+Feature: Scripted provisioning of target environment
+    As a developer
+    I would like a scripted deployment
+    so that I can assume the deployment will work the same way everytime
+
+    Background:
+        Given I am sshed into the environment
+
+    Scenario: Is the rails application deployed into the correct directory?
+        When I run "ls -las /var/www/rails/"
+        Then I should see "Gemfile"
+    
+    Scenario Outline: Have all the required gems been installed?
+        When I run "gem list"
+        Then I should see "<gem>"
+        
+        Scenarios: Gems installed
+        | gem    |
+        | rails  |
+        | sqlite |
+            
+    Scenario: Is the Apache service running?
+        When I run "/sbin/chkconfig --list httpd"
+        Then I should see "3:on"
+        
+    Scenario: The application is up and running
+        When I run "/usr/bin/wget -qO- http://target.devopscloud.com"
+        Then I should see "Sample App"
+

+Feature: Scripted provisioning of target environment
+    As a developer
+    I would like a scripted installation of my target environment
+    so that I can assume the environment will be the same everytime and my deployments will be predictable
+
+    Background:
+        Given I am sshed into the environment
+
+    Scenario: Is Passenger installed?
+        When I run "gem list"
+        Then I should see "passenger"
+    
+    Scenario: Is the proper version of Ruby installed?
+        When I run "/usr/bin/ruby -v"
+        Then I should see "ruby 1.8.7"
+    
+    Scenario: Is the proper version of Apache installed?
+        When I run "/usr/sbin/httpd -v"
+        Then I should see "2.2.22"
+        
+    Scenario: Is the Apache service running?
+        When I run "/sbin/chkconfig --list httpd"
+        Then I should see "3:on"
+        
+    Scenario: Httpd conf should have passenger variables
+        When I scrape "/etc/httpd/conf/httpd.conf"
+        Then "PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.12" should be present 
+        
+    Scenario: Httpd conf should have a virtual host added
+        When I scrape "/etc/httpd/conf/httpd.conf"
+        Then "NameVirtualHost \*:80" should be present
