Question

我正在尝试使用sinon测试localStorage。基本上我对单元测试很新，所以这可能是非常基础的。

更新

我设法提出了这个问题，但现在却给了我一个新的错误Should wrap property of object

测试

describe('Initial State', () => {
    it('should set the initial state for the component', () => {
const props = {
        currentUser: {}
      };
      sinon.stub(window.localStorage, 'setItem');
      window.localStorage.setItem('none', 'nothing');
    });
  });

您可以在所有测试中使用babel-plugin-rewire将mockStorage替换为模拟版本。

这就是我使用它的方式：

import {unauth, signOut, __RewireAPI__} from 'modules/auth/actions';

const rewrite = __RewireAPI__.__Rewire__;

const local = {}; // object where you store all values localStorage needs to return
const storage = {
  get(key) {
    return local[key];
  },
  set: sinon.spy(),
  remove: sinon.spy()
};

rewrite('storage', storage); // rewrite storage package with your mocked version

// in you test add values you want to get from localStorage
local.credentials = constants.CREDENTIALS;
local.authToken = constants.TOKEN;
