Hi @sanglnv, I'm unable to reproduce this. Which branch are you running your setup command on?

kentcdodds commented 4 years ago

I've made a few changes to the repo that should avoid this problem. Please let me know if you see it again.

I had the same problem when I just repeated @kentcdodds actions in the course and install Jest using command npm install --save-dev jest because it installs latest version of Jest. After I manually installed version 22.4.3 the problem was gone. But I had another one:

> jest

 FAIL  src\__tests__\utils.js
  ● Test suite failed to run

    SecurityError: localStorage is not available for opaque origins

      at Window.get localStorage [as localStorage] (node_modules/jsdom/lib/jsdom/browser/Window.js:257:15)
          at Array.forEach (<anonymous>)

This problem was solved by installing jest 23.6.0
