单元测试以断言在脚本加载事件触发时布尔值已更改

Question

我有一个加载 ckeditor.js 的脚本，加载后它会禁用自动内联..

var script = window.document.createElement('script');
script.setAttribute('type', 'text/javascript');
script.setAttribute('src', 'ckeditor.js');
window.document.body.appendChild(script);
script.addEventListener('load', function() {
  CKEDITOR.disableAutoInline = true;
});

有什么方法可以 assert 在触发脚本的 load 事件处理程序后将 CKEDITOR.disableAutoInline 设置为 true？

it('should ensure disableAutoInline is set to true when the ckeditor.js file is loaded in the browser', function() {
  window.CKEDITOR = {
    disableAutoInline: false
  };
  var ckeditorjs = window.document.querySelectorAll('[src=\'/ckeditor.js\']');
  expect(ckeditorjs.length).to.equal(1);
});

Answer 1

需要在 script ..

上实际触发 load 事件

var ckeditorjs = window.document.querySelectorAll('[src=\'/ckeditor.js\']');
window.CKEDITOR = {
  disableAutoInline: null
};
var event = new Event('load');
ckeditorjs[0].dispatchEvent(event);
expect(window.CKEDITOR.disableAutoInline).to.equal(true);
