Variables

var Forks = map[string]*params.ChainConfig{
	"Frontier": {
		ChainID: big.NewInt(1),
	},
	"EIP155": {
		ChainID:     big.NewInt(1),
		EIP155Block: big.NewInt(0),
	},
}

Forks table defines supported forks and their chain config.

Functions

func MakePreState

func MakePreState(db ethdb.Database, accounts core.GenesisAlloc, snapshotter bool) (*snapshot.Tree, *state.StateDB)

Types

type BlockTest

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

A BlockTest checks handling of entire blocks.

func (*BlockTest) Run

func (t *BlockTest) Run(snapshotter bool) error

func (*BlockTest) UnmarshalJSON

func (t *BlockTest) UnmarshalJSON(in []byte) error

UnmarshalJSON implements json.Unmarshaler interface.

type RLPTest

type RLPTest struct {
	// If the value of In is "INVALID" or "VALID", the test
	// checks whether Out can be decoded into a value of
	// type interface{}.
	//
	// For other JSON values, In is treated as a driver for
	// calls to rlp.Stream. The test also verifies that encoding
	// In produces the bytes in Out.
	In interface{}

	// Out is a hex-encoded RLP value.
	Out string
}

RLPTest is the JSON structure of a single RLP test.

func (*RLPTest) Run

func (t *RLPTest) Run() error

Run executes the test.

type StateSubtest

type StateSubtest struct {
	Fork  string
	Index int
}

StateSubtest selects a specific configuration of a General State Test.

type StateTest

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

StateTest checks transaction processing without block context. See https://github.com/ethereum/EIPs/issues/176 for the test format specification.

func (*StateTest) Run

func (t *StateTest) Run(subtest StateSubtest, vmconfig vm.Config, snapshotter bool) (*snapshot.Tree, *state.StateDB, error)

Run executes a specific subtest and verifies the post-state and logs

func (*StateTest) RunNoVerify

func (t *StateTest) RunNoVerify(subtest StateSubtest, vmconfig vm.Config, snapshotter bool) (*snapshot.Tree, *state.StateDB, common.Hash, error)

RunNoVerify runs a specific subtest and returns the statedb and post-state root

func (*StateTest) Subtests

func (t *StateTest) Subtests() []StateSubtest

Subtests returns all valid subtests of the test.

func (*StateTest) UnmarshalJSON

func (t *StateTest) UnmarshalJSON(in []byte) error

type TransactionTest

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

TransactionTest checks RLP decoding and sender derivation of transactions.

func (*TransactionTest) Run

func (tt *TransactionTest) Run(config *params.ChainConfig) error

type UnsupportedForkError

type UnsupportedForkError struct {
	Name string
}

UnsupportedForkError is returned when a test requests a fork that isn't implemented.

func (UnsupportedForkError) Error

func (e UnsupportedForkError) Error() string

type VMTest

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

VMTest checks EVM execution without block or transaction context. See https://github.com/ethereum/tests/wiki/VM-Tests for the test format specification.

func (*VMTest) Run

func (t *VMTest) Run(vmconfig vm.Config, snapshotter bool) error

func (*VMTest) UnmarshalJSON

func (t *VMTest) UnmarshalJSON(data []byte) error
