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 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 componentTestBootstrap.vue that uses BootstrapVue components.
The component has a unittest with Vue Testing Library v7 (VTU2).

Expected behavior
The test runs successfully.

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

TypeError: Vue.extend is not a function
