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: generate_perf_testdata.rb
    path of file: ./repos/gitlabhq/qa/qa/tools
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
    
      def create_many_labels
        30.times do |i|
          create_a_label_api_req("#{@group_name}%2F#{@project_name}", "label#{i}", "#{Faker::Color.hex_color}")
        end
        @urls[:labels_page] = @urls[:project_page] + "/labels"
        $stdout.puts "Created many labels: #{@urls[:labels_page]}"
      end
