Karma和jasmine中的依赖问题

我想用Karma和Jasmine来测试我的AngularJS应用程序 . 我已经安装了所有与业力有关的事情 . 在karma.conf.js文件中，我给出了gulped bower.js（它将包含所有bower组件）并吞下all.js（所有js文件）和testcase文件 . 但我得到一个依赖性问题，这是不允许我进一步的 . 如果我在不使用beforeEach的情况下编写简单的测试用例，它将获得perferctly执行 . 但我正在研究真正的项目，所以需要将控制器注入我的模块 . 但是当我使用beforeEach时（注入......，我得到了这个问题 . 我想知道哪里出了问题 .

所以这是我的karma.conf.js

files: [
            './tests/_bower.min.js',
            './bower_components/angular-mocks/angular-mocks.js',
            ' D:/testCase/project-pro/public_html/js/all.js',

            './tests/demotest.spec.js'
        ],

和我简单的测试用例

describe('settingsCtrl', function () {
        var $controller, settingsCtrl, scope;


        beforeEach(angular.mock.module('app'));

        // Inject the $controller service to create instances of the controller we want to test
        beforeEach(inject(function (_$controller_, _$rootScope_) {
            scope = _$rootScope_.$new();
            $controller = _$controller_;
        }));

       //  Verify our controller exists
      it('should be defined', function() {
        expect(settingsCtrl).toBeDefined();
      });

    });

这是我的问题
