Hello kartik,

You must specify what environment (--env) are you going to use.

When you run jest command in the package.json you should specify the environment (jsdom or node). For example:

  "scripts": {
    "jest": "jest --env=node --colors --coverage test",
    "test": "npm run jest"
  },

This should work for you!
