+  @regression @flow-status-history
+  Scenario: Creating a flow
+    Given a flow exists
+    Then the status of the flow is offline by default

+  Scenario: Updating a flow 
+    Given a flow exists
+    When the flow status is changed to online
+    Then the open flow_status_history record is updated
