For testing antivirus we have EICAR, for SPAM, we have GTUBE.

Is there a standard site that is or should be included in blacklists that you can use for testing instead of going to your favorite porn site in front of your boss, the CEO, or someone else who feels that seeing such a site is an excuse for a sexual harassment suit?

Update

This is less about getting permission for me to test, though that answer is useful. I do have both permission and responsibility to actually make sure the filter is running. I am able test the filter is functioning with a netcat.

Instead, I am hoping there is a standard domain name that is blocked by most/all filters for testing. I need to be able to share this with my boss and users.

I need to be able to demonstrate what happens when someone go to a filtered page. I need to have a way to quickly prove to others that the filter is working without asking them to go to some site that will not cause grief if for some reason the filter is not working.

If there isn't already a good domain for this purpose I may simply have to register a domain myself, and then add the domain to all the filters I am responsible for.
