使用Karma/Jasmine/JSPM单元测试角度服务

Question

我正在为使用Karma和Jasmine在Angular 1和JSPM中编写的应用程序编写单元测试。

这里是我的噶配置（JSPM部分）：

jspm: { 
    meta: { 
     'jspm_packages/github/angular/angular.js': { 
      format: 'global', 
      exports: 'angular' 
     }, 
     'jspm_packages/github/angular/angular-mocks.js': { 
      format: 'global', 
      deps: 'angular' 
     } 
    }, 
    loadFiles: [ 
     'test/**/*.js' 
    ], 
    serveFiles: [ 
     'app/**/*.js' 
    ] 
}, 

首先，我想测试自定义的角度服务：

// imports 

class Game { 

    constructor($rootScope, $http, $timeout, $translate, $location) { 

     // ... 

     this.$rootScope.game = this; 

    } 

} 

这里是我的测试文件：

import { module, inject } from 'angular-mocks'; 

describe('this is a test', function() { 

    beforeEach(module('module-name')); 

    var game; 

    beforeEach(inject(function(_game_) { 
     game = new _game_; 
    })); 

    it('should be defined', function() { 
     expect(game).toBeDefined(); 
    }); 
}); 

主要问题是我一直有这个错误。来自angular-mocks的inject函数似乎不起作用，因为我没有定义我的变量game，但它应该是。

    drain@D:/{path}/jspm_packages/system-polyfills.src.js:67:15 

所以，我不明白为什么它不起作用。任何线索？

也许太晚了现在，但尝试没有新的关键字：

beforeEach(inject(function(_game_) { 
    game = _game_; 
}));
