// SetTestOnlyCBORClientFeatureGatesForTest overrides the CBOR client feature gates in the test-only
// client feature gate instance for the duration of a test. The CBOR client feature gates are
// temporarily registered in their own feature gate instance that does not include runtime wiring to
// command-line flags or environment variables in order to mitigate the risk of enabling a new
// encoding before all integration tests have been demonstrated to pass.
//
// This will be removed as an alpha requirement. The client feature gates will be registered with
// the existing feature gate instance and tests will use
// k8s.io/client-go/features/testing.SetFeatureDuringTest (which unlike
// k8s.io/component-base/featuregate/testing.SetFeatureGateDuringTest does not accept a feature gate
// instance as a parameter).

// EnableCBORForTest patches global state to enable the CBOR serializer and reverses those changes
// at the end of the test. As a risk mitigation, integration tests are initially written this way so
// that integration tests can be implemented fully and incrementally before exposing options
// (including feature gates) that can enable CBOR at runtime. After integration test coverage is
// complete, feature gates will be introduced to completely supersede this mechanism.
