnav rendering while logged in'' do

    before do
      template.stub!(:logged_in?).and_return(true)
      template.stub!
(:current_profile).at_least(:once).and_return(mock_profile)
    end

    def do_render
      render "/homepages/show.html.erb"
    end

    it "should render the logged in partial for homepages" do
      template.expect_render(:partial =>
''shared/subnav/home'', :locals
=> {:active => :home})
      do_render
    end

  end

passes if I render the partial directly in the view,

render :partial => ''shared/subnav/home'', :locals =>
{:active => :home}

but it fails if the partial is rendered by a helper;

module ApplicationHelper
  def subnav(partial, args={})
    active = args[:active] || :no_highlight
    if partial == :home
      partial = (logged_in? ? ''home'' :
''login'')
    end
    render :partial => "shared/subnav/#{partial}", :locals =>
{:active
=> active}
  end
end

Is there any way to check whether the helper renders it?

Is this expected behaviour?

If the code in the subnav method is resulting in what you are assuming
it is, this should work. I''d try putting exactly the same code (with
everything hard coded and no conditional logic) in the subnav method
and see if you get the same result. If you get an error, please copy
the error in your response.
