1.2. General Notes¶
All CSIT test results listed in this report are sourced and auto-generated from output.xml Robot Framework (RF) files resulting from LF FD.io Jenkins jobs execution against VPP-17.04 release artifacts. References are provided to the original LF FD.io Jenkins job results. However, as LF FD.io Jenkins infrastructure does not automatically archive all jobs (history record is provided for the last 30 days or 40 jobs only), additional references are provided to the RF result files that got archived in FD.io nexus online storage system.
FD.io CSIT project currently covers multiple FD.io system and sub-system testing areas and this is reflected in this report, where each testing area is listed separately, as follows:
- VPP Performance Tests - VPP performance tests are executed in physical FD.io testbeds, focusing on VPP network data plane performance at this stage, both for Phy-to-Phy (NIC-to-NIC) and Phy-to-VM-to-Phy (NIC-to-VM-to-NIC) forwarding topologies. Tested across a range of NICs, 10GE and 40GE interfaces, range of multi-thread and multi-core configurations. VPP application runs in host user- mode. TRex is used as a traffic generator.
- Testpmd Performance Tests - VPP is using DPDK code to control and drive the NICs and physical interfaces. Testpmd tests are used as a baseline to profile the DPDK sub-system of VPP. Testpmd performance tests executed in physical FD.io testbeds, focusing on Testpmd data plane performance for Phy- to-Phy (NIC-to-NIC). Tests cover a range of NICs, 10GE and 40GE interfaces, range of multi-thread and multi-core configurations. Testpmd application runs in host user-mode. TRex is used as a traffic generator.
- VPP Functional Tests - VPP functional tests are executed in virtual FD.io testbeds focusing on VPP packet processing functionality, including network data plane and in -line control plane. Tests cover vNIC-to-vNIC vNIC-to-VM-to-vNIC forwarding topologies. Scapy is used as a traffic generator.
- HoneyComb Functional Tests - HoneyComb functional tests are executed in virtual FD.io testbeds focusing on HoneyComb management and programming functionality of VPP. Tests cover a range of CRUD operations executed against VPP.
In addition to above, CSIT rls1704 report does also include VPP unit test results. VPP unit tests are developed within the FD.io VPP project and as they complement CSIT system functional tests, they are provided mainly as a reference and to provide a more complete view of automated testing executed against VPP-17.04 release.
FD.io CSIT system is developed using two main coding platforms: Robot Framework (RF) and Python. CSIT rls1704 source code for the executed test suites is available in CSIT branch rls1704 in the directory ”./tests/<name_of_the_test_suite>”. A local copy of CSIT source code can be obtained by cloning CSIT git repository - “git clone https://gerrit.fd.io/r/csit”. The CSIT testing virtual environment can be run on a local computer workstation (laptop, server) using Vagrant by following the instructions in CSIT tutorials.
