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: attr_encrypted_test.rb
    path of file: ./repos/gitlabhq/vendor/gems/attr_encrypted/test
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

# encoding: UTF-8
require_relative 'test_helper'

class SillyEncryptor
  def self.silly_encrypt(options)
   
    
  def test_should_encrypt_with_true_if
    @user = User.new
    assert_nil @user.encrypted_with_true_if
    @user.with_true_if = 'testing'
    refute_nil @user.encrypted_with_true_if
    encrypted = Encryptor.encrypt(:value => 'testing', :key => SECRET_KEY, :iv => @user.encrypted_with_true_if_iv.unpack("m").first, :salt => @user.encrypted_with_true_if_salt.unpack("m").first)
    assert_equal encrypted, @user.encrypted_with_true_if
  end
