+Feature: Supports the timeout option
+  In order to handle inappropriately slow response times
+  As a developer
+  I want my request to raise an exception after my specified timeout as elapsed
+
+  Scenario: A long running response
+    Given a remote service that returns '<h1>Some HTML</h1>'
+    And that service is accessed at the path '/service.html'
+    And that service takes 2 seconds to generate a response
+    When I set my HTTParty timeout option to 1
+    And I call HTTParty#get with '/service.html'
+    Then it should raise a Timeout::Error exception
