使用Karma / Jasmine / JSPM对角度服务进行单元测试

Question

我正在使用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，我想测试一个定制的角度服务：

// 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();
    });
});

主要问题是我仍然遇到此错误。 来自angular-mocks的inject函数似乎不起作用，因为我没有定义变量game ，但应该定义它。

    _drain@D:/{path}/jspm_packages/system-polyfills.src.js:102:22
    drain@D:/{path}/jspm_packages/system-polyfills.src.js:67:15

因此，我不知道为什么它不起作用。 有什么线索吗？

Answer 1

也许到现在为止为时已晚，但是请在没有new关键字的情况下进行尝试：

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