Cannot mock the global $route and $router since vue-router update to v2.8.0

Version

1.0.0-beta.13

Reproduction link

https://jsfiddle.net/getk99n0/

Steps to reproduce

1. Follow the tutorial (https://vue-test-utils.vuejs.org/en/guides/using-with-vue-router.html) to mock the $route

import { shallow } from '@vue/test-utils'

describe('test', () => {
  it('mock $route', () => {
    const $route = { path: '/some/path' }
    const wrapper = shallow(Sidebar, { mocks: { $route } }).vm
    console.log(wrapper.$route)
  })
})

1. run the test and got undefined

What is expected?

Should get correct mock $route/$router value

What is actually happening?

Get undefined from wrapper.$route and wrapper.$router

---

I can still get { path: ‘/some/path’ } as result when the version of the vue-router still in v2.7.0, sorry not sure if I should raise the issue here or in vue-router, can anyone help please 😦? thanks!

NOTE that I also get this error '[vue-test-utils]: could not overwrite property $route, this usually caused by a plugin that has added the property as a read-only value' but I didn’t use any VueRouter in my other test case includes current one.

Sorry, I gave you untested regex. You should update that line to this:

const srcContext = require.context('../../src/', true, /^(?!.*(?:assets|main|router)).*\.*$/)

VueRouter has been installed somewhere.

If you used Vue CLI webpack template to generate the project, the Vue Router is required before all karma tests—https://github.com/vuejs-templates/webpack/blob/develop/template/test/unit/index.js#L12

If not, make sure you aren’t importing a file in your test that imports another file that installs Vue Router.
