When I want to run my project with the command npm run test, I get the error below. What is causing this?

    To solve the Jest SecurityError: localStorage error you need to add the jest: { ... } part to your package.json file

    {

"name": "...",
"version": "..",
"main": "..",
"description": "...",
...

"jest": { "verbose": true, "testURL": "http://localhost/" },

}

    I just had this cropping up in a large monorepo (in unit tests, that otherwise wouldn't have required jsdom). Explicitly setting the following in our jest.config.js (or the package.json equivalent) also alleviated that issue:

    module.exports = {
  testEnvironment: 'node'
}

    Update: As Nicolas mentioned below (thanks!), you can also add the following flags if you're not using any config files:

    jest --testEnvironment node    
# or 
jest --env=node

    for me this was solved by upgrading to "jest": "^24.9.0",

    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!

    If you are using jsdom you have to change your setup for tests like this:

    const { JSDOM } = require('jsdom');
const jsdom = new JSDOM('<!doctype html><html><body></body></html>', {
  url: 'http://localhost/',
});```

    The suggestion in the top-rated answer of adding testURL: "http://localhost" to my Jest config didn't work for me. However, this suggestion from the jsdom GitHub discussion, of passing a URL in when creating the jsdom object, did.

    const url = 'http://localhost';

const dom = new JSDOM('<!DOCTYPE html><html><body></body></html>', { url });
