📚 Description

Custom vue components, typically added through a nuxt plugin, are not available in the testing environment.

sample:

export default defineNuxtPlugin(nuxtApp => {
  nuxtApp.vueApp.component('font-awesome-icon', FontAwesomeIcon);
});

when running a test and mounting a component that uses <font-awesome-icon>:

[Vue warn]: Failed to resolve component: font-awesome-icon
