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_normal_class.rb
    path of file: ./repos/ruby/test/rdoc
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
re
    
  def test_ancestors_multilevel
    c1 = @top_level.add_class RDoc::NormalClass, 'Outer'
    c2 = @top_level.add_class RDoc::NormalClass, 'Middle', c1.full_name
    c3 = @top_level.add_class RDoc::NormalClass, 'Inner', c2.full_name

    assert_equal [c2, c1, @object, 'BasicObject'], c3.ancestors
  end
