Functions

func ChunkWithIndex 

func ChunkWithIndex(blockID flow.Identifier, index int) *flow.Chunk

func ContainerBlockFixture 

func ContainerBlockFixture(parent *flow.Header, receipts []*flow.ExecutionReceipt) *flow.Block

ContainerBlockFixture builds and returns a block that contains input execution receipts.

func CreateExecutionResult 

func CreateExecutionResult(blockID flow.Identifier, options ...func(result *flow.ExecutionResult, assignments *chunks.Assignment)) (*flow.ExecutionResult, *chunks.Assignment)

func EvenChunkIndexAssigner 

func EvenChunkIndexAssigner(index uint64, chunkNum int) bool

EvenChunkIndexAssigner is a helper function that returns true for the even indices in [0, chunkNum-1] It also returns true if the index corresponds to the system chunk.

func ExecutionResultForkFixture added in v0.23.2 

func ExecutionResultForkFixture(t *testing.T) (*flow.ExecutionResult, *flow.ExecutionResult, *flow.Collection, *flow.Block)

ExecutionResultForkFixture creates two conflicting execution results out of the same block ID. Each execution result has two chunks. First chunks of both results are the same, i.e., have same ID. It returns both results, their shared block, and collection corresponding to their first chunk.

func ExtendStateWithFinalizedBlocks 

func ExtendStateWithFinalizedBlocks(t *testing.T, completeExecutionReceipts CompleteExecutionReceiptList,
	state protocol.MutableState) []*flow.Block

ExtendStateWithFinalizedBlocks is a test helper to extend the execution state and return the list of blocks. It receives a list of complete execution receipt fixtures in the form of (R1,1 <- R1,2 <- ... <- C1) <- (R2,1 <- R2,2 <- ... <- C2) <- ..... Where R and C are the reference and container blocks. Reference blocks contain guarantees, and container blocks contain execution receipt for their preceding reference blocks, e.g., C1 contains receipts for R1,1, R1,2, etc. Note: for sake of simplicity we do not include guarantees in the container blocks for now.

func FromChunkID 

func FromChunkID(chunkID flow.Identifier) flow.ChunkDataPack

func MockChunkAssignmentFixture 

func MockChunkAssignmentFixture(chunkAssigner *mock.ChunkAssigner,
	verIds flow.IdentityList,

	isAssigned ChunkAssignerFunc) (flow.IdentifierList, flow.IdentifierList)

MockChunkAssignmentFixture is a test helper that mocks a chunk assigner for a set of verification nodes for the execution results in the given complete execution receipts, and based on the given chunk assigner function.

It returns the list of chunk locator ids assigned to the input verification nodes, as well as the list of their chunk IDs. All verification nodes are assigned the same chunks.

func MockLastSealedHeight 

func MockLastSealedHeight(state *mockprotocol.State, height uint64)

MockLastSealedHeight mocks the protocol state for the specified last sealed height.

func NewVerificationHappyPathTest added in v0.17.1 

func NewVerificationHappyPathTest(t *testing.T,

	retry int,
	ops ...CompleteExecutionReceiptBuilderOpt)

func RespondChunkDataPackRequestImmediately added in v0.17.6 

func RespondChunkDataPackRequestImmediately(t *testing.T,
	completeERs CompleteExecutionReceiptList,

	provider MockChunkDataProviderFunc) (*enginemock.GenericNode,
	*mocknetwork.Engine, *sync.WaitGroup)

SetupChunkDataPackProvider creates and returns an execution node that only has a chunk data pack provider engine.

The mock chunk provider engine replies the chunk back requests by invoking the injected provider method. All chunk data pack requests should come from a verification node, and should has one of the assigned chunk IDs. Otherwise, it fails the test.

func SetupMockConsensusNode 

func SetupMockConsensusNode(t *testing.T,
	log zerolog.Logger,
	hub *stub.Hub,
	conIdentity *flow.Identity,
	verIdentities flow.IdentityList,

	chainID flow.ChainID,
	assignedChunkIDs flow.IdentifierList) (*enginemock.GenericNode, *mocknetwork.Engine, *sync.WaitGroup)

SetupMockConsensusNode creates and returns a mock consensus node (conIdentity) and its registered engine in the network (hub). It mocks the process method of the consensus engine to receive a message from a certain verification node (verIdentity) evaluates whether it is a result approval about an assigned chunk to that verifier node.

func WithAssignee 

func WithAssignee(assignee flow.Identifier) func(flow.Identifier, uint64, *chunks.Assignment) *flow.Chunk

func WithChunks 

func WithChunks(setAssignees ...func(flow.Identifier, uint64, *chunks.Assignment) *flow.Chunk) func(*flow.ExecutionResult, *chunks.Assignment)

Types

type ChunkAssignerFunc 

type ChunkAssignerFunc func(chunkIndex uint64, chunks int) bool

type CompleteExecutionReceipt 

type CompleteExecutionReceipt struct {
	ContainerBlock *flow.Block // block that contains execution receipt of reference block

	// TODO: this is a temporary field to support finder engine logic
	// It should be removed once we replace finder engine.
	Receipts     []*flow.ExecutionReceipt // copy of execution receipts in container block
	ReceiptsData []*ExecutionReceiptData  // execution receipts data of the container block
}

CompleteExecutionReceipt is a test helper struct that represents a container block accompanied with all data required to verify its execution receipts. TODO update this as needed based on execution requirements

func CompleteExecutionReceiptChainFixture 

func CompleteExecutionReceiptChainFixture(t *testing.T, root *flow.Header, count int, opts ...CompleteExecutionReceiptBuilderOpt) []*CompleteExecutionReceipt

CompleteExecutionReceiptChainFixture is a test fixture that creates a chain of blocks of size `count`. The chain is in the form of root <- R1,1 <- R1,2 <- ... <- C1 <- R2,1 <- R2,2 <- ... <- C2 <- ... In this chain R refers to reference blocks that contain guarantees. C refers to a container block that contains an execution receipt for its preceding reference blocks. e.g., C1 contains an execution receipt for R1,1, R1,2, etc, and C2 contains a receipt for R2,1, R2,2, etc. For sake of simplicity and test, container blocks (i.e., C) do not contain any guarantee.
