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
	_ "github.com/koordinator-sh/koordinator/test/e2e/common/network"
	_ "github.com/koordinator-sh/koordinator/test/e2e/common/node"
	_ "github.com/koordinator-sh/koordinator/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 "github.com/onsi/ginkgo"

// SIGDescribe annotates the test with the SIG label.
func SIGDescribe(text string, body func()) bool {
	return ginkgo.Describe("[sig-cluster-lifecycle] "+text, body)
}

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

package bootstrap

import (
	"github.com/onsi/ginkgo"
	"github.com/koordinator-sh/koordinator/test/e2e/lifecycle"
)
var _ = lifecycle.SIGDescribe("[Feature:BootstrapTokens]", func() {
  /* ... */
  ginkgo.It("should sign the new added bootstrap tokens", func() {
    /* ... */
  })
  /* 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

Functions

func AfterSuiteActions

func AfterSuiteActions()

AfterSuiteActions are actions that are run on ginkgo's SynchronizedAfterSuite

func CleanupSuite

func CleanupSuite()

CleanupSuite is the boilerplate that can be used after tests on ginkgo were run, on the SynchronizedAfterSuite step. Similar to SynchronizedBeforeSuite, we want to run some operations only once (such as collecting cluster logs). Here, the order of functions is reversed; first, the function which runs everywhere, and then the function that only runs on the first Ginkgo node.

func RunE2ETests

func RunE2ETests(t *testing.T)

RunE2ETests checks configuration parameters (specified through flags) and then runs E2E tests using the Ginkgo runner. If a "report directory" is specified, one or more JUnit test reports will be generated in this directory, and cluster logs will also be saved. This function is called on each Ginkgo node in parallel mode.
