Jasmine和angularjs,不能存根$httpBackend用于服务

前端之家收集整理的这篇文章主要介绍了Jasmine和angularjs,不能存根$httpBackend用于服务前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
查询$httpBackend后我似乎无法返回预期的结果,我不知道测试有什么问题.你能看看这个失败的最小例子吗?

谢谢!

你几乎就在那里,但你的测试中仍有2个问题:

>在$httpBackend被刷新之前验证了期望.它是$httpBackend.flush();模拟传入的响应
>在您的期望中,您正在比较对象实例(而不是它们的值),但AngularJS $资源将创建一个新数组,如https://stackoverflow.com/a/11966512/1418796中所述.您需要比较对象的值而不是引用.这样做的一种方法是:expect(angular.equals(briefs,fakeGetResponse)).toBeTruthy();

最后这里有一个测试传递的jsFiddle:http://jsfiddle.net/VFqFU/
