When importing types in component, it fails in jest environment. To reproduce run:
npm run test
You should see an error:
[@vue/compiler-sfc] No fs option provided to `compileScript` in non-Node environment. File system access is required for resolving imported types.
See vue3JestHack.js file.
In jest.config.js uncomment the transform option to use vue3JestHack, and run test again. You should see tests passing
