Angularjs 使用jasmine在Angular JS中测试$q的返回值

我的工厂如下：

var myFactory = function ($q) {
    factory = {};

    factory.newObject = function() {
        return $q.when({ id: 0 }});
    };
};

angular.module('myModule').factory('myFactory', myFactory);

如何使用jasmine测试newObject函数并确保返回的id为0？ 以下是我目前掌握的情况：

describe("My Factory Test", function () {

    var testMyFactory;

    beforeEach(module('myModule'));

    beforeEach(inject(function (myFactory) {
        testMyFactory = myFactory;
    }));

    it('New Entity', function ($q) {
        testMyFactory.newObject().then(function(myObj) {
            expect(myObj.id).toBe(0); // does not work
        });
    });
});

这起到了作用：

describe("My Factory Test", function () {

  var testMyFactory, rootScope;

  beforeEach(module('myModule'));

  beforeEach(inject(function (myFactory, $rootScope) {
    testMyFactory = myFactory;
    rootScope = $rootScope;
  }));

  it('New Entity', function () {
    var testObj;
    testMyFactory.newObject().then(function(myObj) {
        testObj = myObj;
    });

    rootScope.$apply();
    expect(testObj.id).toBe(0);
  });
});
