page_title = page_content.page_title
#O ...

page_group = PageGroup.create
page1 = page_group.pages.create

render :xml => page.to_xml(:only => [ :id, :scenario_id, :title], :include=> :pag ...

Everytime I want to make sure all functions work, I need to make a test model outside gem and test there.
