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_mechanize_http_auth_realm.rb
    path of file: ./repos/mechanize/test
    
    the code of the file until where you have to start completion: require 'mechanize/test_case'

class TestMechanizeHttpAuthRealm < Mechanize::TestCase

  def setup
    super

    @uri = URI 'http://example/'
  
    
  def test_equals2
    other = @realm.dup
    assert_equal @realm, other

    other = @AR.new 'Basic', @uri, 'r'
    refute_equal @realm, other

    other = @AR.new 'Digest', URI('http://other.example/'), 'r'
    refute_equal @realm, other

    other = @AR.new 'Digest', @uri, 'R'
    refute_equal @realm, other

    other = @AR.new 'Digest', @uri, 's'
    refute_equal @realm, other
  end
