Quickstart

How to write test for a sCrypt contract

The major steps to write a sCrypt test are exemplified by tests/demo.scrypttest.js.

import / require scrypttest libary.

import { buildContractClass } from 'scrypttest';

Use the imported function buildContractClass to get a reflected contract, which has same properties and methods as defined in the specified sCrypt contract.

const Demo = buildContractClass(path.join(__dirname, '../contracts/demo.scrypt'));

Initialize the contract.

demo = new Demo(4, 7);

Write tests for the instantiated contract as you would do in Javascript.

expect(demo.unlock(4 + 7)).to.equal(true);

How to run tests locally

Run using sCrypt Extension

Run unit tests file within the editor/explorer context menu.

Note: The test files must be suffixed by .scrypttest.js or .scrypttest.ts, otherwise the "Run sCrypt Test" option would not appear in the menu.

Run from console

Tests could also be run from the console by executing npm test, just like regular Javascript/TypeScript tests.

How to run tests remotely on testnet

When your tests succeed locally, you can run them on testnet.

Provide a private key with funds in tests/runontestnet.js

const key = ''

npm run testnet
