Here is some information about board farms.
At the Embedded Linux Conference Europe 2017 Andrew Murray held a BoF session titled Farming Together. The purpose of this BoF was to bring together people that are actively working on board farms to create a community, to knowledge share and to start a collaborative effort.

At present the expectation is to hijack this mailing list - https://lists.yoctoproject.org/listinfo/automated-testing
- create a mailing list?
- define API between test framework and DUT controller layer?
- ttypersist: provides an application a fake socket for misbehaving ttys
- survey of existing tools, hardware, practices
- collection of presentations?
- that is, add a list of presentations on this topic from previous conferences

- spend money on USB serial adapter cables - cheap adapters sometimes drop connections and are a pain to debug
- FTDI cables seem to work well.
