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: application_helper_test.rb
    path of file: ./repos/openstreetmap-website/test/helpers
    
    the code of the file until where you have to start completion: require "test_helper"

class ApplicationHelperTest < ActionView::TestCase
  attr_accessor :current_user

  def test_linkify
    %w[http://example.com/test ftp://example.com/test https://example.com/test].each do |link|
      text = "Test #{link} is <b>made</b> into a link"

      html = linkify(text)
      assert_predicate html, :html_safe?
      assert_dom_equal "Test <a href=\"#{link}\" rel=\"nofollow\">#{link}</a> is &lt;b&gt;made&lt;/
    
  def test_friendly_date_ago
    date = friendly_date_ago(Time.utc(2014, 3, 5, 18, 58, 23))
    assert_match %r{^<time title=" *5 March 2014 at 18:58" datetime="2014-03-05T18:58:23Z">.*</time>$}, date

    date = friendly_date_ago(Time.now.utc - 1.hour)
    assert_match %r{^<time title=".*">about 1 hour ago</time>$}, date

    date = friendly_date_ago(Time.now.utc - 2.days)
    assert_match %r{^<time title=".*">2 days ago</time>$}, date

    date = friendly_date_ago(Time.now.utc - 3.weeks)
    assert_match %r{^<time title=".*">21 days ago</time>$}, date

    date = friendly_date_ago(Time.now.utc - 4.months)
    assert_match %r{^<time title=".*">4 months ago</time>$}, date
  end
