There was a problem hiding this comment. Using Are there any workarounds? Is it worth it to contribute to Hardhat to improve this? There was a problem hiding this comment. I once wrote an helper that is const getAddress = (account : string | { address: string }) : string => account.address ?? account;but calling it everywhere is even worst. Maybe it could be integrated by default ... There was a problem hiding this comment.
There was a problem hiding this comment. Note: I'd love to simplify the code by removing There was a problem hiding this comment. Agree with migrating using There was a problem hiding this comment. For anyone curious, this PR NomicFoundation/hardhat#4449 resolves the issue in hardhat-chai-matchers |

We could cache it in a global helper. But it should run only once per contract test suite anyway.

Do you know how this will behave with ethers?
Would it work if in the tests we do
this.accounts.shift()?There was a problem hiding this comment.

I was thinking in something like:

And we would get the signers as an argument of
contract("...", accounts => { ... });?
That makes sens, but it will also break the existing truffle tests, which we don't want.

Too maintenance heavy (and error prone) IMO.

If loadFixture does a "per contract suite" snapshot, I don't see why we would have to also do a "cross contract suite" snapshot. That is making everything slower, and I really don't see what it brings in exchange. The only usecase I see for that, is if we wanted our test to all start with
blockNumber = 0... and I don't think that is an assumption we should make. IMO our tests (each test.js file) should work regardless of the initial state of the chain.There was a problem hiding this comment.

Keeping the high-level snapshot makes sense if not all the contract suites implement a fixture. Let's try removing the high-level snapshot once we finish with the migration as well.
I like this, let's implement it that way 😄

Side note, I also added a comment in #4658 to keep track of things we should do to consolidate the migration once done
