func ExpectNoError 

func ExpectNoError(err error, explain ...interface{})

func ExpectNoErrorWithOffset 

func ExpectNoErrorWithOffset(offset int, err error, explain ...interface{})

ExpectNoErrorWithOffset checks if "err" is set, and if so, fails assertion while logging the error at "offset" levels above its caller (for example, for call chain f -> g -> ExpectNoErrorWithOffset(1, ...) error would be logged for "f").

func Failf 

func Failf(format string, args ...interface{})

func FailfWithOffset 

func FailfWithOffset(offset int, format string, args ...interface{})

FailfWithOffset calls "Fail" and logs the error at "offset" levels above its caller (for example, for call chain f -> g -> FailfWithOffset(1, ...) error would be logged for "f").

func GetPodCondition 

func GetPodCondition(status *v1.PodStatus, conditionType v1.PodConditionType) (int, *v1.PodCondition)

GetPodCondition extracts the provided condition from the given status and returns that. Returns nil and -1 if the condition is not present, and the index of the located condition.

func GetPodReadyCondition 

func GetPodReadyCondition(status v1.PodStatus) *v1.PodCondition
