# Example:
#
# Let's say we're are accessing a new form to create a Post, probably
# our page will be rendered by PostsController and new action:
class PostsController < ApplicationController
  def new
    @post = Post.new

I was reading Practical Objected-Oriented Design With Ruby other day and Sandi Metz came up with a good and reasonable approach of how to deal with Roles (by role I mean Concerns and overall duck typing stuff) specs.

• The Role itself should be tested with a test's built-in player. Ex.:
