我有一个使用 Teleport to 的组件,测试 html 似乎没有按预期工作。我找不到有关此特定用途的任何文档。这是我的测试:
describe('MetaHead', () => {
it('dynamic metadata tags contain custom text', () => {
let title = 'My Page';
let description = 'Some description about my page';
// This component uses Vue3's teleport to tag <head>
// we must modify wrapper to contain such tag
document.body.innerHTML = `
<head>
<div id="app"></div>
</head>
`
const wrapper = mount(MetaHead, {
attachTo: document.getElementById('app'),
props: {
title,
description
},
global:{
mocks: {
$route:{fullPath: 'full/path'}
}
}
})
expect(wrapper.html()).toContain(title)
expect(wrapper.html()).toContain(description)
})
})
最小的组件如下所示:
<template>
<teleport to="head">
<title>{{title}}</title>
<meta property="og:site_name" :content="title">
<meta name="description" :content="description">
</teleport>
</template>
我错过了什么吗?
