I am trying to test for cookies in my request: 

  The 'spec_helper' 'description of cookies' should be set correctly '' request.cookies ['foo'] = 'bar' and end   
 but it will give me the  Undefined method returns 'cookies': NilClass . How do I fix it?   
 
 
  request  object will be zero inside you test case unless you have a method < Do not request to use any of the code> get ,  post ,  delete ,  put , etc. .  
 For example, if you get  root_path  before  request.cookies ['foo'] = 'bar'  then your code works Will do
