How would he/she go about testing the integrity of the circuit? Do you mean
continuity?

There's a standard way to test the integrity of a ring circuit
(a google search of this newsgroup will turn it up, or you can
find it in the On-Site Guide or the Inspection and Testing notes
book to supplement the Wiring Regs). Basically, the resistance of
the live and neutral loops are checked to be the same, and the
CPC to be as expected, and a check for cross-connected ring is
performed. The resistance is ideally measured using a high
current low voltage source, to tease out bad connections (which
a bog standard multimeter can easily miss).
