reactjs - Jest 测试,sessionStorage 未定义

我正在尝试运行我的第一个 Jest 测试,但出现此错误

 FAIL  src\containers\__test__\AppContainer.spec.js
● Test suite failed to run

ReferenceError: sessionStorage is not defined

我不确定我是否应该得到这个错误,因为我没有测试 sessionStorage,只是想测试根容器。

--更新--

import React from 'react'
import { shallow } from 'enzyme'
import AppContainer from '../AppContainer'

//Tried here also
global.sessionStorage = {
data: {},
setItem: (key, value) => {
this.data[key] = value
},
getItem: (key) => this.data[key]
}
describe('AppContainer', () => {
beforeEach(function () {
global.sessionStorage = {
data: {},
setItem: (key, value) => {
this.data[key] = value
},
getItem: (key) => this.data[key]
}
})

it('should render self and subcomponents', () => {
const enzymeWrapper = shallow(<AppContainer />)

expect(enzymeWrapper.find('div').hasClass('grommetux-app')).toBe(true)
})
})

我正在通过库“使用”sessionStorage,oidc-clientjs ,所以我真的无法控制它。

错误来源的第23行是

import { createUserManager } from 'redux-oidc'
....
const userManager = createUserManager(config) (L23)

最佳答案

我正在使用 Create-react-app,所以我将它添加到 src/setupTests.js

const sessionStorageMock = {
getItem: jest.fn(),
setItem: jest.fn(),
clear: jest.fn()
};
global.sessionStorage = sessionStorageMock;
