the obvious solution to your " engine test bed " conundrum is to locate it adjacent to your power plant - and use ducting to vent the exhaust gasses
and extracted air from your engine test beds up the flue of the base furnaces .
the art of deception / concealment is not to attempt to make your covert activity " disapear" but to make observers think that an obvious and
mundane source of similar emmisions to the ones you wish to conceal is the cause of all such emmissions
if your " secret base " activities will generate unusual levels of radiation - build a nuclear powerplant @ the same site - it will both sheild you
from prying eyes - provide free power and give you an excellent outer security perimeter
if it is going to generate large amounts of foul odours - build a waste recycling and incineration plant as a " cover structure "
etc etc
what ever the " unusual " activity that would stand out like a soore thumb - there is a "harmless " and mundane process which can be used to mask
and sheild the activity you wish to keep secret .

I thought it might have been Wired, but I guess not. I also thought that it was a missile silo facility, but I guess not. IIRC the reporter
from the magazine was taken to the facility which looked like a normal building in the moscow suburbs.
