+Feature:  Basic Authentication
+
+  As a developer
+  I want to be able to use a service that requires Basic Authentication
+  Because that is not an uncommon requirement
+
+  Scenario: Passing no credentials to a page requiring Basic Authentication
+    Given a restricted page at '/protected.html'
+    When I call HTTParty#get with '/protected.html'
+    Then it should return a response with a 401 response code
+
+  Scenario: Passing proper credentials to a page requiring Basic Authentication
+    Given a remote service that returns 'Authenticated Page'
+    And that service is accessed at the path '/protected.html'
+    And that service is protected by Basic Authentication
+    And that service requires the username 'jcash' with the password 'maninblack'
+    When I call HTTParty#get with '/protected.html' and a basic_auth hash:
+       | username | password   |
+       | jcash    | maninblack |
+    Then the return value should match 'Authenticated Page'

+Feature: Command Line
+
+  As a developer
+  I want to be able to harness the power of HTTParty from the command line
+  Because that would make quick testing and debugging easy

+Feature: Deals with HTTP error codes
+
+  As a developer
+  I want to be informed of non-successful responses
+  Because sometimes thing explode
+  And I should probably know what happened
+
+  Scenario: A response of '404 - Not Found'
+    Given a remote service that returns a 404 status code
+    And that service is accessed at the path '/service.html'
+    When I call HTTParty#get with '/service.html'
+    Then it should return a response with a 404 response code

+    Given a remote service that returns a 500 status code
+    And that service is accessed at the path '/service.html'
+    When I call HTTParty#get with '/service.html'
+    Then it should return a response with a 500 response code
+
+  Scenario: A non-successful response where I need the body
+    Given a remote service that returns a 400 status code
+    And the response from the service has a body of 'Bad response'
+    And that service is accessed at the path '/service.html'
+    When I call HTTParty#get with '/service.html'
+    Then it should return a response with a 400 response code

@@ -0,0 +1,34 @@
+Feature: Handles Multiple Formats
+
+  As a developer
+  I want to be able to consume remote services of many different formats
+  And I want those formats to be automatically detected and handled
+  Because web services take many forms
+  And I don't want to have to do any extra work
+
+  Scenario: An HTML service
+    Given a remote service that returns '<h1>Some HTML</h1>'
+    And that service is accessed at the path '/service.html'
+    And the response from the service has a Content-Type of 'text/html'

+    Then it should return a String
+    And the return value should match '<h1>Some HTML</h1>'
+
+  Scenario: A JSON service
+    Given a remote service that returns '{ "jennings": "waylon", "cash": "johnny" }'
+    And that service is accessed at the path '/service.json'
+    And the response from the service has a Content-Type of 'application/json'
+    When I call HTTParty#get with '/service.json'
+    Then it should return a Hash equaling:
+       | key      | value  |
+       | jennings | waylon |
+       | cash     | johnny |

+    And the response from the service has a Content-Type of 'text/xml'

+Feature: Supports Redirection
+
+  As a developer
+  I want to work with services that may redirect me
+  And I want it to follow a reasonable number of redirects
+  Because sometimes web services do that
+
+  Scenario: A service that redirects once
+    Given a remote service that returns 'Service Response'
+    And that service is accessed at the path '/service.html'
+    And the url '/redirector.html' redirects to '/service.html'
+    When I call HTTParty#get with '/redirector.html'
+    Then the return value should match 'Service Response'
+
+  # TODO: Look in to why this actually fails...
+  Scenario: A service that redirects to a relative URL
+
+  Scenario: A service that redirects infinitely
+    Given the url '/first.html' redirects to '/second.html'
+    And the url '/second.html' redirects to '/first.html'
+    When I call HTTParty#get with '/first.html'
+    Then it should raise an HTTParty::RedirectionTooDeep exception
