Unknown custom element: <router-link> when using `mount()`

[ArmorDarks]

Version

1.0.0-beta.25

Steps to reproduce

Component Test.js, which uses another component with router-link inside:

import Vue from 'vue'
import Component from 'vue-class-component'

const Card = Component(class Card extends Vue {
  render () {
    return <router-link to='test'>Test</router-link>
  }
})

export default {
  render () {
    return <Card />
  }
}

Given the following test:

// @flow
/* eslint-env jest */

import { mount, createLocalVue, RouterLinkStub } from '@vue/test-utils'
import VueRouter from 'vue-router'

import Test from './Offices'

const localVue = createLocalVue()
localVue.use(VueRouter)

describe('Test.js', () => {
  it('should render with a stub', () => expect(mount(Test , {
    localVue,
    stubs: { 'router-link': RouterLinkStub }
  }).element).toBeDefined())

  it('should render with the router', () => {

    expect(mount(Test , {
      localVue
    }).element).toBeDefined()
  })
})

What is expected?

In both test cases router-link in OfficeCard should be stubbed and tests should pass without errors.

What is actually happening?

Instead, the following error will be logged to the console for both cases:

[Vue warn]: Unknown custom element: <router-link> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

---

The issue is definitely related to the vue-class-component since the following code will pass without errors:

import Vue from 'vue'
import Component from 'vue-class-component'

const Card = {
  render () {
    return <router-link to='test'>Test</router-link>
  }
}

export default {
  render () {
    return <Card />
  }
}

I assume it is because it directly extends Vue which prevents test-utils from effectively stubbing underlying components.

@eddyerburgh Thanks, however, was it really fixed? I'm still observing the same issue when using vue-class-component

The fix will be included in the next beta release, which will before September 15

Is it fixed? ???

I'm experiencing the same here:

describe('VHome', () => {
  const wrapper = mount(VHome, {
    stubs: {
      RouterLink: RouterLinkStub,
    },
  })

  it(' - Renders a vue instance', () => {
    expect(shallowMount(VHome).isVueInstance()).toBe(true)
  })

  it(' - Home Has a link to Ships', () => {
    expect(wrapper.find(RouterLinkStub).props().to).toStrictEqual({
      name: 'ships',
    })
  })
})

However if I comment out the first it, it doesn't throw any errors
