# FD.io CSIT Testbed Versioning
CSIT test environment versioning has been introduced to track modifications of
the test environment.
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.
To beter distinguish impact of test environment changes, we also execute tests
without any SUT (just with TRex TG sending packets over a link looping back to
TG).
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:
- **HW** Server hardware firmware and BIOS (motherboard, processsor,
NIC(s), accelerator card(s)), tracked in CSIT branch.
- **Linux** Server Linux OS version and configuration, tracked in CSIT
Reports.
- **TRex** TRex Traffic Generator version, drivers and configuration
tracked in TG Settings.
- **CSIT** CSIT framework code tracked in CSIT release branches.
