Events not emitted during tests

philipp · April 1, 2021, 4:38pm

I’m implementing OpenZeppelin’s PullPayment (4.0.0) contract.
Unfortunately, during testing I’m always getting AssertionError: Expected event "Deposited" to be emitted, but it wasn't Also the Withdrawn event doesn’t get emitted. But _asyncTransfer seems to run properly as Transfergets emitted.

I checked my ABI and it seems the contract is compiled correctly.

Environment
I’m using Hardhart with Waffle, Chai, Mocha, Ethers.js.

Code to reproduce
This is my contract
This is my test

Hi @philipp,

Welcome to the community

I am sorry that you are having this issue. Can you share a simple contract and test?

Perhaps similar to the following:

github.com

OpenZeppelin/openzeppelin-contracts/blob/v4.0.0/test/utils/escrow/Escrow.behavior.js#L30


});

it('only the owner can deposit', async function () {
  await expectRevert(this.escrow.deposit(payee1, { from: payee2 }),
    'Ownable: caller is not the owner',
  );
});

it('emits a deposited event', async function () {
  const { logs } = await this.escrow.deposit(payee1, { from: owner, value: amount });
  expectEvent.inLogs(logs, 'Deposited', {
    payee: payee1,
    weiAmount: amount,
  });
});

it('can add multiple deposits on a single account', async function () {
  await this.escrow.deposit(payee1, { from: owner, value: amount });
  await this.escrow.deposit(payee1, { from: owner, value: amount.muln(2) });

  expect(await balance.current(this.escrow.address)).to.be.bignumber.equal(amount.muln(3));

Hi @philipp -- I'm having the same problem. Did you ever figure out what it was? I tried looking at This is my test, but I got a 404 from github.

Ok, I figured it out. Events from other contracts are not in receipts. You have to use expectEvent.inTransaction instead of just expectEvent. Something like:

await expectEvent.inTransaction(receipt.tx, Escrow, 'Deposited', {payee: beneficiary, weiAmount: refund});

Where Escrow is the Escrow contract.
