JSPM 和测试台以及无法解释的 "testing.js" 输出

Question

几天来我们一直在纠结，似乎无法真正解决实际问题。我们想创建一个测试平台，以增加我们的代码覆盖率，但事实证明这并不像预期的那么容易。

包含正确的区域文件后，我们通过查看来自 angular 的快速入门发现我们需要调用 TestBed.initTestEnvironment。其中需要参数，我们导入：

import * as browserTesting from '@angular/platform-browser-dynamic/testing';


TestBed.initTestEnvironment(
   browserTesting.BrowserDynamicTestingModule,
    browserTesting.platformBrowserDynamicTesting()
);

但是，一旦我们尝试运行通过 Karma（使用茉莉花），我们运行进入 404:

查看 "jspm_packages/npm/@angular/compiler@2.3.0/testing.js"，我们很快发现它保存了错误的信息：

module.exports = require('./bundles/compiler-testing.umd.js/index');

而不是预期的：

module.exports = require('./bundles/compiler-testing.umd');

如果我手动更正它，一切都会完美无缺。所以我的问题： 我们如何防止 JSPM 或任何人生成错误的 testing.js 文件？

我们的想法是，出于某种原因，jspm 认为 compiler-testing.umd.js 文件是一个文件夹，因此将 /index 附加到它

*我们通过 config.js 包含了 angular 文件：*

System.config({
  defaultJSExtensions: true,
  transpiler: "typescript",
  paths: {
    "github:*": "jspm_packages/github/*",
    "npm:*": "jspm_packages/npm/*"
  },

  map: {
    "@angular/common": "npm:@angular/common@2.3.0",
    "@angular/compiler": "npm:@angular/compiler@2.3.0",
    "@angular/core": "npm:@angular/core@2.3.0",

经过漫长而广泛的搜索和数小时的比较，我实际上找到了问题和解决所有这些问题的方法：

问题：angular2 示例都使用 npm_modules，因此他们调整了 systemjs 文件以使用 npm 文件夹，但是，我们选择使用 JSPM，因为这使我们的 backend/infrastructure 和我们的前端。让我们无需更改配置即可 add/remove/upgrade 包。因为 angular2 模块实际上是 2 个模块合二为一，它导致 JSPM 对此产生了一些有趣的事情，因此最终总是试图加载错误的文件：例如"core-testing.umd.js/index" 而不仅仅是 "core-testing.umd".
解决方案：终于我找到了金子：更新到 jspm 0.17（在撰写本文时仍处于测试阶段）

新的 JSPM 也能正确检测到测试模块，现在加载已正确完成！
