How about the ability to designate your own ship as a target for weapon testing? In this game, you might not see a single alien for a hundred years. And even if you do see one, firing at them just for testing feels kind of inhumane. For example, I have a station for defending the gate, but I have absolutely no idea how it would perform in actual combat, since I’ve never fought anyone so far.
To avoid blowing up the ship along with the entire crew, you can evacuate it. And if you need to test the defense systems, you can make the ship itself indestructible.
