Bypass or troubleshoot SimTest

[RaulBernal]

My simulation test breaks with this message:

Simulating... block 1/500, operation 0/272. Logs to writing to /Users/raul/.simapp/simulations/2023-10-03_12:48:46.log

My unit test for check if a Bcnaid exists or not works. But I don't know how to make an exemption for a global test.
This is the code of the Simulation test:

func TestFullAppSimulation(t *testing.T) {

	simcli.FlagSeedValue = time.Now().Unix()
	simcli.FlagVerboseValue = true
	simcli.FlagCommitValue = true
	simcli.FlagEnabledValue = true

	config := simcli.NewConfigFromFlags()
	config.ChainID = "bitcanna-sim"

	db, dir, logger, skip, err := simtestutil.SetupSimulation(config, "leveldb-app-sim", "Simulation", simcli.FlagVerboseValue, simcli.FlagEnabledValue)
	if skip {
		t.Skip("skipping application simulation")
	}
	require.NoError(t, err, "simulation setup failed")

	defer func() {
		require.NoError(t, db.Close())
		require.NoError(t, os.RemoveAll(dir))
	}()

	appOptions := make(simtestutil.AppOptionsMap, 0)
	appOptions[flags.FlagHome] = app.DefaultNodeHome
	appOptions[server.FlagInvCheckPeriod] = simcli.FlagPeriodValue

	bApp := app.New(
		logger,
		db,
		nil,
		true,
		map[int64]bool{},
		app.DefaultNodeHome,
		0,
		app.MakeEncodingConfig(),
		appOptions,
		baseapp.SetChainID(config.ChainID),
	)
	require.Equal(t, app.Name, bApp.Name())

	// run randomized simulation
	_, simParams, simErr := simulation.SimulateFromSeed(
		t,
		os.Stdout,
		bApp.BaseApp,
		simtestutil.AppStateFn(
			bApp.AppCodec(),
			bApp.SimulationManager(),
			app.NewDefaultGenesisState(bApp.AppCodec()),
		),
		simulationtypes.RandomAccounts, // Replace with own random account function if using keys other than secp256k1
		simtestutil.SimulationOperations(bApp, bApp.AppCodec(), config),
		bApp.ModuleAccountAddrs(),
		config,
		bApp.AppCodec(),
	)

	// export state and simParams before the simulation error is checked
	err = simtestutil.CheckExportSimulation(bApp, config, simParams)
	require.NoError(t, err)
	require.NoError(t, simErr)

	if config.Commit {
		simtestutil.PrintStats(db)
	}
}

Hi @tac0turtle
do you know who could help here? Thanks

[tac0turtle]

we will look into this, we are also rewriting the simulator right now

[RaulBernal]

Should I keep this discussion opened or are you going to announce something?

[tac0turtle]

we will look into this for now to help with solving the issue
