Vue scss style loads fails with mocamapck

Question

I'm having a problem when unit testing a vue single file component with some scss styling, as it is unable to process the @import statements. It works when I run launch the app using yarn run dev or build for production yarn run build, issue is only with unit test mode, and my setup uses mochapack to run the webpack before executing the test.

Any ideas on how may this be resolved. I don't need to load scss for testing, although I'm unable to disable style processing (null-loader) as I do not have a webpack.config file in the project, and I would not create one unless absolutely necessary. Project is generated with Vue CLI.

I was able to fix this by prefixing the path with '~@/...', give it a try and see. Example: "@import: '~@/styles/variables'; "
