Testing routes and controller results

I'm trying to write a functional test that generates a route and then follows that route to the controller and confirms that the appropriate record is retrieved.

I'm getting some unexpected errors --- I know the route works in development mode -- and wondering if anyone has an idea of what's happening here. Thanks for any help you can offer.

Here's the test...

def test_show_title     @news=Article.find(1)     get date_url(:title=>"#{@news.srctitle}",                  :section=>"#{@news.section.name}",                  :year=>"#{@news.created_at.year}",                  :month=>"#{@news.created_at.month}",                  :day=>"#{@news.created_at.mday.to_s}")

  end

and the error...

test_show_title(ArticlesControllerTest): NoMethodError: You have a nil object when you didn't expect it!
