foundry-zksync-coverage-demo

This repository demonstrates an issue with test coverage generation (forge coverage --zksync) in the zkSync environment, where the regular EVM is used instead of the expected zkEVM. The project contains a simple contract with one test that verifies the address of a deployed contract using CREATE, and it shows that forge coverage --zksync for zkSync runs using EVM instead of zkEVM.

How to Reproduce

To reproduce the issue, run the following commands:

1. Run zkSync tests:

   yarn test:zksync -vvvv
   

2. Run zkSync test coverage:

   yarn coverage:zksync -vvvv
   

   The logs will show that the regular EVM is being used instead of zkEVM, and new Empty() created with EVM.

Screenshots

In the logs above and in the screenshots of these logs, you can see that the regular EVM is used in coverage mode instead of zkEVM, demonstrating the issue.
