then you do not have to do anything.. the PCB manufacturer gets that from the gerber / ODB++ file

No, I do not mean test point after assembly and debug time. My question is about Electrical Test (Flying Probe) and test point for PCB manufacturing time.

You do not need to do anything. PCB manufacturer can design the test procedure based on gerbers (or other data files what you sent them to manufacture your PCB e.g. ODB++). For testing, they like ODB++ (because it has more information), but gerbers are just fine.

Very important - Always do Electrical testing!
PS: They use pads - they do not need any special testpoints. They need to test every single track anyway - you would not be able to put there so many testpoints.

Test Pad
Hi Guys,
I am wondering when we ask PCB manufacturer to do electrical test, how they actually find the test points? Is this true: any SMD or TH pad will be test point? Or we need to define test points explicitly?
