anchor.diff:    We tell Webpack to find and load our test files (the files ending in `.spec.ts`).
     Each spec file imports all &mdash; and only &mdash; the application source code that it tests.
     Webpack loads just _those_ specific application files and ignores the other files that we aren't testing.

  +  注意，我们_并没有_明确加载我们的应用代码。
  +  我们只告诉Webpack查找并加载我们的测试文件(文件名以`.spec.ts`结尾)。
  +  每个规约(spec)文件都导入了所有(也只有)它测试所需的应用源码。
  +  Webpack只加载_那些_特定的应用文件，而忽略所有其它我们不会测试到的。
