Testing project

There is the little test thingy that can check if you did you project right or if some stuff are missing, in some of my html/css projects I am seeing and able to use it but in some of them no matter what I tried I am unable to find it and cannot use it. please help me

Welcome, xshinigamix.

If you are referring to this:

It is called the Test Suite.

You need to paste the CDN link in your code pen:
<script src="https://cdn.freecodecamp.org/testable-projects-fcc/v1/bundle.js"></script>

Hope this helps

Thank you :slight_smile:
