+Feature: Undo
+  Because I am human and make mistakes
+  An admin
+  Should be able to undo actions they make
+
+  Scenario: delete a comment, then undo it
+    Given I am logged in
+    And the following comment exists:
+      | body              |
+      | Accidental Delete |
+    When I go to /admin
+    And I follow "Comments"
+    And I press "Delete Comment"
+    And I follow "Actions"
+    And I press "Undo"
+    Then a comment exists with attributes:
+      | body              |
+      | Accidental Delete |
