Patrick Ohly e3ee4e3585 e2e: replace klog.Fatal with assertion
Using klog.Fatal to abort a test leads to a poor user experience because the
output is buffered in ginkgo.GinkgoWriter and not flushed before killing the
process. The output is also different from other failures. Using the normal
error checking is better.

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
