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: leftover_distributor.rb
    path of file: ./repos/knapsack/lib/knapsack/distributors
    
    the code of the file until where you have to start completion: module Knapsack
  module Distributors
    class LeftoverDistributor < BaseDistributor
      def report_test
    
      def post_assign_test_files_to_node
        node_index = 0
        leftover_tests.each do |test_file|
          node_tests[node_index] << test_file
          node_index += 1
          node_index %= ci_node_total
        end
      end
