   6 Environment Versioning
   7 ----------------------
   8
   9 CSIT test environment versioning has been introduced to track
  10 modifications of the test environment.
  11
  12 Any benchmark anomalies (progressions, regressions) between releases of
  13 a DUT application (e.g. VPP, DPDK), are determined by testing it in the
  14 same test environment, to avoid test environment changes clouding the
  15 picture.
  16 To beter distinguish impact of test environment changes,
  17 we also execute tests without any SUT (just with TRex TG sending packets
  18 over a link looping back to TG).
  19
  20 A mirror approach is introduced to determine benchmarking anomalies due
  21 to the test environment change. This is achieved by testing the same DUT
  22 application version between releases of CSIT test system. This works
  23 under the assumption that the behaviour of the DUT is deterministic
  24 under the test conditions.
  25
  26 CSIT test environment versioning scheme ensures integrity of all the
  27 test system components, including their HW revisions, compiled SW code
  28 versions and SW source code, within a specific CSIT version. Components
  29 included in the CSIT environment versioning include:
  30
  31 - **HW** Server hardware firmware and BIOS (motherboard, processsor,
  32   NIC(s), accelerator card(s)), tracked in CSIT branch in

  34   Skylake servers
