错误测试反应组件 - SecurityError

Question

我正在测试一个反应HOC,它会检查localstorage中是否存在令牌.如果有,则将用户重定向到Home组件,否则用户将被重定向到Login组件.

但是,我在最后一个测试调用componentDidMount的测试中遇到了这个奇怪的错误

引发SecurityError

在HistoryImpl._sharedPushAndReplaceState(node_modules/jsdom/lib/jsdom/living/window/History-impl.js:87:15)

在HistoryImpl.pushState(node_modules/jsdom/lib/jsdom/living/window/History-impl.js:69:10)

在History.pushState(node_modules/jsdom/lib/jsdom/living/generated/History.js:72:31)

这是我写的测试:

app.test.js

import React from 'react'; 
import { shallow, mount } from 'enzyme';
import { expect } from 'chai';
import sinon from 'sinon';

import App from '../containers/App.jsx';

describe('<App />', () => {
  beforeAll(() => {
    global.localStorage = {
      i2x_token: 'someToken',
      getItem() {
        return 'someToken';
      }
    };
  });

  it('renders without exploding', () => {
    shallow(<App />);
  });

  it('renders children when passed in', () => {
    const wrapper = shallow(
      <App>
        <div className='unique' />
      </App>,
   );
    expect(wrapper.contains(<div className='unique' />)).to.equal(true);
  });

 it('calls componentDidMount', () => {
    sinon.spy(App.prototype, 'componentDidMount');
    const wrapper = mount(<App />);
    expect(App.prototype.componentDidMount).to.have.property('callCount', 1);
    App.prototype.componentDidMount.restore();
  });
});

`

这是组件本身:

app.jsx

import React, { Component } from 'react';
import { browserHistory } from 'react-router';

class App extends Component {
  componentDidMount() {
    if (localStorage.i2x_token) {
       browserHistory.push('/home');
    } else {
      browserHistory.push('/');
    }
  }

  render() {
    return (
      <main>
        {React.Children.toArray(this.props.children)}
      </main>
    );
  }
}

App.propTypes = {
  children: React.PropTypes.node,
};

export default App;

这是我的package.json:

的package.json

  "dependencies": {
    "express": "^4.15.2",
    "react": "^15.4.2",

    "style-loader": "^0.16.1",
    "webpack": "^2.2.1",
    "webpack-dev-server": "^2.4.2"
  }

我想知道什么是错的.或许做反应路由器？

尝试testURL在Jest配置中进行设置.
