func HackDenebMaxuint 

func HackDenebMaxuint(t *testing.T) func()

HackDenebMaxuint is helpful for tests that need to set up cases where the deneb fork has passed. We have unit tests that assert our config matches the upstream config, where the next fork is always set to MaxUint64 until the fork epoch is formally set. This creates an issue for tests that want to work with slots that are defined to be after deneb because converting the max epoch to a slot leads to multiplication overflow. Monkey patching tests with this function is the simplest workaround in these cases.

func NewBlindedBeaconBlockCapellaV2() *v2.SignedBlindedBeaconBlockCapella

NewBlindedBeaconBlockCapellaV2 creates a blinded beacon block with minimum marshalable fields.

func NewBlindedBeaconBlockDeneb 

func NewBlindedBeaconBlockDeneb() *ethpb.SignedBlindedBeaconBlockDeneb

NewBlindedBeaconBlockDeneb creates a blinded beacon block with minimum marshalable fields.

func PrepareRoots 

func PrepareRoots(size int) ([][]byte, error)

PrepareRoots returns a list of roots with hex representations of natural numbers starting with 0. Example: 16 becomes 0x00...0f.

func RandaoReveal 

func RandaoReveal(beaconState state.ReadOnlyBeaconState, epoch primitives.Epoch, privKeys []bls.SecretKey) ([]byte, error)

RandaoReveal returns a signature of the requested epoch using the beacon proposer private key.

func Random32Bytes 

func Random32Bytes(t *testing.T) []byte

Random32Bytes generates a random 32 byte slice.

func SaveBlock 

func SaveBlock(tb assertions.AssertionTestingTB, ctx context.Context, db iface.NoHeadAccessDatabase, b interface{}) interfaces.SignedBeaconBlock

func WaitTimeout 

func WaitTimeout(wg *sync.WaitGroup, timeout time.Duration) bool

WaitTimeout will wait for a WaitGroup to resolve within a timeout interval. Returns true if the waitgroup exceeded the timeout.

Types

type BlockGenConfig 

type BlockGenConfig struct {
	NumProposerSlashings uint64
	NumAttesterSlashings uint64
	NumAttestations      uint64
	NumDeposits          uint64
	NumVoluntaryExits    uint64
	NumTransactions      uint64 // Only for post Bellatrix blocks
	FullSyncAggregate    bool
	NumBLSChanges        uint64 // Only for post Capella blocks
}

BlockGenConfig is used to define the requested conditions for block generation.

func DefaultBlockGenConfig 

func DefaultBlockGenConfig() *BlockGenConfig

DefaultBlockGenConfig returns the block config that utilizes the current params in the beacon config.

type DenebBlockGeneratorOption 

type DenebBlockGeneratorOption func(*denebBlockGenerator)

func WithProposerSigning 

func WithProposerSigning(idx primitives.ValidatorIndex, sk bls.SecretKey, valRoot []byte) DenebBlockGeneratorOption

type NewBeaconStateOption 

type NewBeaconStateOption func(state *ethpb.BeaconState) error

type Waiter 

type Waiter struct {
	// contains filtered or unexported fields
}

Waiter offers an alternate ux for building tests that want to ensure contexts are used in certain ways.

func NewWaiter 

func NewWaiter() *Waiter

NewWaiter internally create the chan that Waiter relies on.

func (*Waiter) Done 

func (w *Waiter) Done()

Done is used with RequireDoneAfter and RequireDoneBefore to make assertions that certain test code is reached before a timeout or context cancellation.

func (*Waiter) RequireDoneAfter 

func (w *Waiter) RequireDoneAfter(t *testing.T, timeout time.Duration)

RequireDoneAfter forces the test to fail if the timeout is reached before Done is called.

func (*Waiter) RequireDoneBeforeCancel 

func (w *Waiter) RequireDoneBeforeCancel(ctx context.Context, t *testing.T)

RequireDoneBeforeCancel forces the test to fail if the context is cancelled before Done is called.
