Why can't you shave arm hair with you serrated blades? They should be able to do so if you want to get them sharpened in that manner you just need to polish to the necessary grit size.
Anyway, the three tests I use for sharpness are:
1) see if the blade will catch on my thumb nail if pulled edge wise down across it (blade held perpendicular to direction of pulling)
This tests for a nice thin edge and makes sure no burr is formed (on one side the knife will grip well on the other side it will slip)
2) run the blade across a rough section of my hand to see how it bites
This makes sure that the edge has the required smooth microserration pattern I am looking for
If the sharpening is to a suficiently high grit then I'll try a shaving test just becuase its cool, if it passed the above two it will not fail this anyway.
These tests can be done very quickly while sharpening then once they are passed I proceed to the final test.
3) try to cut suitable materials
These test can be done on serrated blades as well with slight modifications, for example I have a hard plastic dowel that I use intead of my thumb nail on serrated blades.
