Is there anyway to get physical test ads in the editor? ADMOB

I'm sure this is asked a lot but can't seem to find anything on google.
Would like to have a test ad in the editor so i can make sure all my UI elements are not covering/too close to them, is there any easy way of doing so or is it best to just create an IMG roughly the same size as one and anchor it to the bottom middle? I'm sure that will work fine but may not be accurate when testing multiple screen sizes.

 

As far as I'm aware there is no way to display real or test ads from admob inside the editor.

Your best bet is probably to just use mock up images as your ad placeholder, unfortunately.
