Help install pendant lights in kitchen

Recently moved into a new house in CA, USA. Looking to install 2 pendant lights over kitchen countertop. The house is relatively new construction (2018). I find two junction boxes in the ceiling over the countertop, clearly meant for 2 lights. In one of the boxes (call it BoxA) I see three wires as expected - black, white and bare but no power when tested with non-contact tester. And in the other (BoxB), there are 2 sets of black, white and bare wires (total 6) none of which are connected. Only one of the 2 black wires in BoxB is live, that too only when switched on ( yes, found a switch on the wall that controls it). It seems like they are daisy chained - the second set of wires in BoxB are meant for feeding the power to the next junction box (BoxA) so both the boxes are controlled by a single switch. This makes most sense to me but how to confirm this? Is it safe to connect the same color wires in BoxB and check for power in BoxA? Or could this be a switch loop? If so, how to check? As I mentioned earlier, none of the wires were connected when I opened the Box. Any guidance is much appreciated. TIA.

I think your original assumption it correct. Switched power is coming from the switch to box b and is fed through to box a.

A simple ohm meter can be used to check continuity of wirers between boxes.

I am assuming I need to connect the wires in BoxB to check the continuity between BoxB and BoxA. Is that correct?

When we discuss wire quantities we don't include the ground wire. It's there and gets connected.

I would just connect the wires together (black to black and white to white) in box B.
Power the circuit up and check for power between black and white at both A and B boxes.

If you want to use an ohmmeter to test a cable. Make sure the power is off.
Short white to black at one end. Check for short from white to black at other end.

Nope, you already confirmed wire #1 from switch to box A!

Cornet white and black of wire #2 in Box A and check for short between black and white in Box B.

If it shorts it's the same wire and your good to go!

Another option, assuming the boxes are close together, short wire #2 (black then white) between Box A and B (assuming your ohm meter leads are sufficiently long) and that will be same confirmation as above.

Thank you so much for your advice. I was able to confirm the continuity between boxA and boxB with the ohm meter. Successfully installed the pendant lights. My first diy project
Thanks to you.
