Add to your spec_helper.rb to make your view spec render calls DRYer.

spec_helper.rb

# Lets you just say 'render' in a view spec.  The path is
# discovered from the describe block.

# This is here so you can config.include(RenderHelper) to use this feature.
module RenderHelper
  def self.included(mod)
    if mod.ancestors.include? Spec::Rails::Example::RailsExampleGroup
      Spec::Rails::Example::ViewExampleGroup.instance_eval do
        def inherited(subclass)
          super
          subclass.send :include, ViewExampleGroupRender
        end
      end
    end
  end
end

# This is where the magic happens.
module ViewExampleGroupRender
  attr_reader :view_path
  
  def initialize(defined_description, &implementation)
    super
    @view_path = (self.class.superclass.description_args || self.class.description_args)[0].to_s
  end
  
  def render(*args)
    if args.empty?
      super @view_path
    else
      super *args
    end
  end
