用Karma/Jasmine/JSPM对angular服务进行单元测试

Unit-testing an angular service with Karma/Jasmine/JSPM

我正在为我用Angular 1和JSPM与Karma和Jasmine编写的应用程序编写单元测试。

这是我的Karma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，我想测试一个自定义的angular服务: 
// imports
class Game {
    constructor($rootScope, $http, $timeout, $translate, $location) {
        // ...
        this.$rootScope.game = this;
    }
}

这是我的测试文件:

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。从angular-mock的inject函数似乎不工作，因为，我有我的变量game没有定义，但它应该是。

    _drain@D:/{path}/jspm_packages/system-polyfills.src.js:102:22
    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。有线索吗?

现在可能太迟了，但是试试不使用新的关键字:

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