Using OpenZeppelin upgradable smart contracts with forge

[Ignacio-Freire]

Hello everyone,

I've been searching on the docs, issues and discussions for the last 2 days but I haven't been able to find anything related to this. So I decided to start a discussion and check if anyone was able to overcome this issue.

The project I'm working at has a central "controller" smart contract that is upgradable, so far we have 3 versions. While using hardhat in addition to the OpenZeppelin test-helpers, it's really easy to deploy the version 1 with all the parameters and then upgrade to version 3 while keeping all the data.

This is done by using deployProxy and then upgradeProxy.

I'm guessing the way to do this on Foundry could also be deploying the ProxyAdmin, the Proxy and the SC manually to later upgrade it.

I was wondering if there's anything similar to the test-helpers implemented with Foundry or if anyone has an example on how to do it.

Thanks a lot!
