我想在单元测试中获取一个JSON文件，因为我需要在测试中使用它，但是我不知道如何包含该文件

我用业力和茉莉花进行测试。我的项目是使用Angular 2创建的。

我的JSON文件的名称是'www/assets/mocks/emptyCalendarData.JSON'。

有人知道我如何将JSON文件包含到规范文件中吗？

谢谢

更新

我尝试使用HTTP get，但是我得到了一个系统

let calendarData: Calendar;
http.get('www/assets/mocks/emptyCalendarData.json')
    .map(res => res.json())
    .subscribe(
        data => calendarData = data,
        err => console.log(JSON.stringify(err))
    );

然后我得到这个错误：

ERROR: Error{stack: null, originalErr: TypeError{stack: 'mergeOptions
get
