How do you develop if you cant test in editor?

I cant find any information on this so I assume that the question asked (cant test in editor) in the title is actually correct.

Do you make a change, build and then download to your phone? It seems incredibly inefficient or am I missing something?

Unity is working on remoting for AR Foundation.

There are existing packages in the Unity Asset Store that provide remoting functionality for AR Foundation.
