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: event_with_transition_without_to_state_test.rb
    path of file: ./repos/state_machines/test/unit/event
    
    the code of the file until where you have to start completion: require 'test_helper'

class EventWithTransitionWithoutToStateTest < StateMachinesTe
    
  def test_should_have_a_transition
    transition = @event.transition_for(@object)
    refute_nil transition
    assert_equal 'parked', transition.from
    assert_equal 'parked', transition.to
    assert_equal :park, transition.event
  end
