+Feature: Middleman New Extension CLI
+
+  Scenario: Create a new extension scaffold
+    Given I run `middleman extension my-extension-library`
+    Then the exit status should be 0
+    When I cd to "my-extension-library"
+    Then the following files should exist:
+      | Gemfile                                       |
+      | Rakefile                                      |
+      | my-extension-library.gemspec                  |
