Question

我正在测试一个ember组件，该组件将调用一个返回promise的外部方法，并从导航器的URL对象调用createObjectURL：

var query = from d in model.StringDatas
        where d.DCString.DCDistributionBox.DataLogger.ProjectID == projectID
        where d.TimeStamp >= fromDate
        where d.TimeStamp < tillDate
        group d by DbFunctions.AddMinutes(DateTime.MinValue, DbFunctions.DiffMinutes(DateTime.MinValue, d.TimeStamp) / minuteInterval * minuteInterval) into g
        select new
        {
            TimeStamp = g.Key,
            DCCurrentMin = g.Min(v => v.DCCurrent / v.DCString.CurrentMPP),
            DCCurrentMax = g.Max(v => v.DCCurrent / v.DCString.CurrentMPP),
            DCCurrentAvg = g.Average(v => v.DCCurrent / v.DCString.CurrentMPP),
            DCCurrentStDev = DbFunctions.StandardDeviation(g.Select(v => v.DCCurrent / v.DCString.CurrentMPP))
        };

var queryResult= query.ToList();

但是，测试将始终返回：

    @fetch(@get 'self').then((blob) =>
      url = URL.createObjectURL blob
      @set 'url', url
    )

我尝试创建服务并注入它，创建一个对象并将其传递给 @subject（）方法，但仍然如此。有没有办法在ember测试中访问 chrome 浏览器的window.URL对象？

我刚刚在这里找到答案：Failed to execute 'createObjectURL' on 'URL':

我需要先创建一个blob，然后将其传递给 createObjectURL 函数。
