javascript - 使用 jasmine 测试 Backbone 关系模型

Question

假设我有两个简单的固定文件，一个用于用户 (1)，一个用于消息 (2)。

消息的 Backbone 模型如下 (3)。

如果我加载“Message Fixture”，我还想获得有关消息模型中指定的用户的相关信息。
使用 jasmine 测试套件在规范 View (4) 中激活此目标的正确方法是什么？
详情请见(4)中的评论。

// User Fixture
beforeEach(function () {
    this.fixtures = _.extend(this.fixtures || {}, {
        Users: {
            valid: {
                status: 'OK',
                version: '1.0',
                response: {
                    users: [
                        {
                            id: 1,
                            name: 'olivier'
                        },
                        {
                            id: 2,
                            name: 'pierre',
                        },
                        {
                            id: 3,
                            name: 'george'
                        }
                    ]
                }
            }
        }

// Message model
