Testing HTTP Digest Authentication in Rails 3

test_http_digest_rails3_patch.rb

# Add this to test/test_helper.rb

# Allow http digest authentication in functional tests, based on https://gist.github.com/1282275
# Call authenticate_with_http_digest(user, realm, digest) or authenticate_with_http_digest(user, realm, password, false) before you perform a request
class ActionController::TestCase
  require 'digest/md5'
  
  def authenticate_with_http_digest(user, realm, password, password_is_ha1 = true)
    ActionController::Base.class_eval { include ActionController::Testing }
    
    @controller.instance_eval %Q(
      alias real_process_with_new_base_test process_with_new_base_test
      
      def process_with_new_base_test(request, response)
        credentials = {
          :uri => request.url,
          :realm => "#{realm}",
          :username => "#{user}",
          :nonce => ActionController::HttpAuthentication::Digest.nonce(request.env['action_dispatch.secret_token']),
          :opaque => ActionController::HttpAuthentication::Digest.opaque(request.env['action_dispatch.secret_token'])
        }
        request.env['HTTP_AUTHORIZATION'] = ActionController::HttpAuthentication::Digest.encode_credentials(request.request_method, credentials, "#{password}", #{password_is_ha1})
        
        real_process_with_new_base_test(request, response)
      end
    )
  end
end

Change arguments to accept the digest instead of the plain-text password by default

I just started getting an error message using this code snippet in my tests. Any ideas?

Here is the error:

NameError: undefined method `process_with_new_base_test' for class `AuthController`
