E2E Framework


A Go framework for end-to-end testing of components running in Kubernetes clusters.

The primary goal of this project is to provide a go test(able) framework that uses the native Go testing API to define end-to-end tests suites that can be used to test Kubernetes components. Some additional goals include:

  • Provide a sensible programmatic API to compose tests
  • Leverage Go's testing API to compose test suites
  • Expose packages that are easy to programmatically consume
  • Collection of helper functions that abstracts Client-Go functionalities
  • Rely on built-in Go test features to easily select/filter tests to run during execution
  • And more

For more detail, see the design document.

Getting started

The Go package is designed to be integrated directly in your test. Simply update your project to pull the desired Go modules:

go get
go get

Using the framework

The framework uses the built-in Go testing framework directly to define and run tests.

Setup TestMain

Use function TestMain to define package-wide testing steps and configure behavior. The following examples uses pre-defined steps to create a KinD cluster before running any test in the package:

var (
	testenv env.Environment

func TestMain(m *testing.M) {
    testenv = env.New()
    kindClusterName := envconf.RandomName("my-cluster", 16)
    namespace := envconf.RandomName("myns", 16)

    // Use pre-defined environment funcs to create a kind cluster prior to test run

    // Use pre-defined environment funcs to teardown kind cluster after tests
    // launch package tests

Define a test function

Use a Go test function to define features to be tested as shown below:

func TestKubernetes(t *testing.T) {
    f1 := features.New("count pod").
        WithLabel("type", "pod-count").
        Assess("pods from kube-system", func(ctx context.Context, t *testing.T, cfg *envconf.Config) context.Context {
            var pods corev1.PodList
            err := cfg.Client().Resources("kube-system").List(context.TODO(), &pods)
            if err != nil {
            if len(pods.Items) == 0 {
                t.Fatal("no pods in namespace kube-system")
            return ctx

    f2 := features.New("count namespaces").
        WithLabel("type", "ns-count").
        Assess("namespace exist", func(ctx context.Context, t *testing.T, cfg *envconf.Config) context.Context {
            var nspaces corev1.NamespaceList
            err := cfg.Client().Resources().List(context.TODO(), &nspaces)
            if err != nil {
            if len(nspaces.Items) == 1 {
                t.Fatal("no other namespace")
            return ctx
    // test feature
    testenv.Test(t, f1, f2)

Running the test

Use the Go testing tooling to run the tests in the package as shown below. The following would run all tests except those with label type=ns-count:

go test ./package -args --skip-labels="type=ns-count"


See the ./examples directory for additional examples showing how to use the framework.
