func GetAvailableLocalAddress

func GetAvailableLocalAddress(t *testing.T) string

GetAvailableLocalAddress finds an available local port and returns an endpoint describing it. The port is available for opening when this function returns provided that there is no race by some other code to grab the same port immediately.

func GetAvailablePort

func GetAvailablePort(t *testing.T) uint16
