Question

我为Karma 0.13.22运行的Angular 2.0项目提供了一组有效的单元测试，连接到带有Socket.io 1.4.5的Chrome 48浏览器。我正在这个配置下进行测试，该工作正常：

app/
tests/app
karma-test-shim.js
karma.conf.js

然后，在不更改任何代码的情况下，我移动了一个文件夹：

source/app/
tests/app
karma-test-shim.js
karma.conf.js

...然后我使用新路径更新了karma-test-shim.js和karma.conf.js。

现在测试甚至都没有运行，我收到了这个错误：

Missing error handler on `socket`.
TypeError: (msg || "").replace is not a function
  at /home/spryno724/projects/portfolio/node_modules/karma/lib/reporter.js:45:23
  at onBrowserError (/home/spryno724/projects/portfolio/node_modules/karma/lib/reporters/base.js:58:60)
  ... more stack trace ...

11 03 2016 20:24:11.038:WARN [Chrome 48.0.2564 (Windows 10 0.0.0)]: Disconnected (1 times)

知道造成这种情况的原因是什么？唯一更改的是文件夹路径。

来自karma.conf.js 的示例：

files: [
  // Load Angular 2 dependencies and the SystemJS shim
  { pattern: 'node_modules/angular2/bundles/angular2-polyfills.js', included: true, watched: true },
  { pattern: 'node_modules/systemjs/dist/system.src.js', included: true, watched: true },
  { pattern: 'node_modules/rxjs/bundles/Rx.js', included: true, watched: true },
  { pattern: 'node_modules/angular2/bundles/angular2.dev.js', included: true, watched: true },
  { pattern: 'node_modules/angular2/bundles/testing.dev.js', included: true, watched: true },
  { pattern: 'karma-test-shim.js', included: true, watched: true },

  // The application and test files
  { pattern: 'source/app/**/*.js', included: false, watched: false },
  { pattern: 'test/unit/app/**/*.js', included: false, watched: false },

  // Support for debugging sessions
  { pattern: 'source/app/**/*.ts', included: false, watched: false },
  { pattern: 'test/unit/app/**/*.js.map', included: false, watched: false }
]

您可以尝试更改您的karma-test-shim.js。在System.config下，更改格式：＆＃39;注册＆＃39;格式化：＆＃39; cjs＆＃39;。

我复制了你的karma.conf.js + karma-test-shim.js并创建了一个简单的项目来模拟你遇到的问题（修复如上）。 https://github.com/phhoangbao/angular2-test

业力：移动文件夹 - ＆gt;套接字上缺少错误处理程序？
