RSpec の Routing のテストの出力綺麗にするやつ

routing_matchers.rb

module RSpec::Rails::Matchers
  module RoutingMatchers
    class RouteToMatcher
      def description
        method, path = @actual.first
        expected = @expected.dup
        to = "#{expected.delete(:controller)}##{expected.delete(:action)}"
        str = "route #{method.upcase} \"#{path}\" to \"#{to}\""
        if expected.any?
          str << " with parameter #{expected.inspect}"
        end
        str
      end
    end
  end
end

これを spec/support/ 以下に放り込む
