Jest Vue failing: SyntaxError: Unexpected token 'export'

Question

I have sucessfully setup Jest with Quasar and Vue and most of my tests work. The only test that is failing is this one because of the following error message

Jest encountered an unexpected token

This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

Here's what you can do:
 • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
 • If you need a custom transformation specify a "transform" option in your config.
 • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/en/configuration.html

  at Object.<anonymous> (src/mixins/auth.js:1:1)

I have already added the following in my jest config:

  transformIgnorePatterns: [
    '<rootDir>/node_modules/(?!quasar/lang)',
    '<rootDir>/node_modules/(?!capacitor-firebase-auth/)',
  ],

I also tried the following

  transformIgnorePatterns: [
    '<rootDir>/node_modules/(?!quasar/lang)',
    '<rootDir>/node_modules/(?!capacitor-firebase-auth/dist/esm/)',
  ],

But again without luck. Anything I might be missing?
