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: quality_es_spec.rb
    path of file: ./repos/bundler/spec
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

RSpec.describe "La biblioteca si misma" do
  def check_for_expendable_words(filename)
    failing_line_message = []
    useless_words = %w[

      failing_line_message << "#{filename}:#{number.succ} contiene '#{word_found}'. Esta palabra tiene un significado subjetivo y es mejor obviarla en textos técnicos."
