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_rdoc_constant.rb
    path of file: ./repos/ruby-packer/ruby/test/rdoc
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require File.expand_path '../xref_test_case', __FILE__

class TestRDocConstant < XrefTestCase

  def setup
    super

    @const = @c1.constants.first
  end

  def test_documented_eh
    top_level = @store.add_file 'f
    
  def test_documented_eh_alias
    top_level = @store.add_file 'file.rb'

    const = RDoc::Constant.new 'CONST', nil, nil
    top_level.add_constant const

    refute const.documented?

    const.is_alias_for = 'C1'

    refute const.documented?

    @c1.add_comment comment('comment'), @top_level

    assert const.documented?
  end
