那是因为你的 mock 没有返回 location 对象以便能够链接.使用 Jasmine 2.0，您可以将模拟更改为:

That is because your mock does not return location object to be able to chain through. Using Jasmine 2.0 you can change your mock to:

var $locationMock = { path: function () { return $locationMock; }, 
                      search: function () { return $locationMock; } };

和

spyOn($locationMock, "path").and.callThrough();
spyOn($locationMock, "search").and.callThrough(); //if you are chaining from search

或添加:

spyOn($locationMock, "path").and.returnValue($locationMock);
spyOn($locationMock, "search").and.returnValue($locationMock); //if you are chaining from search

或者只是创建一个间谍对象(更少的代码):

Or just create a spy object (less code):

var $locationMock = jasmine.createSpyObj('locationMock', ['path', 'search']);

和

$locationMock.path.and.returnValue($locationMock);
$locationMock.search.and.returnValue($locationMock); //if you are chaining from search
