Functions

func CollectionNode 

func CollectionNode(t *testing.T, hub *stub.Hub, identity *flow.Identity, rootSnapshot protocol.Snapshot) testmock.CollectionNode

CollectionNode returns a mock collection node.

func CollectionNodes 

func CollectionNodes(t *testing.T, hub *stub.Hub, nNodes int) []testmock.CollectionNode

CollectionNodes returns n collection nodes connected to the given hub.

func CompleteStateFixture added in v0.14.0 

func CompleteStateFixture(
	t testing.TB,
	metric *metrics.NoopCollector,
	tracer module.Tracer,
	rootSnapshot protocol.Snapshot,
) *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,
	root protocol.Snapshot,
) testmock.GenericNode

GenericNode returns a generic test node, containing components shared across all node roles. The generic node is used as the core data structure to create other types of flow nodes.

func GenericNodeFromParticipants added in v0.20.0 

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

GenericNodeFromParticipants is a test helper that creates and returns a generic node. The generic node's state is generated from the given participants, resulting in a root state snapshot.

CAUTION: Please use GenericNode instead for most use-cases so that multiple nodes may share the same root state snapshot.

func GenericNodeWithStateFixture added in v0.14.0 

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 LocalFixture added in v0.15.4 

func LocalFixture(t testing.TB, identity *flow.Identity) module.Local

LocalFixture creates and returns a Local module for given identity.

func VerificationNode 

func VerificationNode(t testing.TB,
	hub *stub.Hub,
	verIdentity *flow.Identity,
	participants flow.IdentityList,
	assigner module.ChunkAssigner,
	chunksLimit uint,
	chainID flow.ChainID,
	collector module.VerificationMetrics,
	mempoolCollector module.MempoolMetrics,
	opts ...VerificationOpt) testmock.VerificationNode

VerificationNode creates a verification node with all functional engines and actual modules for purpose of (integration) testing.
