智能合约代码：

function mintWhitelist() external {
        uint256 totalMinted = totalSupply();
        require(totalMinted < MAX, "All minted");

        uint256 whitelistAmount = whitelistNumber[msg.sender];
        require(whitelistAmount > 0, "Not in whitelist");
...
    }

测试代码：

    function test_mintWhitelist() public {
        vm.mockCall(
            address(addrContract),
            abi.encodeWithSelector(contract.totalSupply.selector),
            abi.encode(MAX)
        );
        assertEq(Contract.totalSupply(), MAX);

        vm.expectRevert("All minted");
        vm.prank(USER3);
        contract.mintWhitelist();
    }

测试结果：

[FAIL. Reason: Error != expected error: Not in whitelist != All minted] test_mintWhitelist_Part1() (gas: 18900)

从 Trace 可以看到，totalSupply() 已经变成了 10000，可是为什么测试到 mint 函数的时候，没有报 All minted 错误呢？
