def immediately_perform_single_step(journey, step_name)
  journey.save!
  journey.update!(next_step_name: step_name, next_step_to_be_performed_at: Time.current)
  journey.perform_next_step!
end

#speedrun_journey(journey) ⇒ Object

Allows running a given Journey to completion, skipping across the waiting periods. This is useful to evaluate all side effects of a Journey. The helper will ensure that the number of steps performed is equal to the number of steps defined - this way it will not enter into an endless loop. If, after completing all the steps, the journey has neither canceled nor finished, an exception will be raised.

Parameters:

Returns:

  • void
