Functions

func CollectionNode

func CollectionNode(t *testing.T, hub *stub.Hub, identity *flow.Identity, identities []*flow.Identity, chainID flow.ChainID, options ...func(protocol.State)) testmock.CollectionNode

CollectionNode returns a mock collection node.

func CollectionNodes

func CollectionNodes(t *testing.T, hub *stub.Hub, nNodes int, chainID flow.ChainID, options ...func(protocol.State)) []testmock.CollectionNode

CollectionNodes returns n collection nodes connected to the given hub.

func CompleteStateFixture

func CompleteStateFixture(t testing.TB, log zerolog.Logger, metric *metrics.NoopCollector, tracer module.Tracer,
	participants flow.IdentityList) *testmock.StateFixture

CompleteStateFixture is a test helper that creates, bootstraps, and returns a StateFixture for sake of unit testing.

func ConsensusNode

func ConsensusNode(t *testing.T, hub *stub.Hub, identity *flow.Identity, identities []*flow.Identity, chainID flow.ChainID) testmock.ConsensusNode

func ConsensusNodes

func ConsensusNodes(t *testing.T, hub *stub.Hub, nNodes int, chainID flow.ChainID) []testmock.ConsensusNode

func ExecutionNode

func ExecutionNode(t *testing.T, hub *stub.Hub, identity *flow.Identity, identities []*flow.Identity, syncThreshold int, chainID flow.ChainID) testmock.ExecutionNode

func GenericNode

func GenericNode(t testing.TB, hub *stub.Hub, identity *flow.Identity, participants []*flow.Identity, chainID flow.ChainID,
	options ...func(protocol.State)) testmock.GenericNode

GenericNode is a test helper that creates and returns a generic node. The generic node is used as the core data structure to create other types of flow nodes.

func GenericNodeWithStateFixture

func GenericNodeWithStateFixture(t testing.TB,
	stateFixture *testmock.StateFixture,
	hub *stub.Hub,
	identity *flow.Identity,
	log zerolog.Logger,
	metrics *metrics.NoopCollector,
	tracer module.Tracer,
	chainID flow.ChainID) testmock.GenericNode

GenericNodeWithStateFixture is a test helper that creates a generic node with specified state fixture.

func VerificationNode

func VerificationNode(t testing.TB,
	hub *stub.Hub,
	identity *flow.Identity,
	identities []*flow.Identity,
	assigner module.ChunkAssigner,
	requestInterval time.Duration,
	processInterval time.Duration,
	receiptsLimit uint,
	chunksLimit uint,
	failureThreshold uint,
	chainID flow.ChainID,
	collector module.VerificationMetrics,
	mempoolCollector module.MempoolMetrics,
	opts ...VerificationOpt) testmock.VerificationNode
