How to setup testing environment with Vue + Jest

[paulocuambe]

Hi guys.

I need some help setting up tests with Vue + Jest.
I've read the docs, on the vue test utils site and they never mention Vite, they assume that you are using the vue-cli.

I did not have success following their instructions because I got the follow error when running the tests:

TypeError: Cannot destructure property 'config' of 'undefined' as it is undefined.
at Object.getCacheKey (node_modules/vue-jest/lib/index.js:10:7)

Here is my package.json

{
  "version": "0.0.0",
  "scripts": {
    "dev": "vite",
    "build": "vue-tsc --noEmit && vite build",
    "serve": "vite preview",
    "test": "jest"
  },
  "dependencies": {
    "vue": "^3.0.5"
  },
  "devDependencies": {
    "@types/jest": "^26.0.23",
    "@vitejs/plugin-vue": "^1.2.3",
