It is hard to find exact tests, cause we'll need separate tests for all
possible combinations - new cable is defined in standard, maybe you can
find some tests via Google.

A plenty of that, also Google a little bit. Therefore, whenever you have
any kind of high-speed copper connection, twisted pair must be used to
reduce the noise in the cable. You can find, also, twisted ribbon cable
(pretty standard cable in SCSI).
