Ok, I was going to plug the 7pin into the truck and test each of the 6 ends. Turn on left signal - test...etc...
Turn on right signal - test
brake - test
brake controller - ??
12v charge - ?

That sounds about right, F5 has a good point on your test battery connect the NEG to ground on the camper, then use your test light to ground on the camper. this ensures all the grounds are OK, and if it's gonna take you longer than me a heavier battery might be better. I used a small one back then because I didn't trust the camper wiring and didn't want to get bit hard

For the brake controller not sure how to "test" that without a lot of wire between controller and trailer but since you have a new vehicle it's a safe bet the wiring is correct on the truck side. I'd make sure everything else is wired right then plug it in and make sure your controller "sees" your camper.

I would not worry about testing for the brake controller. You will have six circuits (backup lamps are usually not an option on smaller trailers)
Connector connect; NO light on. Find the 12 volt wire for the battery feed. Check it off.
Turn on headlamps, find 12 volts for the running/clearance lamps on the trailer. Check that circuit off.
Turn on left signal, find that circuit. Check it off
Turn on right signal, find that circuit. Check it off.
That's four circuits, as someone already noted the one showing the male terminal in the 6-pin is most likely ground.
That's five circuit, the last one is the brake controller. I believe it outputs a varying voltage. So have someone SLOWLY apply the brakes, and I believe (just guessing since I always use a digital volt meter), the test lamp will slowly get brighter until the brake is fully applied at which point a full voltage signal is sent to the brakes.
