4 .. _test_environment_versioning:
9 CSIT test environment versioning has been introduced to track
10 modifications of the test environment.
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
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).
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.
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:
31 - **HW** Server hardware firmware and BIOS (motherboard, processsor,
32 NIC(s), accelerator card(s)), tracked in CSIT branch.
33 - **Linux** Server Linux OS version and configuration, tracked in CSIT
35 - **TRex** TRex Traffic Generator version, drivers and configuration
36 tracked in TG Settings.
37 - **CSIT** CSIT framework code tracked in CSIT release branches.
