angularjs - 使用 Jasmine 测试 AngularJS 的 .then() 返回值

Question

这是我的 AngularJS:

self.fetch = {
 things: function() {
   return $http.get("/things/")
     .then(function(response) {
         return response.data;
   });
 }
};

这是我的测试:

it('fetch.things() should GET to /things/, success', function() {
    mockBackend.expectGET("/thingss/").respond({stuffs: 'stuffs'});

    var response = BaseService.fetch.things();

    mockBackend.flush();

    expect(response).toEqual({stuffs: 'stuffs'})
});

这是我得到的错误:

Expected Object({ $$state: Object({ status: 1, value: Object({ stuffs: 'stuffs' }) }) }) to equal Object({ stuffs: 'stuffs' }).
        at Object.<anonymous> (tests/test_base.js:28:26)

那个额外的 status: 1, 东西是什么？它来自哪里？

在测试中尝试以下操作；

it('fetch.things() should GET to /things/, success', function() {
   mockBackend.expectGET("/things/").respond({stuffs: 'stuffs'});
   var p = BaseService.fetch.things();

   mockBackend.flush();

   p.then(function(response){
      expect(response.data).toEqual({stuffs: 'stuffs'})
   });

   $rootScope.digest();

   return p;
});
