var ErrPodCompleted = fmt.Errorf("pod ran to completion")

ErrPodCompleted is returned by PodRunning or PodContainerRunning to indicate that the pod has already reached completed state.

Functions

func AllNodesReady 

func AllNodesReady(c clientset.Interface, timeout time.Duration) error

Checks whether all registered nodes are ready. TODO: we should change the AllNodesReady call in AfterEach to WaitForAllNodesHealthy, and figure out how to do it in a configurable way, as we can't expect all setups to run default test add-ons.

func CreateTestingNS 

func CreateTestingNS(baseName string, c clientset.Interface, labels map[string]string) (*v1.Namespace, error)

CreateTestingNS should be used by every test, note that we append a common prefix to the provided test name. Please see NewFramework instead of using this directly.
