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: versions_controller_test.rb
    path of file: ./repos/mushroom-observer/test/controllers/names/descriptions
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require("test_helper")

module Names::Descriptions
  class VersionsController
    
    def test_show_past_name_description
      login("dick")
      desc = name_descriptions(:peltigera_desc)
      old_versions = desc.versions.length
      desc.update(gen_desc: "something new which refers to _P. aphthosa_")
      desc.reload
      new_versions = desc.versions.length
      assert(new_versions > old_versions)
      get(:show, params: { id: desc.id })
      assert_template("names/descriptions/versions/show")
      assert_template("descriptions/_show_description_details")
    end
