Not able to mock $root

[hilkisahil]

I'm using vue 3 and vue-test-utils v2 . I have a component which uses $root to listen events. When I try to test this component it fails by throwing error 'this.$root.$on' is not a function.
I have even tried using mounting options 'parentComponent' but not working.

const Parent = {
  data() {
    return {
      $on: jest.fn(),
    }
  }
}
const wrapper = shallowMount(TestComponent, {
  parentComponent: Parent
})

Hi @hilkisahil

If you are using vue v3.2.45, then yes there is a change in vue core that we have to work around in VTU
We already have the fix, and we are going to release it soon
