Javascript 使用mocha和jsdom进行React单元测试失败

我正在使用mocha和jsdom对React进行基本的单元测试

这是我的密码：

var React = require('react/addons'),
    assert = require('assert'),
    TodoItem = require('../app/components/todo-item.jsx'),
    TestUtils = React.addons.TestUtils;

describe('Todo-item component', function(){
  before('render and locate element', function() {
    var renderedComponent = TestUtils.renderIntoDocument(
      <TodoItem done={false} name="Write Tutorial"/>
    );

    // Searching for <input> tag within rendered React component
    // Throws an exception if not found
    var inputComponent = TestUtils.findRenderedDOMComponentWithTag(
      renderedComponent,
      'input'
    );

    this.inputElement = inputComponent.getDOMNode();
  });

  it('<input> should be of type "checkbox"', function() {
    assert(this.inputElement.getAttribute('type') === 'checkbox');
  });

  it('<input> should not be checked', function() {
    assert(this.inputElement.checked === false);
  });

我做错了什么。我正在努力学习教程。

我刚刚从链接教程中的package.json复制了这篇文章。试着像这样运行测试：

mochatest/***-test.js——编译器js:babel core/register——递归

这应该是注释，而不是答案：）这应该是注释，而不是答案：）

var React = require('react');

module.exports = React.createClass({
