I’m trying to call the below contract in the test file:

const RefundEscrow = artifacts.require('./RefundEscrow');

But I get the following error:

Error: Could not find artifacts for ./RefundEscrow from any sources

Noting that the RefundEscrow.sol file is exist in @OpenZeppelin\contracts\payment\escrow

I think it should be

const RefundEscrow = artifacts.require('RefundEscrow');

If you have a contract RefundEscrow

A little weird, how about truffle compile --force and then run this script?

I’m having the same issue:

‘Error: Could not find artifacts for .\RefundEscrow from any sources’

I’ve also tried removing the ‘./’, prefixing with ‘payments/’, etc.

Is there any resolution to this?

Note, the require statement is in a test.js file in my project.

Hi: welcome! :wave:

So what does your test file look like?

#12

And what does your test file look like?

#13

I’d like to call out my unfamiliarity with the tech stack. The code is adapted from a tutorial from late 2018, back when the package was ‘openzeppelin-solidity’, and RefundableCrowdsale used a ‘RefundVault’. It looks like openzeppelin has evolved a bit since then. I am attempting to do the tutorial with more updated packages. The below snippet is from the top section of the test file:

import ether from './helpers/ether'
import EVMRevert from './helpers/EVMRevert';

const { latestTime } = require('./helpers/latestTime');
const { increaseTimeTo, duration } = require('./helpers/increaseTime');
const BN = web3.utils.BN;

require('chai')
  .use(require('chai-bn')(BN))
  .use(require('chai-as-promised'))
  .should();

const MyToken = artifacts.require('MyToken');
const MyTokenCrowdsale = artifacts.require('MyTokenCrowdsale');
const RefundEscrow = artifacts.require('./RefundEscrow');

contract('MyTokenCrowdsale', function([_, wallet, investor1, investor2]) {
#14

How about change it to

const RefundEscrow = artifacts.require('RefundEscrow');
#15

Tried that. It didn’t work.

Hi, I just had a test at my local environment, maybe you can have a look, all is good in my side.
