How to add the Test Suite in your code editor of choice

<script src="https://cdn.freecodecamp.org/testable-projects-fcc/v1/bundle.js"></script>

This script works no more on my Pen.
Is it a reason? Is something changed?

I have tested this on front end projects, and they don’t work in codepen, but work in local environment.

My guess is the issue with codepen.

I can open issue in github, but they are planning to move these projects, so you can do them in freeCodeCamp without external site help.

Thanks for the answer Sboony, but I’m still confused.

No worries

Is something changed?

Yes, freeCodeCamp is moving away from using external site like CodePen and replit, by replacing them with ways to do challenges online in fCC editors.

here is a link for new challenge:

Product Landing Page: Build a Product Landing Page | freeCodeCamp.org


This script works no more on my Pen.

I have installed this script in my GitHub repo, and it’s working fine while testing in http://localhost:3000/

So I think the issue is from CodePen itself, because the script works fine in my GitHub repositories


Is it a reason?

To be honest, I don’t know the specific reason for CodePen to act funny.

All I know that, you won’t need to use CodePen or Replit in the future, when you try to get certifications.


I hope that helps, I am happy to ask around if you need more info.

It helps. Now I understand what’s wrong with CodePen.
I haven’t been active in freeCodeCamp for a year and now I’m trying to get back.
So Replit is also useless for my Back End Development and APIs chapter.

Fortunately, not yet. We are currently focusing on moving the front-end projects.:+1:

So you can comfortably do backend projects, like before.
