Network virtualization has dramatically modified our architectures which asks for more automation and powerful testing tools like Functest, a collection of state-of-the-art virtual infrastructure test suites, including automatic VNF testing (cf. [1]).
In context of OPNFV, Functest verifies any kind of OpenStack and Kubernetes deployments including production environments. It conforms to upstream rules and integrates smoothly lots of the test cases available in the opensource market. It includes about 3000+ functional tests and 3 hours upstream API and dataplane benchmarks. It’s completed by Virtual Network Function deployments and testing (vIMS, vRouter and vEPC) to ensure that the platforms meet Network Functions Virtualization requirements. Raspberry PI is also supported to verify datacenters as the lowest cost (50 euros hardware and software included).

To test a Kubernetes without access to Internet, repository mirrors needs to be provided.
Currently, all tests supports this feature except cnf conformance.
There's two ways for providing the repository mirrors:
- Give an environment variable (
MIRROR_REPO) which gives a repository with all needed images. - Gives an environment variable per needed repo:
DOCKERHUB_REPOfor DockerHub repository (docker.io)GCR_REPOfor Google Cloud repository (gcr.io)K8S_GCR_REPOfor Kubernetes repository (k8s.gcr.io)QUAY_REPOfor Quay repository (quay.io)
All needed images are given in functest_kubernetes/ci/images.txt
For e2e tests, docker.io is hardcoded. it does mean that you'll have to set up
a mirror on docker. An example on how to set it up on docker daemon is provided
here:
