isolation_from_views.feature

Feature: views are stubbed by default

  By default, controller specs stub views with a template that renders an empty
  string instead of the views in the app. This allows you specify which view
  template an action should try to render regardless of whether the template
  compiles cleanly.

  NOTE: unlike rspec-rails-1.x, the real template must exist.
