  The Simons Observatory (SO) is a ground-based cosmic microwave background
instrument to be sited in the Atacama Desert in Chile. SO will deploy 60,000
transition-edge sensor bolometers in 49 separate focal-plane modules across a
suite of four telescopes covering three dichroic bands termed low frequency
(LF), mid frequency (MF) and ultra-high frequency (UHF). Each MF and UHF
focal-plane module packages 1720 optical detectors and corresponding 100 mK
microwave SQUID multiplexing readout components. In this paper we describe the
testing program we have developed for high-throughput validation of the modules
after they are assembled. The validation requires measurements of the yield,
saturation powers, time constants, noise properties and optical efficiencies.
Additional measurements will be performed for further characterizations as
needed. We describe the methods developed and demonstrate preliminary results
from initial testing of prototype modules.
