How to activate FCC test suite on codepen?

Tell us what’s happening:

Hi all,

Does anyone know how to activate the FCC test suite function on codepen? Is it available to any user of codepen regardless the membership status or you need to have a PRO account, to have access to this feature?

P.S: I want to test my FCC projects to check if they meet all the user stories.


Your code so far

Your browser information:

Link to the challenge:


Just add<script src=""></script> at the top of your html.
That’s it. :slight_smile:
No PRO account needed


It doesn’t work in javascript challenges. Is there any way I can do it in these challenges?

the javascript challenges are tested in the freecodecamp editor

you don’t need to code outside of freecodecamp for those
