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_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 EventTest < StateMachinesTest
  def setup
    @machin
    
  def test_should_provide_matcher_helpers_during_initialization
    matchers = []

    @event.instance_eval do
      matchers = [all, any, same]
    end

    assert_equal [StateMachines::AllMatcher.instance, StateMachines::AllMatcher.instance, StateMachines::LoopbackMatcher.instance], matchers
  end
