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_bundled_ca.rb
    path of file: ./repos/ruby-packer/ruby/test/rubygems
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require 'rubygems/test_case'
require 'net/https'
require 'rubygems
    
    def bundled_certificate_store
      store = OpenSSL::X509::Store.new

      ssl_cert_glob =
        File.expand_path '../../../lib/rubygems/ssl_certs/*/*.pem', THIS_FILE

      Dir[ssl_cert_glob].each do |ssl_cert|
        store.add_file ssl_cert
      end

      store
    end
