This would be better suited for the processwire-requests repository. I would recommend closing this issue and reopening it there.

While I agree that we should have tests for core code (unit test, integration tests, whatever combination makes most sense) and firmly believe it would make ProcessWire more robust and less error prone on updates (Ryan is awesome, but human errors do still happen), having unit tests is not a bug/issue in itself :)
