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: class_spec.rb
    path of file: ./repos/yard/spec/templates
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require File.dirname(__FILE__) + '/spec_helper'

RSpec.describe YARD::Templates::Engine.template(:default, :docstring) do
  before do
    Registry.clear
    YARD.parse_string <<-'eof'
      private
      # Comments
      # @abstract 
    
        def method_missing(*args) end
        # @deprecated
        def a; end

        # constructor method!
        def initialize(test) end
      end

      class C < A; end

      class D
        # @private
        def initialize; end
      end
    eof
  end

  it "renders html format correctly" do
    html_equals(Registry.at('A').format(html_options), :class001)
  end

  it "renders text format correctly" do
    text_equals(Registry.at('A').format, :class001)
  end

  it "hides private constructors" do
    html_equals(Registry.at('D').format(html_options(:verifier => Verifier.new("!@private"))), :class002)
