Functions

func AddNodesToEachOthersPeerStore

func AddNodesToEachOthersPeerStore(t *testing.T, nodes []p2p.LibP2PNode, ids flow.IdentityList)

AddNodesToEachOthersPeerStore adds the dialing address of all nodes to the peer store of all other nodes. However, it does not connect them to each other.

func CreateNode

func CreateNode(t *testing.T, networkKey crypto.PrivateKey, sporkID flow.Identifier, logger zerolog.Logger, nodeIds flow.IdentityList, opts ...nodeOpt) p2p.LibP2PNode

TODO: this should be replaced by node fixture: https://github.com/onflow/flow-go/blob/master/network/p2p/test/fixtures.go

func EnsureMessageExchangeOverUnicast

func EnsureMessageExchangeOverUnicast(t *testing.T, ctx context.Context, nodes []p2p.LibP2PNode, inbounds []chan string, messageFactory func() string)

EnsureMessageExchangeOverUnicast ensures that the given nodes exchange arbitrary messages on through unicasting (i.e., stream creation). It fails the test if any of the nodes does not receive the message from the other nodes. The "inbounds" parameter specifies the inbound channel of the nodes on which the messages are received. The "messageFactory" parameter specifies the function that creates unique messages to be sent.

func EnsureNoStreamCreation

func EnsureNoStreamCreation(t *testing.T, ctx context.Context, from []p2p.LibP2PNode, to []p2p.LibP2PNode, errorCheckers ...func(*testing.T, error))

EnsureNoStreamCreation ensures that no stream is created "from" the given nodes "to" the given nodes.

func EnsureNoStreamCreationBetweenGroups

func EnsureNoStreamCreationBetweenGroups(t *testing.T, ctx context.Context, groupA []p2p.LibP2PNode, groupB []p2p.LibP2PNode, errorCheckers ...func(*testing.T, error))

EnsureNoStreamCreationBetweenGroups ensures that no stream is created between the given groups of nodes.

func EnsureNotConnected

func EnsureNotConnected(t *testing.T, ctx context.Context, from []p2p.LibP2PNode, to []p2p.LibP2PNode)

EnsureNotConnected ensures that no connection exists from "from" nodes to "to" nodes.

func EnsureStreamCreation

func EnsureStreamCreation(t *testing.T, ctx context.Context, from []p2p.LibP2PNode, to []p2p.LibP2PNode)

EnsureStreamCreation ensures that a stream is created between each of the "from" nodes to each of the "to" nodes.

func HasSubReceivedMessage

func HasSubReceivedMessage(t *testing.T, ctx context.Context, expectedMessage []byte, sub p2p.Subscription) bool

HasSubReceivedMessage checks that the subscription have received the given message within the given timeout by the context. It returns true if the subscription has received the message, false otherwise.

func LongStringMessageFactoryFixture

func LongStringMessageFactoryFixture(t *testing.T) func() string

LongStringMessageFactoryFixture returns a function that creates a long unique string message.

func MustEncodeEvent

func MustEncodeEvent(t *testing.T, v interface{}, channel channels.Channel) []byte

MustEncodeEvent encodes and returns the given event and fails the test if it faces any issue while encoding.

func NetworkingKeyFixtures

func NetworkingKeyFixtures(t *testing.T) crypto.PrivateKey

NetworkingKeyFixtures is a test helper that generates a ECDSA flow key pair.

func SilentNodeFixture

func SilentNodeFixture(t *testing.T) (net.Listener, flow.Identity)

SilentNodeFixture returns a TCP listener and a node which never replies

func SubMustEventuallyStopReceivingAnyMessage added in v0.33.30

func SubMustEventuallyStopReceivingAnyMessage(t *testing.T, ctx context.Context, sub p2p.Subscription, publish func(t *testing.T))

SubMustEventuallyStopReceivingAnyMessage checks that the subscription eventually stops receiving any messages within the given timeout by the context. This func uses the publish callback to continually publish messages to the subscription, this ensures that the subscription indeed stops receiving the messages.

func SubMustNeverReceiveAnyMessage

func SubMustNeverReceiveAnyMessage(t *testing.T, ctx context.Context, sub p2p.Subscription)

SubMustNeverReceiveAnyMessage checks that the subscription never receives any message within the given timeout by the context.

func SubMustReceiveMessage

func SubMustReceiveMessage(t *testing.T, ctx context.Context, expectedMessage []byte, sub p2p.Subscription)

SubMustReceiveMessage checks that the subscription have received the given message within the given timeout by the context.

func SubsMustEventuallyStopReceivingAnyMessage added in v0.33.30

func SubsMustEventuallyStopReceivingAnyMessage(t *testing.T, ctx context.Context, subs []p2p.Subscription, send func(t *testing.T))

func SubsMustNeverReceiveAnyMessage

func SubsMustNeverReceiveAnyMessage(t *testing.T, ctx context.Context, subs []p2p.Subscription)

SubsMustNeverReceiveAnyMessage checks that all subscriptions never receive any message within the given timeout by the context.

func SubsMustReceiveMessage

func SubsMustReceiveMessage(t *testing.T, ctx context.Context, expectedMessage []byte, subs []p2p.Subscription)

SubsMustReceiveMessage checks that all subscriptions receive the given message within the given timeout by the context.

func WithSubscriptionFilter

func WithSubscriptionFilter(filter pubsub.SubscriptionFilter) nodeOpt
