Functions

func IsRateLimitedPeerFilter added in v0.30.0 

func IsRateLimitedPeerFilter(rateLimiter p2p.RateLimiter) p2p.PeerFilter

IsRateLimitedPeerFilter returns a p2p.PeerFilter that will return an error if the peer is rate limited.

func LibP2PNodeForNetworkFixture added in v0.32.0 

func LibP2PNodeForNetworkFixture(t *testing.T, sporkId flow.Identifier, n int, opts ...p2ptest.NodeFixtureParameterOption) (flow.IdentityList, []p2p.LibP2PNode)

LibP2PNodeForNetworkFixture is a test helper that generate flow identities with a valid port and libp2p nodes. Note that the LibP2PNode created by this fixture is meant to used with a network component. If you want to create a standalone LibP2PNode without network component, please use p2ptest.NodeFixture. Args: 

t: testing.T- the test object
sporkId: flow.Identifier - the spork id to use for the nodes
n: int - number of nodes to create

opts: []p2ptest.NodeFixtureParameterOption - options to configure the nodes Returns: 

flow.IdentityList - list of identities created for the nodes, one for each node.

[]p2p.LibP2PNode - list of libp2p nodes created. TODO: several test cases only need a single node, consider encapsulating this function in a single node fixture.

func MisbehaviorReportFixture added in v0.31.0 

func MisbehaviorReportFixture(t *testing.T) network.MisbehaviorReport

func NetworkPayloadFixture 

func NetworkPayloadFixture(t *testing.T, size uint) []byte

func NewRateLimiterConsumer(callback func(pid peer.ID, role, msgType, topic, reason string)) p2p.RateLimiterConsumer

NewRateLimiterConsumer returns a p2p.RateLimiterConsumer fixture that will invoke the callback provided.

func OptionalSleep(send ConduitSendWrapperFunc)

OptionalSleep introduces a sleep to allow nodes to heartbeat and discover each other (only needed when using PubSub)

func StartNetworks added in v0.31.0 

func StartNetworks(ctx irrecoverable.SignalerContext, t *testing.T, nets []network.EngineRegistry)

StartNetworks starts the provided networks using the provided irrecoverable context Arguments: - ctx: the irrecoverable context to use for starting the networks. - t: the test object. - nets: the networks to start. - duration: the timeout to use for waiting for the networks to start.

This function fails the test if the networks do not start within the given timeout.

func StartNodes 

func StartNodes(ctx irrecoverable.SignalerContext, t *testing.T, nodes []p2p.LibP2PNode)

StartNodes starts the provided nodes and their peer managers using the provided irrecoverable context

func StartNodesAndNetworks 

func StartNodesAndNetworks(ctx irrecoverable.SignalerContext, t *testing.T, nodes []p2p.LibP2PNode, nets []network.EngineRegistry)

StartNodesAndNetworks starts the provided networks and libp2p nodes, returning the irrecoverable error channel. Arguments: - ctx: the irrecoverable context to use for starting the nodes and networks. - t: the test object. - nodes: the libp2p nodes to start. - nets: the networks to start. - timeout: the timeout to use for waiting for the nodes and networks to start.

This function fails the test if the nodes or networks do not start within the given timeout.

func StopComponents 

func StopComponents[R module.ReadyDoneAware](t *testing.T, rda []R, duration time.Duration)

StopComponents stops ReadyDoneAware instances in parallel and fails the test if they could not be stopped within the duration.

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
