Testing Cookies in Ruby on Rails

Posted by Mon, 28 Aug 2006 12:27:00 GMT

Over the weekend, Brian Ford released a useful plugin for testing your Ruby on Rails applications called, assert_cookie.

Brian likes his cookies…

“I love cookies. There are, of course, tons of varieties and I’m no connoisseur but I love the soft chocolate chip right out of the oven, hot and gooey. But, if you’re like me, you don’t want your Rails code to be gooey.” -Brian Ford

To use assert_cookie, follow these steps.

  1. Install via, script/plugin install
  2. Fill your tests with some cookies
  3. Test your cookies!
Here are a few examples that Brian posted.
  assert_cookie :pass, 
      :value => lambda { |value| UUID.parse(value).valid? }
  assert_cookie :yellow, :value => ['sunny', 'days']
  assert_cookie :delight, :value => 'yum'
  assert_cookie :secret, :path => lambda { |path| path =~ /secret/ }, 
      :secure => true
