I have an Arduino project that has 15 different output pins set. Some are currently attached to devices and others are not. Will testing my program cause a problem / damage if it sets pints to HIGH that do not have anything connected to them?

Nope, you should be just fine.
Having a pin set to any state while unplugged will not cause any problems with your microcontroller.
