End to End Tests

End-to-End tests is written by Golang using Ginkgo. To run this tests, we need Docker and Golang.

Before running tests, we need following command in the e2e directory.

$ make setup

BGP

In this test, we prepare testing topologies by Containerlab.

To run the bgp e2e test, please execute the following command.

$ make bgp-e2e

We confirm following points in this test.

• Establish peers with other routing softwares.
  • FRR
  • GoBGP
• Establish iBGP and eBGP peers.
• Receive paths from iBGP and eBGP peers.
• Advertise paths to iBGP and eBGP peers.

Kubernetes

We need to run additional commands to setup a kubernetes cluster and external routes and install Sart related resources.

$ make kubernetes
$ make install-sart

After that, we can run the test.

make kubernetes-e2e

This is the topology for kubernetes e2e test.

This tests confirm that following points.

• Establish BGP peers via Kubernetes custom resources.
• Assign external ip addresses to LoadBalancer services.
  • Specify an address pool.
  • Request a specific address.
  • Specify multiple address pool.
  • Change the address pool.
• Communicate with an external client via LoadBalancer.
  • externalTrafficPolicy=Local
  • externalTrafficPolicy=Cluster
  • Change the externalTrafficPolicy
• Restart
  • sartd-agent
  • sartd-bgp
  • sart-controller

CNI

To set up a CNI e2e test environment, we need following commands.

$ make kubernetes MODE=cni
$ make install-sart MODE=cni

After that, we can run the test.

$ make cni-e2e

The following figure shows the topology for CNI e2e test.

This test confirm that following points.

• Establish BGP peers via Kubernetes custom resources.
• Assign an IP address to pods from the auto assignable pool
• Assign an IP address to pods from the non auto assignable pool
• Connectivity of pods in the cluster
• Restart
  • sartd-agent
  • sartd-bgp
  • sart-controller
