Functions

func CopyConnectionAndClientToPath

func CopyConnectionAndClientToPath(path *ibctesting.Path, pathToCopy *ibctesting.Path) *ibctesting.Path

In ibctesting, there's no easy way to create a new channel on an existing connection To get around this, this helper function will copy the client/connection info from an existing channel We use this when creating ICA channels, because we want to reuse the same connections/clients from the transfer channel

func CreateRandomAccounts

func CreateRandomAccounts(numAccts int) []sdk.AccAddress

Generate random account addresss

func NewIcaPath

func NewIcaPath(chainA *ibctesting.TestChain, chainB *ibctesting.TestChain) *ibctesting.Path

Creates an ICA channel between two chains

func NewTransferPath

func NewTransferPath(chainA *ibctesting.TestChain, chainB *ibctesting.TestChain) *ibctesting.Path

Creates a transfer channel between two chains
