CodeSandbox Test Suite

I’m using CodeSandbox to do my 25+5 clock using React and am not able to get the test suite to show up. I used CodeSandbox for another React project (Random Quote Machine) and there I was able to make the test suite.

Here is how I inserted the script element for the working test suite :

, and here is the link to the whole code:

For the one that does not have the test suite showing up:
here is the “zoomed in” code:

render() {
    return (
      <div id="main">
       <script src=""></script>
        <div id="break">...

and the link to the entire app:

Please let me know why my code is not showing the test suite in the clock app. Thanks

p.s. Why am I only allowed to put one embedded media item and two links in this post?

You can add the script to the HTML file in the public folder right before the closing body tag </body>. You may have to refresh the page.

Edit: It has to do with the trust level, which depends on how much you have used the forum.
