Functions

func GenerateIDs

func GenerateIDs(t *testing.T, logger zerolog.Logger, n int, dryRunMode, connGating bool, opts ...func(*flow.Identity)) (flow.IdentityList, []*p2p.Node, []observable.Observable)

GenerateIDs is a test helper that generate flow identities with a valid port and libp2p nodes. If `dryRunMode` is set to true, it returns an empty slice instead of libp2p nodes, assuming that slice is never going to get used.

func GenerateIDsMiddlewaresNetworks

func GenerateIDsMiddlewaresNetworks(t *testing.T,
	n int,
	log zerolog.Logger,
	csize int,
	tops []network.Topology,

func GenerateNetworks

func GenerateNetworks(t *testing.T,
	log zerolog.Logger,
	ids flow.IdentityList,

	sms []network.SubscriptionManager,
	dryRunMode bool) []*p2p.Network

GenerateNetworks generates the network for the given middlewares

func GenerateSubscriptionManagers

func GenerateSubscriptionManagers(t *testing.T, mws []*p2p.Middleware) []network.SubscriptionManager

GenerateSubscriptionManagers creates and returns a ChannelSubscriptionManager for each middleware object.

func GenerateTopologies

func GenerateTopologies(t *testing.T, state protocol.State, identities flow.IdentityList, logger zerolog.Logger) []network.Topology

CreateTopologies is a test helper on receiving an identity list, creates a topology per identity and returns the slice of topologies.

Types

type ConduitSendWrapperFunc

type ConduitSendWrapperFunc func(msg interface{}, conduit network.Conduit, targetIDs ...flow.Identifier) error

ConduitSendWrapperFunc is a wrapper around the set of methods offered by the Conduit (e.g., Publish). This data type is solely introduced at the test level. Its primary purpose is to make the same test reusable on different Conduit methods.

type ConduitWrapper

type ConduitWrapper struct{}

func (*ConduitWrapper) Multicast

func (c *ConduitWrapper) Multicast(msg interface{}, conduit network.Conduit, targetIDs ...flow.Identifier) error

Multicast defines a function that receives a message, conduit of an engine instance, and a set of target ID. It then sends the message to the target IDs using the Multicast method of conduit.

func (*ConduitWrapper) Publish

func (c *ConduitWrapper) Publish(msg interface{}, conduit network.Conduit, targetIDs ...flow.Identifier) error

Publish defines a function that receives a message, conduit of an engine instance, and a set target IDs. It then sends the message to the target IDs using the Publish method of conduit.

func (*ConduitWrapper) Unicast

func (c *ConduitWrapper) Unicast(msg interface{}, conduit network.Conduit, targetIDs ...flow.Identifier) error

Unicast defines a function that receives a message, conduit of an engine instance, and a set of target IDs. It then sends the message to the target IDs using individual Unicasts to each target in the underlying network.

type EchoEngine

type EchoEngine struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

EchoEngine is a simple engine that is used for testing the correctness of driving the engines with libp2p, in addition to receiving and storing incoming messages it also echos them back
