How to debug tests with VS Code into a docker container

[a-kouyate]

I try to figure out how to debug tests into a docker container with VS Code.

I configured my launch.json as follows

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Attach to Docker",
      "type": "node",
      "request": "attach",
      "address": "localhost",
      "port": 9229,
      "localRoot": "${workspaceFolder}",
      "remoteRoot": "/srv/app",
      "restart": true,
      "sourceMaps": true,
      "skipFiles": ["<node_internals>/**"],
      "autoAttachChildProcesses": true,
      "trace": true // Optional: Enables detailed logging for debugging
    },
    {
      "name": "Attach to Docker Tests",
      "type": "node",
      "request": "attach",
      "address": "localhost",
      "port": 9230,
      "localRoot": "${workspaceFolder}",
      "remoteRoot": "/srv/app",
      "restart": true,
      "sourceMaps": true,
      "skipFiles": ["<node_internals>/**"],
      "autoAttachChildProcesses": true,
      "trace": true // Optional: Enables detailed logging for debugging
    }
  ]
}

I added this script into my package.json dev:debug": "node ace --inspect=0.0.0.0:9229 serve --hmr and I run my container as follows:
command: npm run dev:debug.

It's working well I debug API calls but nothing happen when trying to debug a running test.
