FD.io IT systems integration

Three Jenkins jobs involving CSIT functional test cases:

  1. Job name: vpp-csit-verify-virl.
    • Description: Job to test VPP build against verified CSIT functional test cases (a.k.a. "golden CSIT version"), running in VIRL vNet testbeds hosted by LF FD.io.
    • Triggers:
      • VPP patch-based automatic trigger.
      • Manual trigger: Comment "recheck" in proposed patch in VPP project.
    • Status: WORKING.
  2. Job name: csit-vpp-functional-virl.
    • Description: Job to test CSIT patch against verified VPP version (a.k.a. "golden VPP version").
    • Triggers:
      • CSIT patch-based automatic trigger.
      • Mnual trigger: Comment "recheck" in proposed patch in CSIT project.
    • Status: WORKING.
  3. Job name: csit-vpp-master-verify-weekly.
    • Description: Weekly job that validates the latest VPP build against the latest CSIT code. The whole CSIT test suite is run three times in sequence to check stability and consistency of results. Two goals achieved in case of successful run:
      • Verified CSIT test cases ("golden CSIT version") version with tag "csit-verified" used in VPP verify jobs (job name: vpp-csit-verify-virl).
      • Verified VPP version ("golden VPP version") used in CSIT verify jobs (csit-vpp-functional-virl).
    • Triggers:
      • Scheduled to run periodicaly every Sunday at 13:00 UTC.
      • No manual trigger.
    • Status: tagging not working - should be solved by Sunday 17-April 2016.

CSIT functional tests infra work areas

CSIT Golden Branch

  • Name of the CSIT branch is "csit-verified".
  • It is created by CSIT team in CSIT gerrit project.
  • It represents the version of CSIT code that is tested and verified to work perfectly.
  • At the moment, csit-verified is a git branch, stored in gerrit.fd.io, that points to concrete version of master branch of CSIT project.
  • Link to branch: https://gerrit.fd.io/r/gitweb?p=csit.git;a=shortlog;h=refs%2Fheads%2Fcsit-verified
  • In future, we plan to switch from using branch to tag, because is suites gerrit better than branching (since we use the branch only to point to a version in master).

Run testcases based on vpp code change (no clear ideas yet)

  • for now execute all baseline tests - l2, ip4, ip6
  • future per code change functional and vpp node graph dependencies

Gathering of stats/logs/core dumps from DUTs/TGs after test execution:

  • naming schemes, storage, packaging
  • collection of TELEMETRY
  • plain text - structured
    • one-time snapshot of the system
    • for human driven hand-crafted debugging
    • for human driven part-automated debugging
    • for machine driven fully-automated analysis
  • use Network Data Analytics engine in the future

Honeycomb tests framework

  • NETCONF FrameWork
    • library that understands netconf and ssh
  • Existing CSIT RF (Robot-Framework) and Python libraries / tools extension to use HC/VAT/CLI "driver" to execute things
    • the same logical code - execute across different driver APIs
      • HC, VAT, CLI

VPP project

  • plannig and coordinating with code development
  • specifying and identifying dependencies to/from
    • deployment use cases
    • CSIT
