haml rspec missing template
===

This really caught me unguarded. The stocks/index.html.haml renders without problem in browser after I installed the haml-rails gem. However, when I tried to test it using rspec/capybara 

    describe "StockPages" do
      describe "stocks/index.html.haml" do
        before {visit stocks_path}
        subject {page}
        it { should have_selector('table#Result')  }
      end
    end

I got this error:

    Failure/Error: before {visit stocks_path}
         ActionView::MissingTemplate:
           Missing template stocks/index, application/index with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee]}.

How do I solve this?
Thanks
