这个单元测试失败的原因是什么

代码：

$scope.nextStep = function(route) {
    session.save($scope.sessionViewModel);
    var input = {
        emailAddress : session.account.email,
        caller : 'USERNAME_EXIST'
    };
    webServiceDal.doesWebLoginExist(input).success(function(response) {
        console.log(response.WebLoginAppResponse.errorFlag);
        if ((response.WebLoginAppResponse.errorFlag) && ((response.WebLoginAppResponse.returnCode == 1006) || (response.WebLoginAppResponse.returnCode == 'MSG0307'))) {
        $scope.globalError = $scope.validationViewModel.email.existErrorMessage;
        }
        else
        $location.path(route);
    });
    };

测试：

describe('forgotPasswordCtrl', function() {
    beforeEach(module('forgotPasswordApp'));

    var scope, controller, q, $location, route, deferred, mockSessionService, validationProviderMock, webServDalMock;
    beforeEach(function(){
        var config = {
                urlPath : {
                    match : ""
                }
        };
        validationProviderMock = {
        };
        var response = {
        };
    mockSessionService = {
        account : {
            email : ""
        },
        clear : function(){
            return true;
            }
    };
    webServDalMock = {
        forgotPassword : function(){
            deferred = q.defer();
            deferred.resolve(response);
            return deferred.promise;
        },
        doesWebLoginExist : function(){
            deferred = q.defer();
            deferred.resolve(response);
            return deferred.promise;
        }
    };
    spyOn(webServDalMock, 'forgotPassword').and.callThrough();
    spyOn(webServDalMock, 'doesWebLoginExist').and.callThrough();
    spyOn(mockSessionService, 'clear').and.callThrough();
}); 
        beforeEach(inject(function($rootScope, $controller, _$location_, $q){
        scope = $rootScope.$new();
        $location = _$location_;
        q = $q;
        controller = $controller('forgotPasswordCtrl', { $scope: scope, webServiceDal : webServDalMock, session : mockSessionService, validationProvider : validationProviderMock });
        scope.$apply();
        }));

        it('should call clear method of session', function(){
            scope.cancel();
            expect(mockSessionService.clear).toHaveBeenCalled();
        });
        it('should return the correct url', function(){
            scope.cancel();
            config.urlPath.match("tfgm_customer");
            expect(window.location.assign).toEqual("/web/tfgm_customer");
        });
        it('asf', function(){
            scope.cancel();
            config.urlPath.match("tfgm_customerERROR");
            expect(window.location.assign).toEqual("/web/tfgm_admin");
        });
        it('should call webServiceDal', function(input){
            scope.finish();
            scope.$apply();
            expect(webServDalMock.forgotPassword).toHaveBeenCalled();
        });
        it('should call webServiceDal', function(){
            scope.nextStep(route);
            scope.$apply();
            expect(webServDalMock.doesWebLoginExist).toHaveBeenCalled();
        });
 });

每个之前：

beforeEach(inject(function($rootScope, $controller, _$location_, $q){
        scope = $rootScope.$new();
        $location = _$location_;
        q = $q;
        controller = $controller('forgotPasswordCtrl', { $scope: scope, webServiceDal : webServDalMock, session : mockSessionService, validationProvider : validationProviderMock });
        scope.$apply();
        }));

不能解决我的生活为什么这没有过去？我已经调用了正确的函数，并且正确地调用了expect。我对其他文件进行了相同的测试，唯一的区别是变量的命名等，它们都通过了。我是不是错过了一些简单的东西？
