smartest

Local SmartWeave simulation

Usage

• smartest.readContractState(contractId)
  • Read state from env
• smartest.writeContractState(contractId, state)
  • Write state to env
• await smartest.interactWrite(arweave, contractSrc, wallet, contractInput, contractState, walletAddress, contractId, contractOwner=null)
  • Execute contract and write state to env

Example

// import smartest
const smartest = require("@_koi/smartest");

// set the initial state
const tallyInitState = JSON.parse(
    fs.readFileSync(`test/tally_init_state.json`)
);
smartest.writeContractState(tallyContractId, tallyInitState);

// Load tally contract and prepare input
const tallySrc = fs.readFileSync(`test/tally.js`, "utf8");
const tallyContractId = "q5w6e7r8";
const tallyInput = {
    function: "tally",
    rngContractId: rngContractId
};

// Interact write contract
await smartest.interactWrite(
    arweave,
    tallySrc,
    wallet,
    tallyInput,
    smartest.readContractState(tallyContractId),
    walletAddress,
    tallyContractId
);

// Inspect output
console.log(smartest.readContractState(tallyContractId));

Testing

node test path/to/wallet.json

Notes

• Smartest is locked to SmartWeave 0.4.31 or earlier as later versions use arweave.blocks.getCurrent() in interactWriteDryRun which breaks smartest
