I am running a very very simply jest test suite at the moment,

import { createLocalVue, mount, shallowMount } from '@vue/test-utils';

import ModalRefactored from '../ModalRefactored.vue';

const localVue = createLocalVue();

describe('ModalRefactored', () => {
    let wrapper;    

    test('it does something', () => {

    });
})

When I run yarn test:unit I get the following error,

TypeError: Jest: a transform must export a process function.

My jest.config.js looks like this,

module.exports = {
  verbose: true,
  moduleFileExtensions: [
      "js",
      "json",
      "vue"
  ],
  transform: {
      ".*\\.(vue)$": "vue-jest",
      "^.+\\.js$": "<rootDir>/node_modules/babel-jest"
  },
  collectCoverage: true,
  collectCoverageFrom: [
      "src/components/**/*.{js,vue}",
      "!**/node_modules/**"
  ],
  coverageReporters: [
      "html",
      "text-summary"
  ],
}

I have absolutely no idea why I can't run my tests or what I am missing.
