Overview

Package cases contains router acceptance cases that can be integrated into the braccept binary.

The process to add a new case is the following:

Step 0. Refer to the following for the test's setup:

  • Overview: acceptance/router_multi/topology.drawio.png
  • Topology Details: acceptance/router_multi/conf/topology.json
  • MAC Addresses: acceptance/router_multi/test.py Note that all MAC addresses of interfaces on the far side of the A/B/C/D routers are identical: f00d:cafe:beef

Step 1. Add a new file with a representative name e.g. cases/child_to_child_xover.go

Step 2. Create a function inside that file which returns the new br accept testcase. 

// ChildToChildXover  <ADD DESCRIPTION>
func ChildToChildXover(artifactsDir string, mac hash.Hash) runner.Case {

...

	return runner.Case{
		Dscr:     "ChildToChild",
		WriteTo:  "veth_151_host",
		ReadFrom: "veth_141_host",
		Input:    input.Bytes(),
		Want:     want.Bytes(),
	}
}

Step 3. In the braccept/main.go, include the above function 

multi := []runner.Case{
	cases.ChildToParent(artifactsDir, mac),
	cases.ChildToChildXover(artifactsDir, mac),
}

Step 4. Do a local run, which means set up a working router, execute the braccept, shutdown the router. This is done in sequence by: 

bazel test acceptance/router_multi:all --config=integration --nocache_test_results

Functions

func ChildToChildXover
