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

class CountryTest < ActiveSupport::TestCase
  def test_gb
    gb = Count
    
  def test_au
    au = Country.find("AU")
    assert_not_nil au
    assert_equal "AU", au.code
    assert_in_delta(112.911057, au.min_lon)
    assert_in_delta(-10.062805, au.max_lat)
    assert_in_delta(153.639252, au.max_lon)
    assert_in_delta(-43.64397, au.min_lat)
  end
