Foundry also has the ability to report the gas used per function call which mimics the behavior of hardhat-gas-reporter. Generally speaking if gas costs per function call is very high, then the likelihood of its success is reduced. Gas optimization is an important activity done by smart contract developers.
Every poc in this repository can produce a gas report like this:
forge test --gas-report --contracts <contract> -vvvFor Example: Let us find out the gas used in the Audius poc
Execution
forge test --gas-report --contracts ./src/test/Audius.exp.sol -vvvDemo
