  The Cherenkov Telescope Array (CTA) is the planned next-generation instrument
for ground-based gamma-ray astronomy, currently under preparation by a
world-wide consortium. The FlashCam group is preparing a photomultiplier-based
camera for the Medium Size Telescopes of CTA, with a fully digital Readout
System (ROS). For the forthcoming mass production of a substantial number of
cameras, efficient test routines for all components are currently under
development. We report here on a test facility for the ROS components. A test
setup and routines have been developed and an early version of that setup has
successfully been used to test a significant fraction of the ROS for the
FlashCam camera prototype in January 2016. The test setup with its components
and interface, as well as first results, are presented here.
