DRAFT PROPOSAL: CSIT functional tests re-organisation


CSIT functional job included too many test cases per VPP patch and took quite a long time to execute - vpp-csit-verify-virl-master job used to take 1 hour of execution. To address it, following actions have been taken:

  • identify test cases that can be skipped in case of vpp-csit-verify-virl-{branch} job execution:
    • tests covered by unittests in vpp (make test)
    • tests covering old/obsolete/unmaintained vpp code
    • tests covering features with limited use
    • scale tests / combined tests
  • apply special tag to these test cases
  • adapt corresponding bootstrap files to exclude these test from execution per VPP patch

All test cases skipped per VPP patch are executed by csit weekly and semi-weekly jobs.

    • Eth2P-Ethip6-Ip6Base-Ip6Ipfixbase-Func - TC04

test case tag

New tag SKIP_VPP_PATCH has been introduced to identify test cases to be excluded from execution in case of vpp-csit-verify job (i.e. per VPP patch) but not to be skipped in case of csit-vpp-verify job (i.e. per CSIT patch).

bootstrap files

Bootstrap files have been adapted to exclude from execution test cases tagged with SKIP_PATCH tag only (CSIT patch) or test cases tagged with SKIP_PATCH or SKIP_VPP_PATCH tags (VPP patch).


Overall execution time of vpp-csit-verify-virl-master job has been reduced to 40mins - it means 20 mins gain per VPP patch with current implementation.
