PCB testing methods during manufacturing and assembly?

We plan to visit factory next week. Could we know more about how many basic PCB testings in EMS field?
  1. VISUAL INSPECTION
  2. IN-CIRCUIT TESTING (ICT)
  3. FLYING PROBE TESTING（FPT）
  4. AUTOMATED OPTICAL INSPECTION (AOI)
  5. AUTOMATED X-RAY INSPECTION（AXI）
  6. FUNCTIONAL TESTING (FCT)
  7. BURN-IN TESTING

What Others Are Asking

Is solder mask a valid electrical insulator?

There is a copper pour over the entire top of the my PCB, which is part of GND net. It turns out that the surface mounted 1W LEDs I’m going to use have the heat slug connected internally to the LED’s +ve terminal. Can I rely on the solder mask to insulate the +ve voltage (~3V ish) from GND? Long term?
