# Use this module to easily test Alchemy actions within Alchemy components
# or inside your application to test routes for the mounted Alchemy engine.
#
# Inside your spec_helper.rb, include this module inside the RSpec.configure
# block by doing this:
#
#   require 'alchemy/test_support/controller_requests'
#   RSpec.configure do |c|
#     c.include Alchemy::TestSupport::ControllerRequests, type: :controller
#   end
#
# Then, in your controller tests, you can access alchemy routes like this:
#
#   require 'spec_helper'
#
#   describe Alchemy::Admin::PagesController do
#     it "can see all the pages" do
#       alchemy_get :index
#     end
#   end
#
# Use alchemy_get, alchemy_post, alchemy_put or alchemy_delete to make requests
# to the Alchemy engine, and use regular get, post, put or delete to make
# requests to your application.
#
# Note: Based on Spree::TestingSupport::ControllerRequests. Thanks <3
