Functions

func AppStateFn

func AppStateFn(cdc codec.Codec, simManager *module.SimulationManager, genesisState map[string]json.RawMessage) 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.JSONCodec, genesisFile string) (tmtypes.GenesisDoc, []simtypes.Account, error)

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,
	genesisState map[string]json.RawMessage,
) (json.RawMessage, []simtypes.Account)

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

func CheckExportSimulation

func CheckExportSimulation(app runtime.AppI, config simtypes.Config, params simtypes.Params) error

CheckExportSimulation exports the app state and simulation parameters to JSON if the export paths are defined.

func GetSimulatorFlags

func GetSimulatorFlags()

GetSimulatorFlags gets the values of all the available simulation flags

func NewConfigFromFlags

func NewConfigFromFlags() simulation.Config

NewConfigFromFlags creates a simulation from the retrieved values of the flags.

func PrintStats

func PrintStats(db dbm.DB)

PrintStats prints the corresponding statistics from the app DB.

func SimulationOperations

func SimulationOperations(app *milkyway.MilkyWayApp, cdc codec.JSONCodec, config simtypes.Config) []simtypes.WeightedOperation

SimulationOperations retrieves the simulation params from the provided file path and returns all the modules weighted operations
