I am making a new pcb, and I want the pcb maker to check it, because it has fairly tight tolerances and lots of blind vias. I know that the NC drill file format tells cam machines where to drill holes.

Is there a similar file format that tells the electrical testing machine at which coordinates to check continuity between pads?

Most manufactures have electrical check and they make the testing scheme from the gerber files. This is only a check box you must tick in when you order. You can test this at http://pcbcart.com a very good place. See pic here
