Question: Is there a way to use BootstrapVue with VTU2?

[fgsalomon]

Hi,

I've some projects that use BootstrapVue that I'd like to migrate to Vue 3. Using @vue/compat I can run these projects without issues but I couldn't find a way to migrate their tests to the new tools.

Initially I was using Vue Testing Library v5 (VTU1)

Describe the question

Is it possible to use VTU2 with Vue 2 plugins like BootstrapVue and @vue/compat?

To Reproduce
I've set a minimal repo here: https://github.com/fgsalomon/vue3-bootstrap-vue-issues

This repo contains a component TestBootstrap.vue that uses BootstrapVue components.
The component has a unit test with Vue Testing Library v7 (VTU2).

Expected behavior
The test runs successfully.

Currently yarn test:unit fails with the error when trying to install BootstrapVue plugin:

TypeError: Vue.extend is not a function

I suppose it should work, as @xanf wrote the compact mode for VTU and is one of the authors of BootstrapVue
But I have to admit I don't use it myself, so I can't really help.

So let's friendly ping @xanf here to have his opinion, bu you'll probably have more luck opening thiss issue on BootstrapVue directly.
