Documentation

networkId :: NetworkId Source #

data Dataset Source #

A Dataset that can be run for testing purpose. Each Dataset represents a complete scenario where several ClientDataset are run concurrently against one or more HydraNodes. A dataset can optionally have a title and description which will be used to report results.

defaultProtocolParameters :: PParams LedgerEra Source #

generateConstantUTxODataset Source #

Arguments

:: SigningKey PaymentKey	Faucet signing key
-> Int	Number of clients
-> Int	Number of transactions
-> Gen Dataset

Generate a Dataset which does not grow the per-client UTXO set over time. This version provided faucet key owns funds on the initial funds of the devnet (See availableInitialFunds and 'genesis-shelley.json'). Then for a given number of clients a number of transactions are generated.

generateDemoUTxODataset Source #

Arguments

:: NetworkId
-> SocketPath
-> SigningKey PaymentKey	Faucet signing key
-> Int	Number of clients.
-> Int	Number of transactions
-> IO Dataset

Generate a Dataset from an already running network by quering available funds of the well-known 'faucet.sk' and assuming the hydra-nodes we connect to have fuel available. Then for a given number of clients a number of transactions are generated.
