Ideally they would be in separate package. // Basic Usage: // Create a test app with NewTestApp, then all keepers and their methods can be accessed for test setup and execution. // Advanced Usage: // Some tests call for an app to be initialized with some state. This can be achieved through keeper method calls (ie keeper.SetParams(...)). // However this leads to a lot of duplicated logic similar to InitGenesis methods. // So TestApp.InitializeFromGenesisStates() will call InitGenesis with the default genesis state. // and TestApp.InitializeFromGenesisStates(authState, cdpState) will do the same but overwrite the auth and cdp sections of the default genesis state // Creating the genesis states can be combersome, but helper methods can make it easier such as NewAuthGenStateFromAccounts below. type TestApp struct { App } func NewTestApp() TestApp { config := sdk.GetConfig() SetBech32AddressPrefixes(config) SetBip44CoinType(config) db := tmdb.NewMemDB() app := NewApp(log.NewNopLogger(), db, nil, true, map[int64]bool{}, 0) return TestApp{App: *app} } // nolint func (tApp TestApp) GetAccountKeeper() auth.AccountKeeper { return tApp.accountKeeper } func (tApp TestApp) GetBankKeeper() bank.Keeper { return tApp.bankKeeper } func (tApp TestApp) GetSupplyKeeper() supply.Keeper { return tApp.supplyKeeper } func (tApp TestApp) GetStakingKeeper() staking.Keeper { return tApp.stakingKeeper } func (tApp TestApp) GetSlashingKeeper() slashing.Keeper { return tApp.slashingKeeper } func (tApp TestApp) GetMintKeeper() mint.Keeper { return tApp.mintKeeper } func (tApp TestApp) GetDistrKeeper() distribution.Keeper { return tApp.distrKeeper } func (tApp TestApp) GetGovKeeper() gov.Keeper { return tApp.govKeeper } func (tApp TestApp) GetCrisisKeeper() crisis.Keeper { return tApp.crisisKeeper } func (tApp TestApp) GetUpgradeKeeper() upgrade.Keeper { return tApp.upgradeKeeper } func (tApp TestApp) GetParamsKeeper() params.Keeper { return tApp.paramsKeeper } func (tApp TestApp) GetVVKeeper() validatorvesting.Keeper { return tApp.vvKeeper } func (tApp TestApp) GetAuctionKeeper() auction.Keeper { return tApp.auctionKeeper } func (tApp TestApp) GetCDPKeeper() cdp.Keeper { return tApp.cdpKeeper } func (tApp TestApp) GetPriceFeedKeeper() pricefeed.Keeper { return tApp.pricefeedKeeper } func (tApp TestApp) GetBep3Keeper() bep3.Keeper { return tApp.bep3Keeper } func (tApp TestApp) GetKavadistKeeper() kavadist.Keeper { return tApp.kavadistKeeper } func (tApp TestApp) GetIncentiveKeeper() incentive.Keeper { return tApp.incentiveKeeper } func (tApp TestApp) GetCommitteeKeeper() committee.Keeper { return tApp.committeeKeeper } func (tApp TestApp) GetIssuanceKeeper() issuance.Keeper { return tApp.issuanceKeeper } // This calls InitChain on the app using the default genesis state, overwitten with any passed in genesis states func (tApp TestApp) InitializeFromGenesisStates(genesisStates ...GenesisState) TestApp { // Create a default genesis state and overwrite with provided values genesisState := NewDefaultGenesisState() for _, state := range genesisStates { for k, v := range state { genesisState[k] = v } } // Initialize the chain stateBytes, err := codec.MarshalJSONIndent(tApp.cdc, genesisState) if err != nil { panic(err) } tApp.InitChain( abci.RequestInitChain{ Validators: []abci.ValidatorUpdate{}, AppStateBytes: stateBytes, }, ) tApp.Commit() tApp.BeginBlock(abci.RequestBeginBlock{Header: abci.Header{Height: tApp.LastBlockHeight() + 1}}) return tApp } // InitializeFromGenesisStatesWithTime calls InitChain on the app using the default genesis state, overwitten with any passed in genesis states and genesis Time func (tApp TestApp) InitializeFromGenesisStatesWithTime(genTime time.Time, genesisStates ...GenesisState) TestApp { // Create a default genesis state and overwrite with provided values genesisState := NewDefaultGenesisState() for _, state := range genesisStates { for k, v := range state { genesisState[k] = v } } // Initialize the chain stateBytes, err := codec.MarshalJSONIndent(tApp.cdc, genesisState) if err != nil { panic(err) } tApp.InitChain( abci.RequestInitChain{ Time: genTime, Validators: []abci.ValidatorUpdate{}, AppStateBytes: stateBytes, }, ) tApp.Commit() tApp.BeginBlock(abci.RequestBeginBlock{Header: abci.Header{Height: tApp.LastBlockHeight() + 1}}) return tApp } func (tApp TestApp) CheckBalance(t *testing.T, ctx sdk.Context, owner sdk.AccAddress, expectedCoins sdk.Coins) { acc := tApp.GetAccountKeeper().GetAccount(ctx, owner) require.NotNilf(t, acc, "account with address '%s' doesn't exist", owner) require.Equal(t, expectedCoins, acc.GetCoins()) } // Create a new auth genesis state from some addresses and coins.
