+Feature: Manage WordPress post revisions
+
+  Background:
+    Given a WP install
+
+  # Creating a published post doesn't create an initial revision,
+  # so we update it twice here and restore the middle version.
+  # See https://github.com/wp-cli/entity-command/issues/564.
+  Scenario: Restore a post revision
