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_variable.rb
    path of file: ./repos/ruby/test/ruby
    
    the code of the file until where you have to start completion: # frozen_string_literal: false
require 'test/unit'

class TestVariable < Test::Unit::T
    
  def test_cloned_allows_setting_cvar
    Zeus.class_variable_set(:@@rule, "Athena")

    god = Gods.new.ruler0
    zeus = Zeus.new.ruler0

    assert_equal "Cronus", god
    assert_equal "Athena", zeus
    assert_not_equal god.object_id, zeus.object_id
  end
