SAI Challenger

SAI testing and integration framework for any SAI oriented devices. The main ideas behind SAI-Challenger are:

  • testbed agnostic test cases - test case code does not require any changes for running in any type of environment - HW, emulation, different test equipment, links, servers, etc.;
  • decoupling real SAI RPC implementation from test cases code - test code looks similar for configuring device using Thrift, Redis, etc.;
  • traffic generator agnostic interface - possibility to use both SW and HW traffic generators that support snappi API;
  • fully dockerized environment;

SAI Challenger sources

To get SAI Challenger sources:

git clone https://github.com/opencomputeproject/SAI-Challenger.git
cd SAI-Challenger/
git submodule update --init

Applications

SAI Challenger has many applications. A partial list is below:

  • Virtual and Physical testbeds
  • Testing and debugging libsai using saithrift, independent of any Network Operating System (NOS)
  • SONiC-SAI Integration and test using sairedis
  • CI/CD and regression testing of virtual or physical DUTs
  • DUT performance testing using HW traffic generators
  • PHY (transceiver) device testing & qualification
  • Ubrella test harness for native SAI Challenger test cases as well as legacy SAI-PTF test cases, using a single-pane-of-glass to reduce testbed complexity.

Use-case scenarios

SAI Challenger has many configuration options, resulting in numerous permutations of:

  • Physical or virtual DUT testing
  • DUT Configuration APIs - saithrift or sairedis
  • Dataplane (packet test) - PTF/Scapy or OTG/snappi.

See Use-Cases README for more details.
