Как загрузить двоичный файл во время модульного теста javascript?

Я использую grunt для построения своего проекта и запуска модульных тестов. Ниже-мой grunt.js, testacular.conf.js, и тест (javaclassstreamreader.spec.js). Короче говоря, grunt запускает grunt-server, который настроен для обслуживания двоичных файлов данных. Testacular настроен на прокси-сервер grunt-server. В тесте XMLHttpRequest используется для извлечения двоичного файла. Все работает, но кажется немного сложным. Есть ли более простой способ?

/*global module:false*/
module.exports = function(grunt) {"use strict";

  grunt.initConfig({
    pkg : '<json:package.json>',
    meta : {
      banner : '/*! <%= pkg.title || pkg.name %> - v<%= pkg.version %> - ' + '<%= grunt.template.today("yyyy-mm-dd") %>\n' + '<%= pkg.homepage ? "* " + pkg.homepage + "\n" : "" %>' + '* Copyright (c) <%= grunt.template.today("yyyy") %> <%= pkg.author.name %>;' + ' Licensed <%= _.pluck(pkg.licenses, "type").join(", ") %> */'
    },
