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_minitest_benchmark.rb
    path of file: ./repos/ruby-packer/ruby/tool/test/minitest
    
    the code of the file until where you have to start completion: # encoding: utf-8
# frozen_string
    
  def test_cls_benchmark_methods
    assert_equal [], self.class.benchmark_methods

    c = Class.new(MiniTest::Unit::TestCase) do
      def bench_blah
      end
    end

    assert_equal ["bench_blah"], c.benchmark_methods
  end
