Functions

func AddTestAddrs 

func AddTestAddrs(app *SimApp, 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 AppStateFn 

func AppStateFn(cdc *codec.Codec, simManager *module.SimulationManager) simtypes.AppStateFn

AppStateFn returns the initial application state using a genesis or the simulation parameters. It panics if the user provides files for both of them. If a file is not given for the genesis or the sim params, it creates a randomized one.

func AppStateFromGenesisFileFn 

func AppStateFromGenesisFileFn(r io.Reader, cdc *codec.Codec, genesisFile string) (tmtypes.GenesisDoc, []simtypes.Account)

AppStateFromGenesisFileFn util function to generate the genesis AppState from a genesis.json file.

func AppStateRandomizedFn 

func AppStateRandomizedFn(
	simManager *module.SimulationManager, r *rand.Rand, cdc *codec.Codec,
	accs []simtypes.Account, genesisTimestamp time.Time, appParams simtypes.AppParams,
) (json.RawMessage, []simtypes.Account)

AppStateRandomizedFn creates calls each module's GenesisState generator function and creates the simulation params

func CheckBalance 

func CheckBalance(t *testing.T, app *SimApp, 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 CreateTestPubKeys 

func CreateTestPubKeys(numPubKeys int) []crypto.PubKey

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

func GenSequenceOfTxs 

func GenSequenceOfTxs(msgs []sdk.Msg, accNums []uint64, initSeqNums []uint64, numToGenerate int, priv ...crypto.PrivKey) []auth.StdTx

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

func GetMaccPerms 

func GetMaccPerms() map[string][]string

GetMaccPerms returns a copy of the module account permissions

func MakeCodecs 

func MakeCodecs() (*std.Codec, *codec.Codec)

MakeCodecs constructs the *std.Codec and *codec.Codec instances used by simapp. It is useful for tests and clients who do not want to construct the full simapp

func NewAnteHandler 

func NewAnteHandler(
	ak auth.AccountKeeper, bankKeeper bank.Keeper, ibcKeeper ibc.Keeper,
	tk token.Keeper, sigGasConsumer ante.SignatureVerificationGasConsumer,
) sdk.AnteHandler

NewAnteHandler returns an AnteHandler that checks and increments sequence numbers, checks signatures & account numbers, and deducts fees from the first signer.

func NewPubKeyFromHex 

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

NewPubKeyFromHex returns a PubKey from a hex string.

func SignCheckDeliver 

func SignCheckDeliver(
	t *testing.T, cdc *codec.Codec, app *bam.BaseApp, header abci.Header, msgs []sdk.Msg,
	accNums, seq []uint64, expSimPass, expPass bool, priv ...crypto.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.

func TestAddr 

func TestAddr(addr string, bech string) (sdk.AccAddress, error)

Types

type GenerateAccountStrategy 

type GenerateAccountStrategy func(int) []sdk.AccAddress

type GenesisState 

type GenesisState map[string]json.RawMessage

The genesis state of the blockchain is represented here as a map of raw json messages key'd by a identifier string. The identifier is used to determine which module genesis information belongs to so it may be appropriately routed during init chain. Within this application default genesis information is retrieved from the ModuleBasicManager which populates json from each BasicModule object provided to it during init.

func NewDefaultGenesisState 

func NewDefaultGenesisState() GenesisState

NewDefaultGenesisState generates the default state for the application.

type SimApp 

type SimApp struct {
	*baseapp.BaseApp

	// keepers
	AccountKeeper    auth.AccountKeeper
	BankKeeper       bank.Keeper
	CapabilityKeeper *capability.Keeper
	StakingKeeper    staking.Keeper
	SlashingKeeper   slashing.Keeper
	MintKeeper       mint.Keeper
	DistrKeeper      distr.Keeper
	GovKeeper        gov.Keeper
	CrisisKeeper     crisis.Keeper
	UpgradeKeeper    upgrade.Keeper
	ParamsKeeper     params.Keeper
	IBCKeeper        *ibc.Keeper // IBC Keeper must be a pointer in the app, so we can SetRouter on it correctly
	EvidenceKeeper   evidence.Keeper
	TransferKeeper   transfer.Keeper
	TokenKeeper      token.Keeper
