feat(cheatcodes): add vm.chisel() to load chisel session from test function #4171
Description
Component
Chisel
Describe the feature you would like
This feature would introduce the possibility to add a call such as vm.chisel() or vm.chiselBreakpoint() anywhere in a test function.
The desired behavior is that calling chisel on that function will result in the session being loaded with the entire state of the test at the time the call was made, including the storage state as well as the memory.
Running forge test should not result in a different behavior than usual.
Example
pragma solidity ^0.8.15;
import "forge-std/Test.sol";
import "forge-std/console.sol";
import "src/Kevin.sol";
contract KevinTest is Test {
Kevin public kevin;
function setUp() public {
kevin = new Kevin();
}
function testKevin() public {
uint256 bob = 15;
vm.chisel();
uint256 stewart = 1;
}
}Followed by chisel --match testKevin, which opens up a chisel session.
