You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: state_collection_with_event_transitions_test.rb
    path of file: ./repos/state_machines/test/unit/state_collection
    
    the code of the file until where you have to start completion: require 'test_helper'

class StateCollectionWithEventTransitionsTest < StateMachinesTest
  def setu
    
  def test_should_order_states_before_states_with_behaviors
    @parked.context do
      def speed
        0
      end
    end
    assert_equal [@idling, @parked], @states.by_priority
  end
