That would just leak the pressure, right? Should I just block it off?

Just like a radiator cap, the tester cap seals below the level of the overflow nipple. There is no need to block anything; just connect the test cap and pump up the pressure.

If you are just testing for external leaks, pump the pressure up to 15-20 psi, then look and listen.
