Environment Versioning
----------------------
-In order to determine any benchmark anomalies (progressions,
-regressions) between releases of a specific data-plane DUT application
-(e.g. VPP, DPDK), the DUT needs to be tested in the same test
-environment, to avoid test environment changes impacting the results and
-clouding the picture.
+CSIT test environment versioning has been introduced to track
+modifications of the test environment.
-In order to enable test system evolution, a mirror scheme is required to
-determine benchmarking anomalies between releases of specific test
-system like CSIT. This is achieved by testing the same DUT application
-version between releases of CSIT test system.
+Any benchmark anomalies (progressions, regressions) between releases of
+a DUT application (e.g. VPP, DPDK), are determined by testing it in the
+same test environment, to avoid test environment changes clouding the
+picture.
+
+A mirror approach is introduced to determine benchmarking anomalies due
+to the test environment change. This is achieved by testing the same DUT
+application version between releases of CSIT test system. This works
+under the assumption that the behaviour of the DUT is deterministic
+under the test conditions.
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.
+- **HW** Server hardware firmware and BIOS (motherboard, processsor,
+ NIC(s), accelerator card(s)), tracked in CSIT branch in
+ :file:`./docs/lab/<server_platform_name>_hw_bios_cfg.md`, e.g. `Xeon
+ Skylake servers
+ <https://git.fd.io/csit/tree/docs/lab/testbeds_sm_skx_hw_bios_cfg.md#n556>`_.
+- **Linux** Server Linux OS version and configuration, tracked in CSIT
+ Reports in `SUT Settings
+ <https://docs.fd.io/csit/master/report/vpp_performance_tests/test_environment.html#sut-settings-linux>`_
+ and `Pre-Test Server Calibration

+- **CSIT** CSIT framework code tracked in CSIT release branches.

-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. All substantial progressions has been marked up with
-RCA analysis. See Current vs Previous Release and Known Issues.

CSIT environment ver. 4 has been evaluated against the ver. 2 by
benchmarking VPP v20.01.0 in both environment versions.
