My hopes and dreams for error handling in Asp.net - defined in cukes

ErrorHandlingInAspnet.spec

Feature: Error handling in asp.net
  Errors occur in web apps and we need to be able to handle the exceptions (e.g. log them) and show customers appropriate messages in a meaning full and consistent manner.
  These test assume Accept:text/html or equivalent
  #RHYSC -I don't mind how the error information is surfaced but it should be accessible in a common and clean manner
  #these specs can be extrapolated out to the other error codes too
 
  Scenario: 404 on static files
    Given a static file ~/test.html does not exist
    When we navigating to ~/test.html 
    Then the on error event should be raised by XYZ with path information and 404 http status code
    And the 404 error page should be shown with a response code of 404
    And the URL path should be still be /Test/Fail
    
  Scenario: 404 on bad routes 
    Given a route /IDont/Exist is not defined 
    When we navigating to ~/IDont/Exist
    Then the on error event should be raised by XYZ with path information and 404 http status code
    And the 404 error page should be shown with a response code of 404
    And the URL path should be still be /Test/Fail
    
  Scenario: 404 on bad actions 
    Given a route /test/{action} is not defined 
     And the action Fail does not exist on TestController
    When we navigating to ~/Test/Fail
    Then the on error event should be raised by XYZ with path information and 404 http status code
    And the 404 error page should be shown with a response code of 404
    And the URL path should be still be /Test/Fail
    
  Scenario: Explicitly return a 404 result from application code
    Given a route /test/ok/{id} is defined 
     And the resource for id = 5 does not exist
    When we navigating to ~/Test/Ok/5
     and the action returns a HttpStatusCodeResult(HttpStatusCode.NotFound)
    Then the on error event should be raised by XYZ with path information and 404 http status code
    And the 404 error page should be shown with a response code of 404
    And the URL path should be still be /Test/Fail
