How to write follow up action in rasa test stories

As mentioned in rasa docs: " [Custom Actions] are not executed as part of end-to-end tests. If your custom actions append any events to the tracker, this has to be reflected in your end-to-end tests (e.g. by adding slot events to your end-to-end story)."

For SetSlot event we write :

  • greet: hi
    • my_custom_action
    • slot{“my_slot”: “value added by custom action”}
    • utter_ask_age

What is the syntax to write FollowUp and Rewind events in rasa test stories?
