Functions

func AddTestAddrs

func AddTestAddrs(myApp *app.App, ctx sdk.Context, accNum int, accAmt sdk.Int) []sdk.AccAddress

AddTestAddrs constructs and returns accNum amount of accounts with an initial balance of accAmt in random order

func AddTestAddrsFromPubKeys

func AddTestAddrsFromPubKeys(myApp *app.App, ctx sdk.Context, pubKeys []cryptotypes.PubKey, accAmt sdk.Int)

AddTestAddrsFromPubKeys adds the addresses into the SimApp providing only the public keys.

func AddTestAddrsIncremental

func AddTestAddrsIncremental(myApp *app.App, ctx sdk.Context, accNum int, accAmt sdk.Int) []sdk.AccAddress

func CheckBalance

func CheckBalance(t *testing.T, myApp *app.App, addr sdk.AccAddress, balances sdk.Coins)

CheckBalance checks the balance of an account.

func ConvertAddrsToValAddrs

func ConvertAddrsToValAddrs(addrs []sdk.AccAddress) []sdk.ValAddress

ConvertAddrsToValAddrs converts the provided addresses to ValAddress.

func CreateMultiEthKey

func CreateMultiEthKey(count int) []*ecdsa.PrivateKey

func CreateTestPubKeys

func CreateTestPubKeys(numPubKeys int) []cryptotypes.PubKey

CreateTestPubKeys returns a total of numPubKeys public keys in ascending order.

func DefGenesisState

func DefGenesisState(cdc codec.Codec) app.GenesisState

func GenSequenceOfTxs

func GenSequenceOfTxs(txGen client.TxConfig, msgs []sdk.Msg, accNums []uint64, initSeqNums []uint64, numToGenerate int, priv ...cryptotypes.PrivKey) ([]sdk.Tx, error)

GenSequenceOfTxs generates a set of signed transactions of messages, such that they differ only by having the sequence numbers incremented between every transaction.

func GenTx

func GenTx(r *rand.Rand, gen client.TxConfig, msgs []sdk.Msg, feeAmt sdk.Coins, gas uint64, chainID string, accNums, accSeqs []uint64, priv ...cryptotypes.PrivKey) (sdk.Tx, error)

GenTx generates a signed mock transaction.

func GenerateAddress

func GenerateAddress() common.Address

GenerateAddress generates an Ethereum address.

func GenerateEthAddress

func GenerateEthAddress() common.Address

func GenerateEthKey

func GenerateEthKey() *ecdsa.PrivateKey

func GenerateGenesisValidator

func GenerateGenesisValidator(validatorNum int, initCoins sdk.Coins) (valSet *tmtypes.ValidatorSet, genAccs authtypes.GenesisAccounts, balances []banktypes.Balance)

func NewEthPrivKey

func NewEthPrivKey() cryptotypes.PrivKey

NewEthPrivKey generates an Ethereum address and its corresponding private key.

func NewMnemonic

func NewMnemonic() string

func NewPriKey

func NewPriKey() cryptotypes.PrivKey

NewPriKey generates cosmos-sdk accAddress private key.

func NewPubKeyFromHex

func NewPubKeyFromHex(pk string) (res cryptotypes.PubKey)

NewPubKeyFromHex returns a PubKey from a hex string.

func NewSigner

func NewSigner(sk cryptotypes.PrivKey) keyring.Signer

func PrivKeyFromMnemonic

func PrivKeyFromMnemonic(mnemonic string, algo hd.PubKeyType, account, index uint32) (cryptotypes.PrivKey, error)

func Setup

func Setup(isCheckTx bool, isShowLog bool) *app.App

func SetupWithGenesisAccounts

func SetupWithGenesisAccounts(genAccs []authtypes.GenesisAccount, balances ...banktypes.Balance) *app.App

SetupWithGenesisAccounts initializes a new SimApp with the provided genesis accounts and possible balances.

func SetupWithGenesisValSet

func SetupWithGenesisValSet(t *testing.T, valSet *tmtypes.ValidatorSet, genAccs []authtypes.GenesisAccount, balances ...banktypes.Balance) *app.App

SetupWithGenesisValSet initializes a new SimApp with a validator set and genesis accounts that also act as delegators. For simplicity, each validator is bonded with a delegation of one consensus engine unit (10^6) in the default token of the simapp from first genesis account. A Nop logger is set in SimApp.

func SignCheckDeliver

func SignCheckDeliver(t *testing.T, txCfg client.TxConfig, app *baseapp.BaseApp, header tmproto.Header, msgs []sdk.Msg,
	chainID string, accNums, accSeqs []uint64, expSimPass, expPass bool, priv ...cryptotypes.PrivKey,
) (sdk.GasInfo, *sdk.Result, error)

SignCheckDeliver checks a generated signed transaction and simulates a block commitment with the given transaction. A test assertion is made using the parameter 'expPass' against the result. A corresponding result is returned.
