javascript - AngularJS 单元测试 : Injected Services undefined

Question

由于注入(inject)器未正确注入(inject)，我在单元测试 angularJS 时遇到了困难。我注入(inject)的任何内容结果都是 undefined。

模块:

app.module.js

angular.module('myServices', []);

AngularTest.js

describe('AngularTest', function() {

    beforeEach(module('myServices'));

    var scope;

    beforeEach(inject(function(_$rootScope_) {
        // The injector unwraps the underscores (_) from around the parameter names when matching
        scope = _$rootScope_;

    }));

    describe('Testing Angular injection', function() {

      it('scope should be defined', function() {    
        expect(scope).toBeDefined(); // fails
      });

    });
});

我已经成功地在我的主模块中测试了 Controller ，但是，这个特定的模块正在测试我的理智。

有什么想法吗？

业力文件:

files: [
      'app/bower_components/angular/angular.js',
      'app/bower_components/angular-resource/angular-resource.js',
      'app/bower_components/angular-route/angular-route.js',
      'app/bower_components/angular-animate/angular-animate.js',
      'app/bower_components/angular-cookies/angular-cookies.js',
      'app/bower_components/angular-mocks/angular-mocks.js',
      'app/app.module.js',
      'app/components/**/controller/*.js',
      'app/components/**/model/*.js',
      'app/components/**/test/unit/*.js'
    ]

服务模块在app.module.js中定义，服务在app/components/services/model/myService.js(路径似乎不合逻辑，我试图抽象我的结构以尽可能概括这个问题)

Karma 似乎也没有提示:来自日志:

28 08 2015 03:38:47.095:WARN [karma]: No captured browser, open http://localhost:9876/

后面是失败的测试用例:

该死的 SAFARI!

解决方案:在 karma 配置文件中将浏览器更改为 Chrome，调试日志会输出更详细的错误信息!

原来我没有在我的业力 文件 中包含所需的模块依赖项。
