Functions ¶

func SetFeatureGateDuringTest ¶

func SetFeatureGateDuringTest(tb TB, gate featuregate.FeatureGate, f featuregate.Feature, value bool)

SetFeatureGateDuringTest sets the specified gate to the specified value for duration of the test. Fails when it detects second call to the same flag or is unable to set or restore feature flag. When disabling a feature, this automatically disables all dependents.

WARNING: Can leak set variable when called in test calling t.Parallel(), however second attempt to set the same feature flag will cause fatal.

Example use:

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

func SetFeatureGateEmulationVersionDuringTest ¶

func SetFeatureGateEmulationVersionDuringTest(tb TB, gate featuregate.FeatureGate, ver *version.Version)

featuregatetesting.SetFeatureGateEmulationVersionDuringTest(t, utilfeature.DefaultFeatureGate, version.MustParse("1.31"))

func SetFeatureGateVersionsDuringTest ¶

func SetFeatureGateVersionsDuringTest(tb TB, gate featuregate.FeatureGate, emuVer, minCompatVer *version.Version)

featuregatetesting.SetFeatureGateVersionsDuringTest(t, utilfeature.DefaultFeatureGate, version.MustParse("1.31"), version.MustParse("1.31"))

func SetFeatureGatesDuringTest ¶

func SetFeatureGatesDuringTest(tb TB, gate featuregate.FeatureGate, features FeatureOverrides)

SetFeatureGatesDuringTest sets the specified map of feature gate values for duration of the test. Fails when it detects second call to the same flag or is unable to set or restore feature flag. When disabling a feature, this automatically disables all dependents that weren't explicitly set.

WARNING: Can leak set variable when called in test calling t.Parallel(), however second attempt to set the same feature flag will cause fatal.

Example use:

featuregatetesting.SetFeatureGatesDuringTest(t, utilfeature.DefaultFeatureGate, featuregatetesting.FeatureOverrides{
	features.<FeatureName>: true,
    features.<FeatureName>: false,
})
