How to access cookies and session in Capybara 2.4.1

I am using 4 rails with the following gems:

• guard-rspec (4.3.1)
• rspec (3.0.0)
• rspec-core (3.0.3)
• rspec waits (3.0.3)
• rspec-mocks (3.0.3)
• rspec-rails (3.0.2)
• rspec-support (3.0.3)
• capybara (2.4.1)
• capybara-webkit (1.1.0)

Capybara works as expected in normal scripts / examples, but when I want to access a cookie or session, I get a NameError:

undefined local variable or method `session'

      

        
        
        
      

    

I have a custom class that I am using that stores cookie data and retrieves it to remember things about the user and then present certain things on the screen.

But I cannot get the tests to pass and I cannot view the cookie or session.

Do I need to mock? How can i do this?
