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: actor_stress_test.rb
    path of file: ./repos/concurrent-ruby/examples
    
    the code of the file until where you have to start completion: #!/usr/bin
    
  def run
    plural = ->(number){ number == 1 ? '' : 's' }

    puts "Running #{@tests} test#{plural.call(@tests)} " +
      "with #{@threads} thread#{plural.call(@threads)} each " +
      "and #{@loops} loop#{plural.call(@loops)} per thread..."

    Benchmark.bmbm do |bm|
      @tests.times do
        bm.report do
          test(@threads, @loops)
        end
      end
    end
  end
