如何在RouteUpdate导航防护之前测试Vue路由器? [英] How to test vue router beforeRouteUpdate navigation guard?

问题描述

首先，我正在使用Vue-property-decorator. 我的组件具有这样定义的组件路由.

First off, I'm using Vue-property-decorator. My component has a component route, defined like this.

@Component({
  components: {
    ComponentA,
    ComponentB
  },
  beforeRouteUpdate (to, _from, next) {
    const { checkInDate, checkOutDate, items, currency, locale } = to.query;
    const queryFullfilled = !!checkInDate && !!checkOutDate && !!items.length && !!currency && !!locale;

    if ([BOOKING_PAGE, RESERVATION_PAGE].indexOf(to.name) > -1 && queryFullfilled) {
      this.validateRooms();
    }
    next();
  }
})
export default class Layout extends Vue {}

为了涵盖beforeRouteUpdate中发生的事情，我需要怎么做?我已经用谷歌搜索了，人们指的是呼叫wrapper.vm.$options.beforeRouteUpdate.call() ...对我不起作用.

What do I need to do in my specs in order to cover what goes on in beforeRouteUpdate? I've googled this and people are pointing calling wrapper.vm.$options.beforeRouteUpdate.call()... that didn't work for me.

有人做过吗?我可以看任何代码示例吗?

Has anyone done this before? Any code samples I can look at?

先谢谢了. 约翰.

推荐答案

如果仍在寻找答案的人可以使用以下代码.

If anyone still looking for an answer following code will work.

const beforeRouteUpdate = wrapper.vm.$options.beforeRouteUpdate[0];
let nextFun = jest.fn();

// in place wrapper.vm you can send any object you want bcz when we call beforeRouteUpdate it looses this context

beforeRouteUpdate.call(wrapper.vm , "toObj", "fromObj", nextFun);
