angularjs – 如何改变茉莉花间谍的回报值？

beforeEach(inject(function ($injector) {
    $rootScope = $injector.get('$rootScope');
    $state = $injector.get('$state');
    $controller = $injector.get('$controller');

    socket = new sockMock($rootScope);

    //this is the line of interest
    authService = jasmine.createSpyObj('authService',['login','logout','currentUser']);
}));

我想要更改authService的各种方法返回的内容.

以下是实际测试的设置：

function createController() {
    return $controller('UserMatchingController',{'$scope': $rootScope,'socket':socket,'authService': authService });
}

describe('on initialization',function(){
    it('socket should emit a match',function() {
        createController();

        expect(socket.emits['match'].length).toBe(1);
    });

    it('should transition to users.matched upon receiving matched',function(){

        //this line fails with "TypeError: undefined is not a function"
        authService.currentUser.andReturn('bob');

        createController();

        $state.expectTransitionTo('users.matched');
        socket.receive('matchedblah',{name: 'name'});

        expect(authService.currentUser).toHaveBeenCalled()
    })
})

控制器的设置方式如下：

lunchrControllers.controller('UserMatchingController',['$state','socket','authService',function ($state,socket,authService) {
        socket.emit('match',{user: authService.currentUser()});

        socket.on('matched' + authService.currentUser(),function (data) {
            $state.go('users.matched',{name: data.name})
        });
    }]);

从本质上讲,我希望能够更改间谍方法的返回值.但是,我不知道如果我正在使用jasmine.createSpyObj正确地解决了这个问题.
