This repository hosts equivalent Go and Python tests written using snappi against a back-to-back connected ixia-c topology.

• Recommended OS is Ubuntu LTS release.
• At least 2 CPU cores
• At least 6GB RAM
• At least 10GB Free Hard Disk Space
• Go 1.17+ or Python 3.6+ (with pip)
• Docker Engine (Community Edition)
• License:
  • Test(s) in this repository which contain only 'flows' or 'bgp' would not require license with ixia-c.
  • License of ixia-c would be required for test(s) which use other control-plane protocols e.g. 'isis', 'lacp', "ospfv2" etc.
  • For further details, please refer to ixia-c licensing documentation or contact ixia-c support.

1. Clone this repository

   git clone https://github.com/open-traffic-generator/conformance.git && cd conformance

2. Deploy topology

   # use DP-only distribution of ixia-c
   ./do.sh topo new dp
   
   # use CP/DP distribution of ixia-c
   # enter GITHUB PAT instead of password when prompted for credentials
   ./do.sh topo new cpdp

   Once deployment is done, test-config.yaml is automatically generated in present working directory and can be used to customize test run

3. Setup and run Go tests

   # run all feature tests against DP-only distribution of ixia-c
   ./do.sh gotest -tags="dp" ./feature/b2b/...
   # run all feature tests against CP/DP distribution of ixia-c
   ./do.sh gotest -tags="all" ./feature/b2b/...
   
   # run single test
   ./do.sh gotest ./feature/b2b/packet/udp/udp_port_value_test.go

4. Setup and run Python tests

   # setup test requirements
   ./do.sh prepytest
   
   # run all tests against DP-only distribution of ixia-c
   ./do.sh pytest -m dp ./feature/b2b/
   # run all tests against CP/DP distribution of ixia-c
   ./do.sh pytest ./feature/b2b/
   
   # run single test
   ./do.sh pytest ./feature/b2b/packet/udp/test_udp_port_value.py

5. Teardown topology

   # remove DP-only distribution of ixia-c
   ./do.sh topo rm dp
   
   # remove CP/DP distribution of ixia-c
   ./do.sh topo rm cpdp

1. Format python code

   Note that if you submit any code which does not follow proper python format the CI will fail

   # to format python code
   ./do.sh pylint
   
   # to format python code for a specific path
   ./do.sh pylint features

2. Format go code

   Note that if you submit any code which does not follow proper go format the CI will fail

   # to format go code
   ./do.sh golint
   
   # to format go code for a specific path
   ./do.sh golint helpers

3. Run perf tests in Go

   # run single perf test
   ./do.sh gotest ./performance/b2b/udp_mesh_flows_perf_test.go
   # run single perf test with lesser number of iterations (default=100)
   OTG_ITERATIONS=2 ./do.sh gotest ./performance/b2b/udp_mesh_flows_perf_test.go

4. Run tests against ixia-c B2B deployed on K8S cluster using eth0 as test interface

   # setup K8S cluster
   ./do.sh new_k8s_cluster
   # create topology
   ./do.sh topo new k8seth0
   # run single test
   ./do.sh gotest ./feature/b2b/packet/udp/udp_port_value_eth0_test.go
   # delete topology
   ./do.sh topo rm k8seth0
   # delete K8S cluster
   ./do.sh rm_k8s_cluster

5. Run tests against KNE cluster (Back-To-Back)

   # setup KNE cluster
   ./do.sh new_k8s_cluster kne
   # create KNE topology
   ./do.sh topo new kneb2b
   # run all back-to-back feature tests
   ./do.sh gotest -tags="all" ./feature/b2b/...
   # delete KNE topology
   ./do.sh topo rm kneb2b
   # delete KNE cluster
   ./do.sh rm_k8s_cluster kne

6. Run tests against KNE cluster (Port-Dut-Port)

   # setup KNE cluster
   ./do.sh new_k8s_cluster kne arista
   # create KNE topology
   ./do.sh topo new knepdp arista
   # run all port-dut-port feature tests
   ./do.sh gotest -tags="all" ./feature/pdp/...
   # delete KNE topology
   ./do.sh topo rm knepdp arista
   # delete KNE cluster
   ./do.sh rm_k8s_cluster kne arista
