testing for shared neutrals

Test for continuity between neutrals on different circuits. There shouldn;t be any.
Or do you mean borrowed neutrals? If so testing for them isn't always doable, not easily anyway. A lot of variables, but the common one is the landing light so it's easy enough to test what is connected to what if there's split up\down lighting circuits.
There's a thread on this subject somewhere else from quite recentyl, I'm surprised it didn;t come up when you were typing the subject of this thread in.

I would look at it ascoffeea borrowed neutral i'd call as a circuit or spur having no neutral at the board but connected to another circuits neutral.
agree?
One circuit supplied by TWO fuses or circuit breakers.
Such that BOTH fuses/breakers must be isolated to make the circuit safe!
Obvious this arrangement does NOT comply with regs!

a few angles eh SL
one method would be to isolate one circuit and remove neutral from busbar. turn all lights on. if this neutral is live at any point, borrowed neutral. then test again with other circuit isolated
