Can someone confirm that the testing for the beta projects currently isn’t working? Once confirmed I’ll flag the issue on GH.
When I try to run one for the Codepen’s using the script, I get this in the console:
Hmmm…problem must be on my end then.
I think my workplace might have just fiddled with our proxy settings. It was working fine a couple of days ago 
I have a work around, just in case anyone faces a similar issue.
The CDN hosted version of the testing suite doesn’t work for me, but the version hosted on github does.
Anyone that needs this fix should use this script instead: https://rawgit.com/freeCodeCamp/testable-projects-fcc/master/build/bundle.js
