test/e2e

This is home to e2e tests used for presubmit, periodic, and postsubmit jobs.

Some of these jobs are merge-blocking, some are release-blocking.

e2e test ownership

All e2e tests must adhere to the following policies:

• the test must be owned by one and only one SIG
• the test must live in/underneath a sig-owned package matching pattern: test/e2e/[{subpath}/]{sig}/..., e.g.
  • test/e2e/auth - all tests owned by sig-auth
  • test/e2e/common/storage - all tests common to cluster-level and node-level e2e tests, owned by sig-node
  • test/e2e/upgrade/apps - all tests used in upgrade testing, owned by sig-apps
• each sig-owned package should have an OWNERS file defining relevant approvers and labels for the owning sig, e.g.

# test/e2e/node/OWNERS
# See the OWNERS docs at https://go.k8s.io/owners

approvers:
- alice
- bob
- cynthia
emeritus_approvers:
- dave
reviewers:
- sig-node-reviewers
labels:
- sig/node

• packages that use {subpath} should have an imports.go file importing sig-owned packages (for ginkgo's benefit), e.g.

// test/e2e/common/imports.go
package common

import (
	// ensure these packages are scanned by ginkgo for e2e tests
	_ "k8s.io/kubernetes/test/e2e/common/network"
	_ "k8s.io/kubernetes/test/e2e/common/node"
	_ "k8s.io/kubernetes/test/e2e/common/storage"
)

• test ownership must be declared via a top-level SIGDescribe call defined in the sig-owned package, e.g.

// test/e2e/lifecycle/framework.go
package lifecycle

import "k8s.io/kubernetes/test/e2e/framework"

// SIGDescribe annotates the test with the SIG label.
var SIGDescribe = framework.SIGDescribe("cluster-lifecycle")

// test/e2e/lifecycle/bootstrap/bootstrap_signer.go

package bootstrap

import (
	"github.com/onsi/ginkgo"
	"k8s.io/kubernetes/test/e2e/lifecycle"
)
var _ = lifecycle.SIGDescribe("cluster", feature.BootstrapTokens, func() {
  /* ... */
  ginkgo.It("should sign the new added bootstrap tokens", func(ctx context.Context) {
    /* ... */
  })
  /* etc */
})

These polices are enforced:

• via the merge-blocking presubmit job pull-kubernetes-verify
• which ends up running hack/verify-e2e-test-ownership.sh
• which can also be run via make verify WHAT=e2e-test-ownership
