Controller specs by default won't render any views, which means that the views are currently untested (which is why your tests didn't fail for articles#show when there was a little bug in the show.html.erb). You can tell controller specs to render views by plopping in a `integrate_views`, but it would probably be better to include some integration specs in addition to the controller specs. Have you read at all about integration specs? In a nutshell it's just walking through exactly what a user would do on the site (visiting a page, clicking a link, etc), and verifying that everything is behaving as expected in response to their interactions.
