Functions

func RequireGenericNodesDoneBefore

func RequireGenericNodesDoneBefore(t testing.TB, duration time.Duration, nodes ...*GenericNode)

RequireGenericNodesDoneBefore invokes the done method of all input generic nodes concurrently, and fails the test if any generic node's shutdown takes longer than the specified duration.
