Warum erhalte ich nach dem Trüffeltest nicht „5 bestanden, 1 nicht bestanden“?

Nach dem Ausführen truffle testerhalte ich den folgenden unerwarteten Fehler:

Zanes-iMac:riskxtoken zanemassey$ truffle test

Ich hatte erwartet, dass 5 bestanden 1 fehlschlägt und der Vertrag mit den richtigen Werten + einem Assertionsfehler für den Crowdsale-Vertrag initialisiert wird:

pragma solidity ^0.4.23;

import "./RiskxToken.sol";

contract RiskxTokenSale {
    address admin;
    RiskxToken public tokenContract;

    function RiskxTokenSale(RiskxToken _tokenContract) public {
        admin = msg.sender;
        tokenContract = _tokenContract; 
        // Token contract
        // Token Price
    }
}

Dies ist mein Token-Vertrag:

pragma solidity ^0.4.23;

contract RiskxToken {
    string  public name = "Riskx Token";
    string  public symbol = "RIX";
    string  public standard = "Riskx Token v1.0";
    uint256 public totalSupply;

    event Transfer(
        address indexed _from,
        address indexed _to,
        uint256 _value
    );

    event Approval(
        address indexed _owner,
        address indexed _spender,
        uint256 _value
    );

    mapping(address => uint256) public balanceOf;
    mapping(address => mapping(address => uint256)) public allowance;

    function RiskxToken (uint256 _initialSupply) public {
        balanceOf[msg.sender] = _initialSupply;
        totalSupply = _initialSupply;
    }

    function transfer(address _to, uint256 _value) public returns (bool success) {
        require(balanceOf[msg.sender] >= _value);

        balanceOf[msg.sender] -= _value;
        balanceOf[_to] += _value;

        Transfer(msg.sender, _to, _value);

        return true;
    }

    function approve(address _spender, uint256 _value) public returns (bool success) {
        allowance[msg.sender][_spender] = _value;

        Approval(msg.sender, _spender, _value);

        return true;
    }

    function transferFrom(address _from, address _to, uint256 _value) public returns (bool success) {
        require(_value <= balanceOf[_from]);
        require(_value <= allowance[_from][msg.sender]);

        balanceOf[_from] -= _value;
        balanceOf[_to] += _value;

        allowance[_from][msg.sender] -= _value;

        Transfer(_from, _to, _value);

        return true;
    }
}

Ich versuche in diesem Stadium nichts zu emittieren, ich versuche nur, den Test zum Scheitern zu bringen. Weiß jemand, warum dies geschieht?
