func CollectionNode ¶

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

CollectionNode returns a mock collection node.

func CompleteStateFixture ¶ added in v0.14.0

func CompleteStateFixture(
	t testing.TB,
	log zerolog.Logger,
	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.
