使用 Vue.js 和 Jest 进行 URL 重定向测试

我正试图编写一个测试来判断当用户点击"登录"按钮时，URL是否被重定向到/auth/.前端是用Vue编写的.js和测试是用Jest完成的.

以下是Vue组件如何重定向(从UserLogged.vue开始).它在浏览器中工作.

export default {
  name: 'UserLogged',
  props: ['userName'],
  methods: {
    login: function (event) {
      window.location.href = '/auth/'
    }
  }
}

下面是测试它的try :

import Vue from 'vue'
import UserLogged from '@/components/UserLogged'

describe('UserLogged.vue', () => {
  it('should redirect anonymous users to /auth/ when clicking on login button', () => {
    const Constructor = Vue.extend(UserLogged)
    const vm = new Constructor().$mount()
    const button = vm.$el.querySelector('button')
    // Simulate click event
    // Note: the component won't be listening for any events, so we need to manually run the watcher.
    const clickEvent = new window.Event('click')
    button.dispatchEvent(clickEvent)
    vm._watcher.run()
    expect(window.location.href).toEqual('http://testserver/auth/')
  })
})

测试输出给出"http://testserver/"而不是预期的"http://testserver/auth".
