Question

我从AngularJs开始，当我尝试对具有服务作为依赖关系的控制器进行单元测试时，我遇到了问题。应用程序按预期工作，但不是单元测试。我在Jasmine测试中遇到以下错误：

Error: [$injector:modulerr] Failed to instantiate module ghhweb.register due to: Error: [$injector:unpr] Unknown provider: $stateProvider

我的模块代码：

var registerModule = angular.module('ghhweb.register',[]);

registerModule.config(function($stateProvider, $locationProvider){
    var registerState = {
        name: 'register',
        url: '/register',  
        controller: 'RegisterController',
        templateUrl: 'modules/register/views/register.html'
    };

    $stateProvider.state(registerState);
});

我的控制器代码：

var registerController = angular.module('ghhweb.register.controller',[]);

registerController.controller('RegisterController', ['$scope', 
    'userRestService', function($scope, userRestService){
    $scope.callCheckExistingMail = function(){
        $scope.userEmail = userRestService.checkExistingMail($scope.userEmail);
    };
}]);

我的规范代码：

describe('controller register module unit tests', function(){
    describe('check user service implementation', function(){

        beforeEach(module('ghhweb.register'));

        it('should call checkExistinMail in userRestService', inject(function(
                $rootScope, $controller){
            // make a userRestService
            var userRestService = {
                checkExistingMail: function() {}
            };

            spyOn(userRestService, "checkExistingMail");

            controller('RegisterController', {$scope: scope, 
                userRestService: userRestService });

            expect(userRestService.checkExistingMail).toHaveBeenCalled();
        }));

    });

});

我已经尝试了很多教程并检查了几个这样的帖子：

我想我在某个地方遇到配置问题，但我无法解决。

有没有人有想法？

我怀疑我以前的测试代码不适用于我现有的库版本。我正在使用：

"devDependencies": {
"bower": "^1.8.0",
"http-server": "^0.9.0",
"jasmine-core": "^2.4.1",
"karma": "^1.3.0",
"karma-chrome-launcher": "^2.0.0",
"karma-firefox-launcher": "^1.0.0",
"karma-jasmine": "^1.0.2",
"phantomjs": "^2.1.7",
"protractor": "^4.0.9"

经过进一步调查后，我按如下方式重写了测试代码：

    describe('controller register module unit tests implementation', function(){

    var $controller;
    var $scope;
    var userRestService;

    beforeEach(module('ghhweb.register.controller', function($provide){
        userRestService = jasmine.createSpyObj('userRestService'
            , ['checkExistingMail']);

        userRestService.checkExistingMail.and.returnValue(0);

        $provide.value('userRestService', userRestService);
    }));


    beforeEach(inject(function(_$controller_, $rootScope,_userRestService_){
        $scope = $rootScope.$new();
        userRestService = _userRestService_;
        $controller = _$controller_('RegisterController', {
            $scope: $scope,
            userRestService: userRestService
        });
        $scope.callCheckExistingMail();
    }));

    it('should call userRestService', function(){
        expect(userRestService.checkExistingMail).toHaveBeenCalled();
    });
});

现在测试运行正确！

无法对服务模拟的角度控制器进行单元测试
