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: test_alias.rb
    path of file: ./repos/ruby-packer/ruby/test/ruby
    
    the code of the file until where you have to start completion: # frozen_string_literal: false
require 'test/unit'

class TestAlias < Test::Unit::TestCase
  class Alias0
    def foo
      "foo"
    en
    
  def test_alias_with_zsuper_method
    c = Class.new
    c.class_eval do
      def foo
        :ok
      end
      def bar
        :ng
      end
      private :foo
    end
    d = Class.new(c)
    d.class_eval do
      public :foo
      alias bar foo
    end
    assert_equal(:ok, d.new.bar)
  end
