Question

我正在使用一些浏览器测试来测试我的meteor应用程序的UI。我使用http://webdriver.io和selenium chrome https://hub.docker.com/r/selenium/standalone-chrome/节点。

我使用webdriver.io testrunner进行测试，使用mocha作为测试框架。

当我在玉石模板中输入此块时（通过打开相应的页面）：

Template.boardBody.onRendered(function() {

  let imagePath = new ReactiveVar('');

  this.autorun(() => {
    imagePath.set(Meteor.settings.public.backgroundPath[1]);
    //document.getElementsByClassName('board-wrapper')[0].style.backgroundImage = "url('" + imagePath.get() + "')";
    $('.board-wrapper').css('background-image', "url('" + path + "')");
  });
}

无头镀铬因此错误而崩溃：

我使用chai.expect作为我的断言陈述，我觉得这些承诺在某种程度上弄乱了无头的铬。

任何人都知道为什么会这样？
