This is more fun than it looks, but it's doable.

What's the reason for doing the testing though? Production line, acceptance
of product, hobby, or something else?

RPM can be a hall device, or (easier to balance) just white and black tape
on the shaft.  You have a counter on the pic, so you can count turns for a
while, then decide what to do with the result

Couple your motor to a DC generator (another motor) and measure output power
into a given load. Since the generator is a constant, the variable is the
motor under test.

Current can be done with a shunt or hall effect sensor (6A = 6 Gauss)

Torque is a fun measurement, I'm not sure that you can really do that one
easily. You need something like a prony brake. (it's torque at some
particular speed you want, right?  Locked rotor torque is
position-dependent, and much easier to measure.

Horsepower in which terms, input or output?  I'd want power out versus power
in.
