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_spell_checker.rb
    path of file: ./repos/jruby/test/mri/did_you_mean
    
    the code of the file until where you have to start completion: require_relative './helper'

class SpellCheckerTest < Test::Unit::TestCase
  def test_spell_checker_corrects_mistypes
    
    
  def test_spell_checker_sorts_results_by_simiarity
    expected = %w(
      name12345
      name1234
      name123
    )

    actual = DidYouMean::SpellChecker.new(dictionary: %w(
      name12
      name123
      name1234
      name12345
      name123456
    )).correct('name123456')

    assert_equal expected, actual
  end
