func NewTestChain 

func NewTestChain(t *testing.T, coord *Coordinator, chainID string) TestChainI

NewTestChain initializes a new TestChain instance with a single validator set using a generated private key. It also creates a sender account to be used for delivering transactions.

The first block height is committed to state in order to allow for client creations on counterparty chains. The TestChain will return with a block height starting at 2.

Time management is handled by the Coordinator in order to ensure synchrony between chains. Each update of any chain increments the block header time for all chains by 5 seconds.

func SetupTestingApp 

func SetupTestingApp() (TestingApp, map[string]json.RawMessage)

func SetupWithGenesisValSet 

func SetupWithGenesisValSet(t *testing.T, chainId string, valSet *tmtypes.ValidatorSet, genAccs []authexported.GenesisAccount, balances ...sdk.Coins) TestingApp

SetupWithGenesisValSet initializes a new SimApp with a validator set and genesis accounts that also act as delegators. For simplicity, each validator is bonded with a delegation of one consensus engine unit (10^6) in the default token of the simapp from first genesis account. A Nop logger is set in SimApp.
