+  Scenario: Delete post
+  # If this was a real API supported by a working data source I would make a GET request to the Posts endpoint after
+  # deleting the post to ensure that the total number of posts has decreased and that post 1 had been deleted
+    When I make a DELETE request to the Posts endpoint with a path parameter of 1

+  Scenario Outline: Delete post with invalid ID - post #<ID>
+  # As this is a fake API without an underlying data source that updates based on the API requests, a delete request
+  # returns a success response regardless of the post ID passed in via the path parameters. This should raise an error
+  # for a real API
