Angular（ng 测试）调试 - VS Code 未在断点处停止

Question

我目前遇到问题。我开始为我的 Angular 应用程序编写测试并想要调试它们。现在我已经用谷歌搜索了很多，我尝试了来自微软的食谱（https://github.com/Microsoft/vscode-recipes/tree/master/Angular-CLI），而我最接近使它工作的是这个BlogPost

http://blog.mlewandowski.com/Debugging-Karma-tests-with-VSCode.html

现在至少我可以将调试器附加到 VS-Code。然而，VS Code 仍然不会在断点处停止，而是测试继续运行。VS Code 中的断点也将保持未经验证的状态（见图）

这就是我到目前为止所拥有的（我只提供我更改过的部分，以免发布太多代码）。

知道我做错了什么吗？除此之外，调试工作正常。我可以调试我的 Node.js 应用程序，并且调试 ng 服务也可以正常工作。

启动.json

{
    "type": "chrome",
    "request": "attach",
    "name": "MyApp - Tests",
    "address": "localhost",
    "port": 9222,
    "pathMapping": {
        "/": "${workspaceRoot}",
        "/base/": "${workspaceRoot}"
    }
}

karma.conf.js

browsers: [
    'ChromeDebugging'
],

customLaunchers: {
    ChromeDebugging: {
        base: 'Chrome',
        flags: ['--remote-debugging-port=9222']
    }
}

您是否安装了“Chrome 调试器”扩展程序。

看看这个指南。 https://github.com/Microsoft/vscode-recipes/tree/master/Angular-CLI

更新：这是我的 launch.json 也许你可以尝试一下。

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "ng serve",
      "type": "chrome",
      "request": "launch",
      "url": "http://localhost:4200/#",
      "webRoot": "${workspaceFolder}"
    },
    {
      "name": "ng test",
      "type": "chrome",
      "request": "launch",
      "url": "http://localhost:9876/debug.html",
      "webRoot": "${workspaceFolder}"
    },
    {
      "name": "ng e2e",
      "type": "node",
      "request": "launch",
      "program": "${workspaceFolder}/node_modules/protractor/bin/protractor",
      "protocol": "inspector",
      "args": ["${workspaceFolder}/e2e/protractor.conf.js"]
    }
  ]
}
