使用jasmine测试骨干关系模型

Question

假设我有两个简单的fixture文件,一个用于用户(1),另一个用于消息(2).

消息的骨干模型如下(3).

如果我加载"消息夹具",我想在消息模型中指定有关用户的相关信息.
使用jasmine测试套件在规范视图(4)中激活此目标的正确方法是什么？
有关详细信息,请参阅(4)中的注释.

// User Fixture
beforeEach(function () {
    this.fixtures = _.extend(this.fixtures || {}, {
        Users: {
            valid: {
                status: 'OK',
                version: '1.0',
                response: {
                    users: [
                        {
