AngularJS 1.2.2中$ http和$ httpBackend的惯用组成

我有一个AngularJS / Jasmine单元测试，可以与AngularJS 1.0.7正常工作，但在Angular 1.2.2中不起作用：

servicesSpec.js

describe('services', function() {
    beforeEach(module('workPadApp'));

    describe('taskGateway', function() {
        var sut;
        beforeEach(inject(function(taskGateway) {
            sut = taskGateway;
        }));

        describe('saving a task', function() {
            it('GETs correctly', inject(function($httpBackend) {
                $httpBackend.expectGET('/').respond({ foo : 'bar' });
                sut.createTask({ taskRef : 'baz' });
                $httpBackend.flush();
            }))
        })
    })
})

app.js

var workPadApp = angular.module('workPadApp', ['workPadApp.services']);

services.js

angular.module('workPadApp.services', []).

  factory('taskGateway', function($http, $q) {
    return {
      createTask : function(task) {
        $http.get('/')
          .success(function(response) {
            console.log('success');
          })
          .error(function(response) {
            console.log('error');
          });
      }
    }
  });

预期结果

当我使用AngularJS 1.0.7与Karma一起运行时，一切都很好：

日志：“成功”

Chrome 33.0.1750（Windows 7）：执行1之1成功（0.179秒/0.03秒）

实际结果

但是，当我用AngularJS 1.2.2运行它时，得到以下输出：

Chrome 33.0.1750（Windows 7）服务taskGateway保存任务正确获取失败

   Error: No pending request to flush !

我看了$ httpBackend的文档，那里的示例使用了一种更加势在必行的使用$injector服务的设置样式。

这让我感到惊讶，因为在1.0.7版中使用的声明式样式更加简洁。这真的是前进的唯一正确方法，还是我错过了一些东西？
