Pick solder nubs on either side of the scratch that are on the same channel. You can see the channels on the board, so just trace along it and find exposed solder on either end
Amd then use a meter to check continuity on each side.
Do this for multiple traces.
But, your rule of thumb is if you cant see the copper its very likely undamaged. The scratch is white colored which means it hasn't even gone through the protective coating yet. If you see copper then you need to worry about doing continuity tests.
