Measure and report gas usage within forge tests
Add some reports to your forge tests
import { Test } from "forge-std/Test.sol";
import { GasReporter } from "@latticexyz/gas-report/src/GasReporter.sol";
contract ExampleTest is Test, GasReporter {
function testGas() public {
startGasReport("description of behavior to measure gas for");
// do something here
endGasReport();
}
}Then use the cli command to run tests and save the report:
pnpm gas-report --save gas-report.jsonOr, if you have your own test command, you can pipe the output to gas-report --stdin:
GAS_REPORTER_ENABLED=true forge test -vvv --isolate | pnpm gas-report --stdinRun pnpm gas-report --help for more details.
