sorry for this experience.

when I started in this hobby, i was taught to test the pcb first before building.

How do you do that? Check continuity for everything?

Just plug it in and use a pair of tweezers to link the sockets. When they’re good to go, the press will register on whatever software you’re using.

But that means you have to solder an Arduino or whatever to it first

You don’t have to solder anything on a PCB before testing it. Just plug it in and bridge the sockets with tweezers.

Edit: I guess some of the barebones builds that are seen in the community will often need soldering prior to testing (diodes, etc.), but these are not common and the majority of keyboard PCBs can be tested without the need to solder.

For most PCBs, the controller and resistors are already soldered on. Just plug the PCB into your computer's USB port and got to keyboardtester.com or similar and bridge each set of pins. When you press a switch, the leafs make contact and bridge the connection. So bridging the pin sockets with a metal tweezers is doing the same thing.

Oh ok I didn’t know they come with electronics preinstalled
