func TestReachableHTTPWithRetriableErrorCodes(host string, port int, retriableErrCodes []int, timeout time.Duration)
TestReachableHTTPWithRetriableErrorCodes tests that the given host serves HTTP on the given port with the given retriableErrCodes.
func UpdateService(c clientset.Interface, namespace, serviceName string, update func(*v1.Service)) (*v1.Service, error)
UpdateService fetches a service, calls the update function on it, and then attempts to send the updated service. It retries up to 2 times in the face of timeouts and conflicts.
WaitForServiceDeletedWithFinalizer waits for the service with finalizer to be deleted.
func WaitForServiceUpdatedWithFinalizer(cs clientset.Interface, namespace, name string, hasFinalizer bool)
WaitForServiceUpdatedWithFinalizer waits for the service to be updated to have or don't have a finalizer.

AddRCAntiAffinity adds AntiAffinity to the given ReplicationController.
ChangeServiceNodePort changes node ports of the given service.
ChangeServiceType updates the given service's ServiceType to the given newType.
CheckServiceReachability ensures that request are served by the services. Only supports Services with type ClusterIP, NodePort and ExternalName.
CreateExternalNameService creates a new ExternalName type Service based on the j's defaults. Callers can provide a function to tweak the Service object before it is created.
func (j *TestJig) CreateLoadBalancerService(timeout time.Duration, tweak func(svc *v1.Service)) (*v1.Service, error)
CreateLoadBalancerService creates a loadbalancer service and waits for it to acquire an ingress IP.
func (j *TestJig) CreateOnlyLocalLoadBalancerService(timeout time.Duration, createPod bool, tweak func(svc *v1.Service)) (*v1.Service, error)
CreateOnlyLocalLoadBalancerService creates a loadbalancer service with ExternalTrafficPolicy set to Local and waits for it to acquire an ingress IP. If createPod is true, it also creates an RC with 1 replica of the standard netexec container used everywhere in this test.
CreateOnlyLocalNodePortService creates a NodePort service with ExternalTrafficPolicy set to Local and sanity checks its nodePort. If createPod is true, it also creates an RC with 1 replica of the standard netexec container used everywhere in this test.

CreateTCPServiceWithPort creates a new TCP Service with given port based on the j's defaults. Callers can provide a function to tweak the Service object before it is created.
CreateTCPUDPServicePods creates a replication controller with the label same as service. Service listens to TCP and UDP.
CreateUDPService creates a new UDP Service based on the j's defaults. Callers can provide a function to tweak the Service object before it is created.
GetEndpointNodeNames returns a string set of node names on which the endpoints of the given Service are running.
GetEndpointNodes returns a map of nodenames:external-ip on which the endpoints of the Service are running.
func (j *TestJig) Run(tweak func(rc *v1.ReplicationController)) (*v1.ReplicationController, error)
Run creates a ReplicationController and Pod(s) and waits for the Pod(s) to be running. Callers can provide a function to tweak the RC object before it is created.
Scale scales pods to the given replicas
UpdateService fetches a service, calls the update function on it, and then attempts to send the updated service. It tries up to 3 times in the face of timeouts and conflicts.
WaitForEndpointOnNode waits for a service endpoint on the given node.
