Functions

func CheckBalances 

func CheckBalances(
	t *testing.T,
	ctx sdk.Context,
	bankKeeper bankkeeper.WrappedBankKeeper,
	address sdk.AccAddress,
	expected sdk.Coins,
)

func CheckErrorf 

func CheckErrorf(t *testing.T, err error, errType error, msg string, a ...interface{})

CheckErrorf checks whether - error type is wrapped inside the given error - error match given message string combined with error type

func GenTx added in v2.2.0 

func GenTx(
	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 MustGetBalances 

func MustGetBalances(ctx sdk.Context, bankKeeper bankkeeper.WrappedBankKeeper, address sdk.AccAddress) sdk.Coins

func ParseTime 

func ParseTime(t int64) time.Time

ParseTime is a helper function to parse from number to time.Time with UTC locale.

func SignAndDeliver 

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

SignAndDeliver signs and delivers a transaction. No simulation occurs as the ibc testing package causes checkState and deliverState to diverge in block time.

func Wasm56 

func Wasm56(time int) []byte

EXECUTE:
  Loop for `time` times and set return data "new beeb".

func Wasm78 

func Wasm78(time int) []byte

An oracle script to test large calldata 

PREPARE:
  Ask external data with calldata "b"*time
EXECUTE:
  Return with data "b"*time
