使用Jasmine和Sinon测试骨干模型 - 对象#<Object>没有方法'spy'

Question

我正在尝试学习如何使用Jasmine和Sinon来测试Backbone应用程序,我正在学习本教程.然而,我遇到了一个我不知道如何解决的问题.

最有可能解决方案很简单,但我需要一些指导......

在我的project.spec.js文件中,这是给出问题的代码:

it("should not save when name is empty", function() {
    var eventSpy = sinon.spy();
    this.project.bind("error", eventSpy);
    this.project.save({"name": ""});
    expect(this.eventSpy.calledOnce).toBeTruthy();
    expect(this.eventSpy.calledWith(
      this.project, 
      "cannot have an empty name"
    )).toBeTruthy();
});

这是在浏览器中可以看到的特定错误:

Failing 1 spec

Project model should not save when name is empty.

    at jasmine.Queue.next_ (http://localhost:8888/__JASMINE_ROOT__/jasmine.js:2035:14)

除了sinon.js库之外,我还安装了jasmine-sinon.js库(两者都在vendor/assets/javascripts文件夹中,并包含在application.js文件中).

当我从GitHub(没有Sinon文件夹)下载sinon.js文件时,我遇到了这个问题.我从http://sinonjs.org/下载了库来解决问题
