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.

Scenarios
  1. expect template that is rendered by controller action (passes)
  2. expect template that is not rendered by controller action (fails)
  3. expect empty templates to render when view path is changed at runtime (passes)
  4. expect template to render the real template with render_views when view path is changed at runtime
expect template that is rendered by controller action (passes)
Given
a file named "spec/controllers/widgets_controller_spec.rb" with: 
require "spec_helper"

describe WidgetsController do
  describe "index" do
    it "renders the index template" do
      get :index
      response.should render_template("index")
      response.body.should eq ""
    end
    it "renders the widgets/index template" do
      get :index
      response.should render_template("widgets/index")
      response.body.should eq ""
    end
  end
end
When
I run rspec spec
Then
the examples should all pass
expect template that is not rendered by controller action (fails)
Given
a file named "spec/controllers/widgets_controller_spec.rb" with: 
require "spec_helper"

describe WidgetsController do
  describe "index" do
    it "renders the 'new' template" do
      get :index
      response.should render_template("new")
    end
  end
end
When
I run rspec spec
Then
the output should contain "1 example, 1 failure"
expect empty templates to render when view path is changed at runtime (passes)
Given
