 Feature:Host a spring mvc web application
 
 Scenario: Request routing
-Given I have a spring mvc application context location of "mvc-dispatcher-servlet.xml"
+Given I host a spring mvc application with context location of "WEB-INF/mvc-dispatcher-servlet.xml"
 And the application will respond to get requests for the uri "/hello" 
-When I host the application
 And I GET "/hello"
 Then I recieve an HTTPResponse with a 200 code

-#Scenario: Invalid application context
-#Given I have a spring mvc application context location of ""
-#When I host the application
-#Then I receive an error message reporting that "" is an invalid application context
-
-#Scenario: Missing the supporting spring mvc classes from the runtime environment
-#Given I have a spring mvc application context location of "application-servlet.xml"
-#And the application will respond to get requests for the uri "/hello"
-#But I don't have Spring MVC's supporting classes on my classpath
-#When I host the application
-#Then I receive an error message reporting the classes that cannot be found
