func (chain *TestChain) QueryUpgradeProof(key []byte, height uint64) ([]byte, clienttypes.Height)

QueryUpgradeProof performs an abci query with the given key and returns the proto encoded merkle proof for the query and the height at which the proof will succeed on a tendermint verifier.

func (*TestChain) RawQuery added in v0.41.0

func (chain *TestChain) RawQuery(contractAddr string, queryData []byte) ([]byte, error)

func (*TestChain) SeedNewContractInstance

func (chain *TestChain) SeedNewContractInstance() sdk.AccAddress

SeedNewContractInstance stores some wasm code and instantiates a new contract on this chain. This method can be called to prepare the store with some valid CodeInfo and ContractInfo. The returned Address is the contract address for this instance. Test should make use of this data and/or use NewIBCContractMockWasmEngine for using a contract mock in Go.

func (*TestChain) SendMsgs

func (chain *TestChain) SendMsgs(msgs ...sdk.Msg) (*abci.ExecTxResult, error)

SendMsgs delivers a transaction through the application. It updates the senders sequence number and updates the TestChain's headers. It returns the result and error if one occurred.

func (*TestChain) SendNonDefaultSenderMsgs added in v0.30.0

func (chain *TestChain) SendNonDefaultSenderMsgs(senderPrivKey cryptotypes.PrivKey, msgs ...sdk.Msg) (*abci.ExecTxResult, error)

SendNonDefaultSenderMsgs is the same as SendMsgs but with a custom signer/account

func (*TestChain) SmartQuery

func (chain *TestChain) SmartQuery(contractAddr string, queryMsg, response interface{}) error

SmartQuery This will serialize the query message and submit it to the contract. The response is parsed into the provided interface. Usage: SmartQuery(addr, QueryMsg{Foo: 1}, &response)

func (*TestChain) StoreCode

func (chain *TestChain) StoreCode(byteCode []byte) types.MsgStoreCodeResponse

func (*TestChain) StoreCodeFile

func (chain *TestChain) StoreCodeFile(filename string) types.MsgStoreCodeResponse

func (*TestChain) UnwrapExecTXResult added in v0.50.0

func (chain *TestChain) UnwrapExecTXResult(r *abci.ExecTxResult, target proto.Message)

UnwrapExecTXResult is a helper to unpack execution result from proto any type
