Functions

func AccountFixture added in v0.23.5 

func AccountFixture() (*flow.Account, error)

AccountFixture returns a randomly generated account.

func AccountKeyDefaultFixture added in v0.15.0 

func AccountKeyDefaultFixture() (*flow.AccountPrivateKey, error)

AccountKeyDefaultFixture returns a randomly generated ECDSA/SHA3 account key.

func AccountKeyFixture 

func AccountKeyFixture(
	seedLength int,
	signingAlgo crypto.SigningAlgorithm,
	hashAlgo hash.HashingAlgorithm,
) (*flow.AccountPrivateKey, error)

AccountKeyFixture returns a randomly generated account key.

func AddCollectionsToBlock added in v0.33.19 

func AddCollectionsToBlock(block *flow.Block, collections []*flow.Collection)

func AddVersionBeacon added in v0.31.0 

func AddVersionBeacon(t *testing.T, beacon *flow.VersionBeacon, state protocol.FollowerState)

AddVersionBeacon adds blocks sequence with given VersionBeacon so this service events takes effect in Flow protocol. This means execution result where event was emitted is sealed, and the seal is finalized by a valid block. This assumes state is bootstrapped with a root block, as it does NOT produce results for final block of the state Root <- A <- B(result(A(VB))) <- C(seal(B))

func AddressFixture 

func AddressFixture() flow.Address

func AreNumericallyClose added in v0.33.1 

func AreNumericallyClose(a, b float64, epsilon float64) bool

AreNumericallyClose returns true if the two floats are within epsilon of each other. The epsilon is calculated as: 

epsilon = max(|a|, |b|) * epsilon

Example: 

AreNumericallyClose(1.0, 1.1, 0.1) // true since 1.0 * 0.1 = 0.1 < 0.1
AreNumericallyClose(1.0, 1.1, 0.01) // false since 1.0 * 0.01 = 0.01 < 0.1
AreNumericallyClose(1.0, 1.1, 0.11) // false since 1.1 * 0.11 = 0.121 > 0.1

Args: a: the first float b: the second float epsilon: the epsilon value Returns: true if the two floats are within epsilon of each other false otherwise

ER(X) := ExecutionReceipt for block X S(ER(X)) := Seal for the ExecutionResult contained in ER(X) (seals block X)

A is the latest finalized block. Every block contains a receipt for the previous block and a seal for the receipt contained in the previous block. The only exception is when A is the root block, in which case block B does not contain a receipt for block A, and block C does not contain a seal for block A. This is because the root block is sealed from genesis, and we can't insert duplicate seals.

D contains a seal for block B containing the EpochSetup service event, processing D causes the EpochSetup to become activated.

F contains a seal for block D containing the EpochCommit service event. processing F causes the EpochCommit to become activated.

To build a sequence of epochs, we call BuildEpoch, then CompleteEpoch, and so on.

Upon building an epoch N (preparing epoch N+1), we store some information about the heights of blocks in the BUILT epoch (epoch N). These can be queried with EpochHeights.
