Can you leave a 4" line cleanout in the ground? Only used for testing purposes and then bury it?

Typically I would use a wye and double wye assembly but my new boss doesn't have one. Thank you

If it was only used for testing then its not a cleanout, its a test tee and doesn't need to be made accessible.
