This is achieved by testing the same DUT application +version between releases of CSIT test system. + +CSIT test environment versioning scheme ensures integrity of all the +test system components, including their HW revisions, compiled SW code +versions and SW source code, within a specific CSIT version. Components +included in the CSIT environment versioning include: + +- Server hosts hardware firmware and BIOS (motherboard, processsor, NIC(s), accelerator card(s)). +- Server host Linux operating system versions. +- Server host Linux configuration. +- TRex Traffic Generator version, drivers and configuration. +- CSIT framework code. + +Following is the list of CSIT versions to date: + +- Ver. 1 associated with CSIT rls1908 git branch as of 2019-08-21. +- Ver. 2 associated with CSIT rls2001 git branch as of 2020-03-27. +- Ver. 3 interim associated with master branch as of 2020-xx-xx. +- Ver. 4 associated with CSIT rls2005 git branch as of 2020-06-24. + +To identify performance changes due to VPP code changes from v20.01.0 to +v20.05.0, both have been tested in CSIT environment ver. 4 and compared +against each other.
