Functions ¶

func WithBlockGasLimit ¶

func WithBlockGasLimit(gaslimit uint64) func(ethConf *ethconfig.Config)

WithBlockGasLimit configures the simulated backend to target a specific gas limit when producing blocks.

func WithCallGasLimit ¶

func WithCallGasLimit(gaslimit uint64) func(ethConf *ethconfig.Config)

WithCallGasLimit configures the simulated backend to cap eth_calls to a specific gas limit when running client operations.

Types ¶

type Backend ¶

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

Backend is a simulated blockchain for testing.

func NewBackend ¶

func NewBackend(alloc types.GenesisAlloc, options ...func(*ethconfig.Config)) *Backend

NewBackend creates a new simulated backend.

func (*Backend) AdjustTime ¶

func (b *Backend) AdjustTime(adjustment time.Duration) error

AdjustTime changes the block timestamp.

func (*Backend) Client ¶

func (b *Backend) Client() Client

Client returns the underlying client.

func (*Backend) Close ¶

func (b *Backend) Close() error

Close shuts down the backend.

func (*Backend) Commit ¶

func (b *Backend) Commit(accept bool) common.Hash

Commit seals a block and moves the chain forward.

func (*Backend) Fork ¶

func (b *Backend) Fork(parentHash common.Hash) error

Fork creates a side-chain for reorg testing.

func (*Backend) Rollback ¶

func (b *Backend) Rollback()

Rollback removes all pending transactions.

type Client ¶

type Client interface {
	bind.ContractBackend
	Close()
	ChainID(context.Context) (*big.Int, error)
	BlockByNumber(context.Context, *big.Int) (*types.Block, error)
	BlockNumber(context.Context) (uint64, error)
	HeaderByHash(context.Context, common.Hash) (*types.Header, error)
	HeaderByNumber(context.Context, *big.Int) (*types.Header, error)
	TransactionReceipt(context.Context, common.Hash) (*types.Receipt, error)
	TransactionByHash(context.Context, common.Hash) (*types.Transaction, bool, error)
	BalanceAt(context.Context, common.Address, *big.Int) (*big.Int, error)
	NonceAt(context.Context, common.Address, *big.Int) (uint64, error)
	SuggestGasPrice(context.Context) (*big.Int, error)
	EstimateBaseFee(context.Context) (*big.Int, error)
}

Client exposes the methods provided by the Ethereum RPC client.
