Can I assert the reason a call is reverted?

[AlexDiru]

If I have a function in my contract

function doSomething(uint x) public view returns (uint) {
  require(x > 10, "x must be greater than 10");
  require(x < 12, "x must be less than 12");
  return x + 1;
}

In hardhat I am able to write a test which can assert which of the require messages caused the failure, something like:

await expect(doSomethingCall).to.be.revertedWith("x must be greater than 10")

But I've found no way to accomplish the same with Foundry, I can only detect whether a revert happens not why. Is there a way to do this?

It shows up in the logs when the tests fail so I'm sure there must be a way:

Running 6 tests for test/OraclePricePool.t.sol:OraclePricePoolTest

[PASS] testFail_ExchangeRate_PriceFeedStale_2() (gas: 21662)

vm.expectRevert("revertString");

will make sure to catch require(false, "revertString") or revert("revertString")

Awesome, thank you!
