茉莉花测试与角度 ng 模拟不与控制器和承诺一起工作

Question

我一直在玩下面的代码，但我找不到问题，测试失败，出现以下消息："预期未定义而不是未定义。

我有一个服务，它向我的控制者返回承诺。在控制器中，我在解决承诺后立即使用 $q.all 做一些事情。

我试图遵循这个例子，但我看到的最大区别是，在示例中，它在控制器的根目录中有调用，我在方法"$scope"内有服务调用。客户测试"，所以我在申请($scope.$apply((("$scope。CustomerTest('Mr'(;"：

这是我的测试代码：

var $scope;
var $q;
var deferred;
var $httpBackend;
//Inject the module "before each test"
beforeEach(angular.mock.module('marketingApp'));
beforeEach(inject(function ($controller,_$httpBackend_,  _$rootScope_, _$q_, marketingService) {
    $q = _$q_;
    $scope = _$rootScope_.$new();
    $httpBackend = _$httpBackend_;
    // We use the $q service to create a mock instance of defer
    deferred = _$q_.defer();
    // Use a Jasmine Spy to return the deferred promise
    spyOn(marketingService, 'getTitleSuggested').and.returnValue(deferred.promise);
    // Init the controller, passing our spy service instance
    $controller('customerController', {
        $scope: $scope,
        marketingService: marketingService
    });
}));
it('should resolve promise', function () {
    // Setup the data we wish to return for the .then function in the controller
    var titles = [{ "Id": 1, "Name": "Mr" }];
    deferred.resolve(titles);
    $httpBackend.when('GET', '/MarketingCustomers/GetTitleSuggested')
        .respond(200, titles);
    //I call to the controller method here.
    $scope.CustomerTest('Mr');
    $scope.$apply();
    // Since we called apply, not we can perform our assertions
    //expect($scope.TitlesTest).not.toBe(undefined);
    expect($scope.SelectedCustomerTitle).toEqual('Mr');
    //expect($scope.error).toBe(undefined);
});

注释控制器的第一个测试(it(.js其他两个测试工作。请帮忙吗？

解决了我在这里的问题，如果有人有类似的问题，希望它能有所帮助。

这是测试：

describe('CustomerController.js', function() {
var results = [{
 "Id": 1,
 "Name": "Mr"
}];
var $controller;
var $q;
var $rootScope;
var $scope;
var marketingService;
beforeEach(angular.mock.module('marketingApp'));
beforeEach(inject(function(_$rootScope_, $controller, _$q_, 
_marketingService_) {
$scope = _$rootScope_.$new();
$q = _$q_;
$rootScope = _$rootScope_;
marketingService = _marketingService_;
$controller('customerController', {
  $scope: $scope,
  $rootScope: $rootScope
});
spyOn(marketingService, 'getTitleSuggested').and.callFake(function() {
  var deferred = $q.defer();
  deferred.resolve(results);
  return deferred.promise;
});
}));
it('It should call the service" ', function() {
$scope.CustomerTest('Mr');
expect(marketingService.getTitleSuggested).toHaveBeenCalledWith('Mr');
});

it('It should populate the "$scope.TitlesTest" ', function() {
$scope.CustomerTest('Mr');
$rootScope.$apply();
expect($scope.hello).toEqual('Hello Mr Marcos');
expect($scope.Titles[0].Name).toBe('Mr');
expect($scope.Titles).toBe(results);
});

}(;
