使用 Jasmine 时出现未定义函数错误

Question

我认为通过编写这样的 Jasmine 模拟，我取得了不错的进展。但我无法修复此错误。

spyOn 方法实际上是如何工作的？实际上这种方法似乎应用广泛。 2.0 中有什么变化吗

describe('Test Controller', function() {

var $scope, $rootScope, $q, controller, mockService, queryDeferred;

//What is the expected response ?
var expectedResponse = [{ suffix: 'Mr.'}, { prefix: 'Miss'}];

beforeEach(function () {
  angular.module("Test", []);
});

beforeEach(module('Test'));

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


      mockService = {
        query: function() {
          queryDeferred = $q.defer();
          return queryDeferred.promise;
        }
      }


      spyOn(mockService, 'query').andCallThrough();

      // inject the mocked Service into the controller.
      controller = $controller('TestController', {
        '$scope': $scope,
        'ServiceApi': mockService
      });



}));

});

更新：

我将此工作代码作为答案发布。我解决了一些问题。

describe('Test Controller', function() {

    var $q,
        $rootScope,
        $scope,
        mockService,
        mockResponse = [{ suffix: 'Mr.'}, { prefix: 'Miss'}];



    beforeEach(module('myApp'));

    beforeEach(inject(function(_$q_,
                               _$rootScope_) {
        $q = _$q_;
        $rootScope = _$rootScope_;
    }));

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

        mockService = {
            query: function() {
                queryDeferred = $q.defer();
                return {$promise: queryDeferred.promise};
            }
        }

         spyOn(mockService, 'query').and.callThrough();

         $controller('TestCtrl', {
           '$scope': $scope,
           'testService': mockService
         });

    }));

    describe('Given a setup for the invocation of the mock query', function() {
            beforeEach(function() {
                queryDeferred.resolve(mockResponse);
                $rootScope.$apply();
            });

           it('When the call to the mock service is issued ', function() {

               resolvespy = jasmine.createSpy('resolve');
               rejectspy = jasmine.createSpy('reject');

               expect(mockService.query).toHaveBeenCalled();

               var q = $scope.getPromise();

               q.then(resolvespy,rejectspy);

               queryDeferred.resolve(mockResponse);
               $rootScope.$apply();


               expect(resolvespy).toHaveBeenCalledWith(mockResponse);
               expect(rejectspy).not.toHaveBeenCalled();

           });

           it('Then the mock service should have returned the correct response', function() {

              expect($scope.test).toBe(mockResponse);
          });

            it('Then the mock service should have returned the correct response', function() {

                expect($scope.testfunction).toBeDefined();
            });

            it("should do something else when something happens", function() {
                $scope.testfunction();
                expect($scope.value).toBe('value');
            });
      });

});

在 Jasmine 2.0 中，您应该替换：

andCallThrough();

与：

and.callThrough();

参见： Jasmine 2.0 documentation and Upgrading to 2.0
