TestPing Initiates a ping test between a source container and network (1 ip) and a destination container and network (1 ip)

Functions

func BuildNetTestContext

func BuildNetTestContext(pods []*provider.Pod, aIPVersion netcommons.IPVersion, aType netcommons.IFType, logger *log.Logger) (netsUnderTest map[string]netcommons.NetTestContext)

func RunNetworkingTests

func RunNetworkingTests(
	netsUnderTest map[string]netcommons.NetTestContext,
	count int,
	aIPVersion netcommons.IPVersion,
	logger *log.Logger) (report testhelper.FailureReasonOut, skip bool)

runNetworkingTests takes a map netcommons.NetTestContext, e.g. one context per network attachment and runs pings test with it. Returns a network name to a slice of bad target IPs map.
