Functions

func CompareBatches

func CompareBatches(t *testing.T, want, got *postage.Batch)

CompareBatches is a testing helper that compares two batches and fails the test if all fields are not equal. Fails on first different value and prints the comparison.

func CompareChainState

func CompareChainState(t *testing.T, want, got *postage.ChainState)

CompareChainState is a test helper that compares two ChainStates and fails the test if they are not exactly equal. Fails on first difference and returns a descriptive comparison.

func MustNewAddress

func MustNewAddress() []byte

MustNewAddress will generate a new random address (20 byte slice). Panics on errors.

func MustNewBatch

func MustNewBatch(opts ...BatchOption) *postage.Batch

MustNewBatch will create a new test batch. Fields that are not supplied will be filled with random data. Panics on errors.

func MustNewBatchStamp

func MustNewBatchStamp(batch []byte) *postage.Stamp

MustNewBatchStamp will generate a postage stamp with the provided batch ID and assign random data to other fields. Panics on error

func MustNewFields

func MustNewFields(batch []byte, index, ts uint64) *postage.Stamp

MustNewBatchStamp will generate a postage stamp with the provided batch ID and assign random data to other fields. Panics on error

func MustNewID

func MustNewID() []byte

MustNewID will generate a new random ID (32 byte slice). Panics on errors.

func MustNewSignature

func MustNewSignature() []byte

MustNewSignature will create a new random signature (65 byte slice). Panics on errors.

func MustNewStamp

func MustNewStamp() *postage.Stamp

MustNewStamp will generate a invalid postage stamp with random data. Panics on errors.

func MustNewStampWithTimestamp

func MustNewStampWithTimestamp(ts uint64) *postage.Stamp

MustNewStampWithTimestamp will generate a postage stamp with provided timestamp and random data for other fields. Panics on errors.

func MustNewValidSignature

func MustNewValidSignature(signer crypto.Signer, addr swarm.Address, id, index, timestamp []byte) []byte

MustNewValidSignature will create a new valid signature. Panics on errors.

func MustNewValidStamp

func MustNewValidStamp(signer crypto.Signer, addr swarm.Address) *postage.Stamp

MustNewValidStamp will generate a valid postage stamp with random data. Panics on errors.

func NewBigInt

func NewBigInt() *big.Int

NewBigInt will generate a new random big int (uint64 base value).

func NewChainState

func NewChainState() *postage.ChainState

NewChainState will create a new ChainState with random values.
