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, nodeID flow.Identifier, networkKey crypto.PrivateKey, sporkID flow.Identifier, logger zerolog.Logger, opts ...nodeOpt) p2p.LibP2PNode

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 EnsureNoPubsubExchangeBetweenGroups ¶

func EnsureNoPubsubExchangeBetweenGroups(t *testing.T, ctx context.Context, groupA []p2p.LibP2PNode, groupB []p2p.LibP2PNode, messageFactory func() (interface{}, channels.Topic))

EnsureNoPubsubExchangeBetweenGroups ensures that no pubsub message is exchanged between the given groups of nodes.

func EnsureNoPubsubMessageExchange ¶

func EnsureNoPubsubMessageExchange(t *testing.T, ctx context.Context, from []p2p.LibP2PNode, to []p2p.LibP2PNode, messageFactory func() (interface{}, channels.Topic))

EnsureNoPubsubMessageExchange ensures that the no pubsub message is exchanged "from" the given nodes "to" the given nodes.

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 EnsureNotConnectedBetweenGroups ¶

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

EnsureNotConnectedBetweenGroups ensures no connection exists between the given groups of 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 PeerIdFixture ¶

func PeerIdFixture(t *testing.T) peer.ID

PeerIdFixture creates a random and unique peer ID (libp2p node ID).

func PeerIdsFixture ¶

func PeerIdsFixture(t *testing.T, n int) []peer.ID

PeerIdsFixture creates random and unique peer IDs (libp2p node IDs).

func SilentNodeFixture ¶

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

SilentNodeFixture returns a TCP listener and a node which never replies

func SubMustNeverReceiveAnyMessage ¶

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