我正在为启动a $modal并使用返回的诺言执行一些逻辑的控制器编写单元测试。我可以测试触发$
modal的父控制器，但是我一生无法弄清楚如何模拟成功的诺言。

我尝试了多种方法，包括使用$q和$scope.$apply()强制履行承诺。但是，我得到的最接近的结果是与本 SO帖子中的最后一个答案相似的东西。

我已经在“旧的” $dialog模式中看到了几次这样的问题。在“新” $dialog模式下，我找不到太多的方法。

一些指针将不胜感激。

为了说明问题，我使用了UI Bootstrap文档中提供的示例，并进行了一些小的编辑。

控制器（主和模态）

'use strict';

angular.module('angularUiModalApp')
    .controller('MainCtrl', function($scope, $modal, $log) {
        $scope.items = ['item1', 'item2', 'item3'];

        $scope.open = function() {

            $scope.modalInstance = $modal.open({
                templateUrl: 'myModalContent.html',
                controller: 'ModalInstanceCtrl',
                resolve: {
                    items: function() {
                        return $scope.items;
                    }
                }
            });

            $scope.modalInstance.result.then(function(selectedItem) {
                $scope.selected = selectedItem;
            }, function() {
                $log.info('Modal dismissed at: ' + new Date());
            });
        };
    })
    .controller('ModalInstanceCtrl', function($scope, $modalInstance, items) {
        $scope.items = items;
        $scope.selected = {
            item: $scope.items[0]
        };

        $scope.ok = function() {
            $modalInstance.close($scope.selected.item);
        };

        $scope.cancel = function() {
            $modalInstance.dismiss('cancel');
        };
    });

视图（main.html）

<div ng-controller="MainCtrl">
    <script type="text/ng-template" id="myModalContent.html">
        <div class="modal-header">
            <h3>I is a modal!</h3>
        </div>
        <div class="modal-body">
            <ul>
                <li ng-repeat="item in items">
                    <a ng-click="selected.item = item">{{ item }}</a>
                </li>
            </ul>
            Selected: <b>{{ selected.item }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>

    <button class="btn btn-default" ng-click="open()">Open me!</button>
    <div ng-show="selected">Selection from a modal: {{ selected }}</div>
</div>

'use strict';

describe('Controller: MainCtrl', function() {

    // load the controller's module
    beforeEach(module('angularUiModalApp'));

    var MainCtrl,
        scope;

    var fakeModal = {
        open: function() {
            return {
                result: {
                    then: function(callback) {
                        callback("item1");
                    }
                }
            };
        }
    };

    beforeEach(inject(function($modal) {
        spyOn($modal, 'open').andReturn(fakeModal);
    }));


    // Initialize the controller and a mock scope
    beforeEach(inject(function($controller, $rootScope, _$modal_) {
        scope = $rootScope.$new();
        MainCtrl = $controller('MainCtrl', {
            $scope: scope,
            $modal: _$modal_
        });
    }));

    it('should show success when modal login returns success response', function() {
        expect(scope.items).toEqual(['item1', 'item2', 'item3']);

        // Mock out the modal closing, resolving with a selected item, say 1
        scope.open(); // Open the modal
        scope.modalInstance.close('item1');
        expect(scope.selected).toEqual('item1'); 
        // No dice (scope.selected) is not defined according to Jasmine.
    });
});
