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_case.rb
    path of file: ./repos/powerstation/powerstation/lib/compiled-jruby/lib/ruby/stdlib/rubygems
    
    the code of the file until where you have to start completion: # TODO: $SAFE = 1

begin
  gem 'minitest', '~> 4.0'
rescue NoMethodError, Gem::LoadError
  # for
    
  def teardown
    $LOAD_PATH.replace @orig_LOAD_PATH if @orig_LOAD_PATH

    if @orig_BASERUBY
      RbConfig::CONFIG['BASERUBY'] = @orig_BASERUBY
    else
      RbConfig::CONFIG.delete('BASERUBY')
    end
