DOM中必须存在“el”标头

Question

我使用grunt-contrib-jasmine进行Marionette测试。我的规格通过但是我收到了这个错误：＆＃39;错误：＆＃34; el＆＃34;标头必须存在于DOM＆＃39;在木偶来源。我无法追查问题

我的咕噜声配置是：

jasmine : {
      src : [
        'common/js/app.js',
        'common/js/model/*.js',
        'common/js/collection/*.js',
        'common/js/view/*.js',
        'common/js/route/route.js'
      ],
      options : {
        '--web-security' : false,
        '--local-to-remote-url-access' : true,
        '--ignore-ssl-errors' : true,
        specs : 'test/spec/*.js',
        vendor: [
          'bower_components/jquery-2.1.0.min/index.js',
          'bower_components/jasmine-jquery/lib/jasmine-jquery.js',
          'bower_components/sinonjs/sinon.js',
          'bower_components/jasmine-sinon/lib/jasmine-sinon.js',
          'bower_components/underscore/underscore.js',
          'bower_components/bootstrap/dist/js/bootstrap.min.js',
          'bower_components/backbone/backbone.js',
          'bower_components/handlebars/handlebars.js',
          'bower_components/marionette/lib/backbone.marionette.min.js'
        ],
        host:  'http://localhost:3000'
      }
