Javascript 角度ui/引导：测试使用对话框的控制器

我有一个使用angular ui/引导程序对话框的控制器：

   function ClientFeatureController($dialog, $scope, ClientFeature, Country, FeatureService) {

        //Get list of client features for selected client (that is set in ClientController)
        $scope.clientFeatures = ClientFeature.query({clientId: $scope.selected.client.id}, function () {
            console.log('getting clientfeatures for clientid: ' + $scope.selected.client.id);
            console.log($scope.clientFeatures);
        });

        //Selected ClientFeature
        $scope.selectedClientFeature = {};

        /**
         * Edit selected clientFeature.
         * @param clientFeature
         */
        $scope.editClientFeature = function (clientFeature) {
            //set selectedClientFeature for data binding
            $scope.selectedClientFeature = clientFeature;

            var dialogOpts = {
                templateUrl: 'partials/clients/dialogs/clientfeature-edit.html',
                controller: 'EditClientFeatureController',
                resolve: {selectedClientFeature: function () {
                    return clientFeature;
                } }
            };
            //open dialog box
            $dialog.dialog(dialogOpts).open().then(function (result) {
                if (result) {
                    $scope.selectedClientFeature = result;
                    $scope.selectedClientFeature.$save({clientId: $scope.selectedClientFeature.client.id}, function (data, headers) {
                        console.log('saved.');
                    }, null);
                }
            });
        };
    });

我几乎完全不熟悉测试，我想也许我需要测试两件事：

调用$scope.editClientFeature（）时打开一个对话框

对话框关闭并返回“结果”后，成功调用$save

我的测试现在看起来非常糟糕：

describe('ClientFeatureController', function () {
    var scope, $dialog, provider;

    beforeEach(function () {
            inject(function ($controller, $httpBackend, $rootScope, _$dialog_) {
            scope = $rootScope;
            $dialog = _$dialog_;

            //mock client
            scope.selected = {};
            scope.selected.client = {
                id: 23805
            };

            $httpBackend.whenGET('http://localhost:3001/client/' + scope.selected.client.id + '/clientfeatures').respond(mockClientFeatures);
            $controller('ClientFeatureController', {$scope: scope});
            $httpBackend.flush();
        });
    });


    it('should inject dialog service from angular-ui-bootstrap module', function () {
        expect($dialog).toBeDefined();
        console.log($dialog); //{}
    });

    var dialog;

    var createDialog = function (opts) {
        dialog = $dialog.dialog(opts);
    };

    describe('when editing a clientfeature', function () {
        createDialog({});
        console.log(dialog); //undefined
//        var res;
//        var d;
//        beforeEach(function () {
//            var dialogOpts = {
//                template: '<div>dummy template</div>'
//            };
//            console.log(dialog);
//            d = $dialog.dialog(dialogOpts);
//            d.open();
//        });
//
//        it('should open a dialog when editing a client feature', function () {
//            expect(d.isOpen()).toBe(true);
//        });
    });

});

$dialog.messageBox = function (title, msg, btns) {
    return {
        open: function () {
            return {
                 then: function (callback) {
                      callback('ok'); // 'ok' will be set to param result
                 }
             }
        }
    }
 };

如果有人已经为一个类似的用例编写了一个测试，并且可以为我提供一个例子，那就太好了，因为我已经迷路了

谢谢，

就我个人而言，我试图嘲弄所有的服务。如果ui引导项目没有提供$dialog模拟，那么您应该在那里打开一个bug通知单，并要求他们提供一个。然而，创建一个也很容易

---

模拟服务应该有假的方法，这些方法除了返回承诺之外什么都不做。它还应该为您提供一个刷新所有异步方法的方法，以便更容易进行同步测试。

我也更喜欢一个合适的模拟。当它不可用时，我会修补该服务

要测试这一点：

$dialog.messageBox(title, msg, btns)
   .open()
   .then(function (result) {
       if (result == 'ok') {
            // block executed if user click OK
       }
});

您可以按如下方式修补$dialog：

describe('ClientFeatureController', function () {
    var scope, $dialog, provider;

    beforeEach(function () {
            inject(function ($controller, $httpBackend, $rootScope, _$dialog_) {
            scope = $rootScope;
            $dialog = _$dialog_;

            //mock client
            scope.selected = {};
            scope.selected.client = {
                id: 23805
            };

            $httpBackend.whenGET('http://localhost:3001/client/' + scope.selected.client.id + '/clientfeatures').respond(mockClientFeatures);
            $controller('ClientFeatureController', {$scope: scope});
            $httpBackend.flush();
        });
    });


    it('should inject dialog service from angular-ui-bootstrap module', function () {
        expect($dialog).toBeDefined();
        console.log($dialog); //{}
    });

    var dialog;

    var createDialog = function (opts) {
        dialog = $dialog.dialog(opts);
    };

    describe('when editing a clientfeature', function () {
        createDialog({});
        console.log(dialog); //undefined
//        var res;
//        var d;
//        beforeEach(function () {
//            var dialogOpts = {
//                template: '<div>dummy template</div>'
//            };
//            console.log(dialog);
//            d = $dialog.dialog(dialogOpts);
//            d.open();
//        });
//
//        it('should open a dialog when editing a client feature', function () {
//            expect(d.isOpen()).toBe(true);
//        });
    });

});

$dialog.messageBox = function (title, msg, btns) {
    return {
        open: function () {
            return {
                 then: function (callback) {
                      callback('ok'); // 'ok' will be set to param result
                 }
             }
        }
    }
 };

我一直在努力解决同样的问题，直到现在，在浏览github repo之后，我找到了对话测试，并以此作为起点：

var $dialog,$scope,$httpBackend;
  beforeEach(module('ui.bootstrap.dialog'));
  beforeEach(function(){
    inject(function (_$dialog_, _$httpBackend_, $controller){
      $dialog = _$dialog_;
      $httpBackend = _$httpBackend_;
      $httpBackend.expectGET('/appServer/list')
        .respond([{
            id:1,
            name:'test1'
          },
          {
            id:2,
            name:'test2'
          },
          {
            id:3,
            name:'test3'
          }]);


      //setup controller scope
      scope = {};
      ServerCtrl = $controller('ServerCtrl', {
        $scope: scope,
        $dialog:$dialog
      });
    });
  });

我发现写我自己的对话模拟是最清楚的。下面是一个模拟对话框以模拟选择“是”的示例

测试中的代码 测验

我从你的帖子中意识到，我忘了在beforeach中包含“ui.bootstrap”模块。非常感谢。

    describe('when deleting a house', function () {

        var fakeDialog = {
            open: function()
            {
                return {
                    then: function(callback) {
                        callback("yes");
                    }
                };
            }
        };

        beforeEach(inject(function($dialog) {
            spyOn($dialog, 'messageBox').andReturn(fakeDialog);
        }));

        it('should call the remove method on the houseRepository', function () {
            scope.remove({id: 99});
            expect(houseRepository.remove).toHaveBeenCalledWith(99);
        });

        // etc
    });
