End-to-end (e2e) testing is automated testing for real user scenarios.
Build and run test
Prerequisites:
a running k8s cluster and kube config. We will need to pass kube config as arguments.
Have kubeconfig file ready.
Have etcd operator image ready.
e2e tests are written as Go test. All go test techniques apply, e.g. picking
what to run, timeout length. Let's say I want to run all tests in "test/e2e/":
$ go test -v ./test/e2e/ --kubeconfig "$HOME/.kube/config" --operator-image=quay.io/coreos/prometheus-operator
