茉莉花spyOn不会转到.then函数与angularJS

Question

这是我的控制器

function test(){
    console.log('trace1'); // this gets print on console
    myService.useService('someStuff')
      .then(function(data){
          console.log('trace2'); // this doesn't get print
      })
      .catch(function(error){
          console.log('trace3'); // this doesn't get print    
      });
}

这是我的测试套件

describe('test controller promise', function () {

    beforeEach(inject(function(
        $controller,
        $q,
        _$rootScope_,
        $location,
        $anchorScroll,
        _myService_,
        $window
    ) {
        $rootScope = _$rootScope_;
        myService = _myService_;

        var testDeferred = $q.defer();
        testDeferred.reject('some_error_message');

        spyOn(myService, 'useService').and.callFake(function(){
            console.log('trace 5');  // this gets called
            return testDeferred.promise
        });

        myController = $controller('myController', {
            $rootScope: $rootScope,
            myService: myService,
            $location: $location,
            $anchorScroll: $anchorScroll,
            $window
        });

        $rootScope.$apply();
    }));

    it('test promise', function () {
        myController.test();

        // we see trace1 and trace5 gets called but not trace2 and trace3
});

我想无论是.then或.catch模拟服务被称为（理想情况下，我应该看到后调用trace3，因为我用来获取打印reject），但我们看到，它不会因为所谓的trace2和trace3没有得到打印的，但什么是好奇的是自从trace5被打印以来，Fake函数确实被调用

我试过了callFake，returnValue并且同时使用reject和resolve，它们都不会导致.then或.catch不会被调用。我想念什么？
