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: test_irb.rb
    path of file: ./repos/irb/test/irb
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require "irb"

require_relative "helper"

module TestIRB
  class InputTest < IntegrationTestCase
    def test_symbol_aliases_are_handled_correctly
      write_ruby <<~'RUBY'
        class Foo
        end
        binding.irb
      RUBY

      output = run_ruby_file d
    
    def test_empty_input_echoing_behaviour
      write_ruby <<~'RUBY'
        binding.irb
      RUBY

      output = run_ruby_file do
        type ""
        type "  "
        type "exit"
      end

      # Input cramped together due to how Reline's Reline::GeneralIO works
      assert_include(
        output,
        "irb(main):001> irb(main):002> irb(main):002>  irb(main):002>   => nil\r\n"
      )
    end
