Here is a test video website that has pop up ads and adblock detection so be warned. In this case, orion should blocks the ads but doesn't pass the adblock detection.

And here is a test video where I find orion doesn't block ads and occasionally fails adblock detection. Again warning for the ads.

And more test video links usually with ads or anti adblock that orion doesn't catch.

But mainly to test for anti adblock detection you can use either the adguard or ublock origin issue reported sites on github as well as they have a list of websites you can try and chances are if it's marked as closed then uBlock Origin or AdGuard could handle it but most likely not Orion.
