Functions

func SetFeatureGateDuringTest

func SetFeatureGateDuringTest(t *testing.T, gate feature.FeatureGate, feature feature.Feature, value bool) func()

SetFeatureGateDuringTest sets the specified gate to the specified value, and returns a function that restores the original value. Failures to set or restore cause the test to fail.

Example use:

defer utilfeaturetesting.SetFeatureGateDuringTest(t, utilfeature.DefaultFeatureGate, features.<FeatureName>, true)()

func VerifyFeatureGatesUnchanged

func VerifyFeatureGatesUnchanged(gate feature.FeatureGate, tests func() int)

VerifyFeatureGatesUnchanged ensures the provided gate does not change any values when tests() are completed. Intended to be placed into unit test packages that mess with feature gates.

Example use:

import (

"testing"

utilfeature "k8s.io/apiserver/pkg/util/feature"
utilfeaturetesting "k8s.io/apiserver/pkg/util/feature/testing"
_ "k8s.io/kubernetes/pkg/features"

)

func TestMain(m *testing.M) {
  utilfeaturetesting.VerifyFeatureGatesUnchanged(utilfeature.DefaultFeatureGate, m.Run)
}
