茉莉花控制器測試，預計間諜被稱為

Question

我有一個在AngularJS控制器中定義的方法，在初始化時調用。 我想用Jasmine測試它（ "jasmine-core": "^2.3.4", "karma": "^0.12.37" ）。 我在互聯網和StackOverflow問題上遵循一些教程，但我找不到正確的答案。 請看一下這段代碼：

Controller usersAddUserController ：

(function () {
    'use strict';

    angular.module('app.users.addUser')
        .controller('usersAddUserController', ['$scope', 'usersAddUserService', function ($scope, usersAddUserService) {

            usersAddUserService.getCountryPhoneCodes().then(function (phoneCodes) {
                $scope.phoneCodes = phoneCodes;
            });

        }]);
}());

茉莉花測試：

(function () {

    'use strict';

    describe('usersAddUserControllerUnitTest', function () {
        var scope, deferred, objectUnderTest, mockedAddUserService;

        beforeEach(module('app'));

        beforeEach(inject(function ($rootScope, $q, $controller) {
            scope = $rootScope.$new();

            function emptyPromise() {
                deferred = $q.defer();
                return deferred.promise;
            }

            mockedAddUserService = {
                getCountryPhoneCodes: emptyPromise
            };

            objectUnderTest = $controller('usersAddUserController', {
                $scope: scope,
                usersAddUserService: mockedAddUserService
            });
        }));

        it('should call getCountryPhoneCodes method on init', function () {
            //when            
            spyOn(mockedAddUserService, 'getCountryPhoneCodes').and.callThrough();

            deferred.resolve();

            scope.$root.$digest();

            //then
            expect(mockedAddUserService.getCountryPhoneCodes).toHaveBeenCalled();
        });

    });
}());

運行測試后，錯誤消息是：

PhantomJS 1.9.8（Windows 7 0.0.0）usersAddUserControllerUnitTest應該在init FAILED上調用getCountryPhoneCodes方法

  Expected spy getCountryPhoneCodes to have been called. 

我顯然遺漏了一些東西，但我無法弄清楚它是什么。 任何幫助將不勝感激。

在將模型傳遞到實例化控制器后，您正在監視模擬。

嘗試這個：

describe('usersAddUserControllerUnitTest', function () {
    var scope, deferred, objectUnderTest, mockedAddUserService, $controller;

    beforeEach(module('app'));

    beforeEach(inject(function ($rootScope, $q, _$controller_) {
        scope = $rootScope.$new();

        function emptyPromise() {
            deferred = $q.defer();
            return deferred.promise;
        }

        mockedAddUserService = {
            getCountryPhoneCodes: emptyPromise
        };

        $controller = _$controller_;
    }));

    function makeController() {    
        objectUnderTest = $controller('usersAddUserController', {
            $scope: scope,
            usersAddUserService: mockedAddUserService
        });
    }

    it('should call getCountryPhoneCodes method on init', function () {
        //when

        spyOn(mockedAddUserService, 'getCountryPhoneCodes').and.callThrough();
        makeController();

        deferred.resolve();

        scope.$root.$digest();

        //then
        expect(mockedAddUserService.getCountryPhoneCodes).toHaveBeenCalled();
    });

});

編輯感謝@juunas注意到我的解決方案中的錯誤

您可以像這樣提供模擬：

mockedAddUserService = {
    getCountryPhoneCodes: emptyPromise
};


beforeEach(function () {
    module(function ($provide) {
        $provide.value('usersAddUserService', mockedAddUserService);
    });
});

編輯：

代碼應該看起來（因為我無法測試它）像這樣：

(function () {
    'use strict';

    describe('usersAddUserControllerUnitTest', function () {        
        beforeEach(module('app'));

        var emptyPromise = function() {
            var deferred = $q.defer();
            return deferred.promise;
        }

        var mockedAddUserService = {
            getCountryPhoneCodes: emptyPromise
        };

        beforeEach(function () {
            module(function ($provide) {
                $provide.value('usersAddUserService', mockedAddUserService);
            });
        });

        var scope;
        beforeEach(inject(function ($rootScope, $q, $controller) {
            scope = $rootScope.$new();
            $controller('usersAddUserController', {
                $scope: scope
            });
        }));

        it('should call getCountryPhoneCodes method on init', function () {
            spyOn(mockedAddUserService, 'getCountryPhoneCodes').and.callThrough();

            scope.$root.$digest();

            expect(mockedAddUserService.getCountryPhoneCodes).toHaveBeenCalled();
        });

    });
}());
