+Feature: Restore to draft
+  As a CMS author
+  I want to restore archived version to draft
+
+  Background:
+    Given a "page" "Home"
+      And a "page" "MyPage"
+      And the "group" "EDITOR" has permissions "Access to 'Pages' section" and "Access to 'Archive' section"
+      And I am logged in as a member of "EDITOR" group
+      And I go to "/admin/pages"
+      And I should see "MyPage"
+      And I click on "MyPage" in the tree
+      And I press the "Publish" button
+      And I click "More options" in the "#ActionMenus" element
+      And I press the "Unpublish and archive" button, confirming the dialog
+
+  Scenario: I can restore archived version to draft
+    When I go to "/admin/archive"
+    Then I should see "MyPage" in the "#Form_EditForm" element
+    Then I click "MyPage" in the "#Form_EditForm" element
+    Then I press the "Restore to draft" button
+    Then I should see "Successfully restored the page" in the "#Form_EditForm" element
+    When I go to "/admin/pages"
+    And I should see "MyPage" in the ".cms-tree [data-pagetype='Page']:nth-of-type(2).status-addedtodraft" element
