Why testing VLSI circuit is non essentia

Suppose you had a following configuration

************
* *---------N1
* * |
* * Resistor R
* circuit * |
* * *N2
* *
* *---------N3
************

Now The voltage across N1 N3 = V13

V23 = V13 - I12*R

See I12 = dQ/dt

but dt = 0
Kdt = 0 = dt

I12 = dQ/dt /K

V23 = V13 - dQ/dt/K * R
= V13 - I12/K*R

voltages will dramatically vary, making any kind of over test useless.
