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: twilio_install_generator_tests.rb
    path of file: ./repos/boring_generators/test/generators
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require "test_helper"
require "generators/boring/twilio/install/install_ge
    
  def test_should_install_twilio_successfully
    Dir.chdir(app_path) do
      quietly { run_generator }

      assert_file "Gemfile" do |content|
        assert_match(/twilio-ruby/, content)
      end

      assert_file "config/initializers/twilio.rb"
    end
  end
