# Reusable mocking of ActiveResource
#
# I use this technique when I need to mock ActiveResource in several tests and it gets a bit too keyboard
# heavy to use the default mechanism.

# Shortcut for typing ActiveResource::HttpMock.respond_to
def ar_mock(&block)
  ActiveResource::HttpMock.respond_to(&block)
end

module ActiveResource
  class HttpMock
    class Responder
      
      # Mocks create and get for a remote user object.
      def user(user_hash)
        post "/users.xml", request_headers, 
            user_hash.to_xml(:root => "user"), 200, {
              'Location' => "http://0.0.0.0:3000/users/#{user_hash[:id]}"
            }
        get "/users/#{id}.xml", request_headers, 
            user_hash[:id]
      end
    end
  end
end

# Actually using it:
ar_mock do |mock|
  mock.user({ :username => "alan", :password => "supersecret", :id => 1 })
end
