使用Karma/Jasmine/JSPM單元測試角度服務

Question

我正在爲使用Karma和Jasmine在Angular 1和JSPM中編寫的應用程序編寫單元測試。

這裏是我的噶配置（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，我想測試自定義的角度服務：

// imports 

class Game { 

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

     // ... 

     this.$rootScope.game = this; 

    } 

} 

這裏是我的測試文件：

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(); 
    }); 
}); 

主要問題是我一直有這個錯誤。來自angular-mocks的inject函數似乎不起作用，因爲我沒有定義我的變量game，但它應該是。

    drain@D:/{path}/jspm_packages/system-polyfills.src.js:67:15 
    Expected undefined to be defined.

    runContinuation1@D:/{path}/jspm_packages/system-polyfills.src.js:1147:18 
    when@D:/{path}/jspm_packages/system-polyfills.src.js:935:20

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

所以，我不明白爲什麼它不起作用。任何線索？

Answer 1

也許太晚了現在，但嘗試沒有新的關鍵字：

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