**DRAFT - WORK IN PROGRESS - PLEASE TREAT IT AS SUCH **

CSIT development plan - background

CSIT test development priorities are aligned with VPP releases timeline, with relative dev work prioritization for each VPP release driven by perceived importance of test verification for VPP functionality and performance. Specific CSIT dev work priorities are driven by rough consensus within the project and contributors and committers availability and willingness to do work.

Following priority tagging scheme is used in this CSIT wiki and FD.io jira for CSIT:

  • [$VppRlsNo-$RelPrio]

    • VppRlsNo - aligned VPP release number - 16.09, 16.12, 17.03.
    • RelPrio - CSIT release priority - P0 for Must Have, P1 for Should Have, P2 for Could Have

  • CSIT dev work tagging examples:

    • [1609-P0] - CSIT Must Have for vpp-v1609
    • [1609-P1] - CSIT Should Have for vpp-v1609
    • [1609-P2] - CSIT Could Have for vpp-v1609

CSIT dev work plan execution tracked on CSIT jira, with priority tags encoded as Jira labels for easy of tracking and reporting.

CSIT performance tests - dev plan

CSIT performance test cases devevelopment work is grouped and tracked across the following VPP functional areas:

  1. IPv4 data plane
  2. IPv4 control plane
  3. IPv4 encapsulations
  4. IPv4 telemetry
  5. IPv6 data plane
  6. IPv6 control plane
  7. IPv6 encapsulations
  8. IPv6 telemetry
  9. Ethernet L2 data plane
  10. Ethernet L2 control plane
  11. Ethernet L2 encapsulations
  12. Ethernet L2 telemetry
  13. MPLS data plane
  14. NSH data plane

CSIT team is tracking completed CSIT dev work per above area (completed = test cases running in FD.io), as well as top-level test coverage metric [%] of VPP functions. VPP code development dependencies are marked with [VPP-DEP]. Performance tests require the functional tests to be completed - see sub-sections "Functional tests preconditions".

CSIT performance tests are split into the two main groups:

  • NDR(PDR) throughput discovery - tests searching for NDR non-drop rate throughput or PDR partial-drop rate throughput for specified configuration. Also referred to as "long" tests.
  • refNDR throughput verification - tests verifying code patches against the reference NDR throughput. Also referred to as "short" tests.
