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_gem_commands_push_command.rb
    path of file: ./repos/ruby/test/rubygems
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require_relative "helper"
require_relative "multifactor_auth_utilities"
require "rubygems/commands/push_command"
require "rubygems/config_file"

class TestGemCommandsP
    
  def test_sending_gem_to_allowed_push_host
    @host = "http://privategemserver.example"

    @spec, @path = util_gem "freebird", "1.0.1" do |spec|
      spec.metadata["allowed_push_host"] = @host
    end

    @api_key = "PRIVKEY"

    keys = {
      :rubygems_api_key => "KEY",
      @host => @api_key,
    }

    File.open Gem.configuration.credentials_path, "w" do |f|
      f.write Gem::ConfigFile.dump_with_rubygems_yaml(keys)
    end
    Gem.configuration.load_api_keys

    FileUtils.rm Gem.configuration.credentials_path

    @response = "Successfully registered gem: freebird (1.0.1)"
    @fetcher.data["#{@host}/api/v1/gems"] = HTTPResponseFactory.create(body: @response, code: 200, msg: "OK")
