Is it ok to run the engine hard mounted on a test stand, or should it have some shock absorbing mounting?

Have never used a test stand for breaking in an engine. Actually, I have only mounted the engines in the models, started them, tuned them, ran a tank of fuel thru them, then off to the flying field. All my engines have been broke in, in flight. To date, never had a engine problem, with my engines.
