Mock Cookies in Rails Tests the Easy Way

I got really tired of mocking out cookies every single time I made a reference to cookies in my test. It looked like a bunch of spaghetti code that made me mock out every single cookie call that I could imagine. Don’t get me wrong, I think mocks are wonderful, but when you have to mock out every single call, I don’t think the pain is worth the gain. I found it much easier to mock cookies like this as like this, which gives a pretty good approximation of rails cookies. It won’t work for 100% of cookie testing cases, but for 99.9%, it works like a charm.

I use rspec to test, but you could easily port the Cookie class to any testing framework that you want.

def stub_cookies
  stub!(:cookies).and_return(MockCookie.new)
end

class MockCookie < Hash

  def [](name)
    super(name.to_s)
  end
 
  def []=(key, options)
    if options.is_a?(Hash)
      options.symbolize_keys!
    else
      options = { :value => options }
    end
    super(key.to_s, options[:value])
   end

  def delete(key,opts)
    super(key)
  end

end
