Question

我无法在nodejs上顺利进行茉莉花测试。我的意思是，有些情况下测试只是在运行过程中停止，没有通知任何东西，但是默默地失败了。我刚才得到的一个例子是：

在validater.validateIDs中。有一个回调＆＃34; isOkFunc＆＃34;被发送到另一个模块的函数到自定义的mongoose.find-function

validateIDs = function (data, dbFunc) {
        data = data || selfData;

        var
            isOkFunc = (function () {
                var ret = {};
                ret.thisData = void 0;

                ret.setData = function (data) {
                    ret.thisData = (data === undefined) ? true : data;
                };
                return ret;
            })(),
            findData = {
                playerID: data.playerID,
                gameID: data.gameID,
                turnID: data.turnID,
                objectID: data.objectID
            };

        dbFunc.find(findData, isOkFunc.setData);
        return isOkFunc.thisData;
    };

在自定义查找函数中调用回调函数：

this.find = function (data, cb) {
    models.Order.find(data,function (err, orders) {
        if (err) {
            console.log("error in getting orders");
            cb(void 0);
        } else {
            console.log(orders);
            cb(orders);
        }
    });
};

既然我忘了将thisData指向ret.thisData，那就错了，因为变量不存在。但问题是茉莉花没有通知任何关于此的事情，它只是默默地失败并停止执行。如何更好地进行调试呢？或者更像是如何进行实际调试？

导致问题的spec文件中的实际部分是：

isOk = validater.validateIDs(data, orderReceive);

剥离几个不相关的descibe-sections后，这是整个spec-file：

"use strict";
/* This is for making jasmine testing work in windows with netbeans. If this 
 * causes trouble for you, then try to find a better solution. I need this in 
 * windows enviroment */

    require("jasmine-node");
};

    orders = require("../../databases/modules/orders.js"),
    orderReceive = orders.ordersAtDatabase("../testDB"),
    data, UUID = uuid.v4();;

/* Counts the amount of finished-class received. When it reaches given point. 
 * Executes all functions. This is supposed to be executed last to remove database entries

var toExecuteLast = (function toExecuteLast() {
    var funcs = [], ret = {}, i,
        count = 0,
        max = 5;

    ret.add = function(func) {
        funcs.push(func);
    };
    ret.finished = function() {
        count++;
    };
    ret.do = function() {
        console.log("gogogo");
        if(count >= max) {
            console.log("gogogo2222");
            for(i = 0; i < funcs.length; i++) {
                funcs[i]();
            }
            clearInterval(toExecuteLast.do);
        }
    };

    return ret;
})();
