"justMyCode": false is not respected at debug-test configurations

[Akay7]

Type: Bug

I pretty sure that I was able to step out of my code, but recently I found that I unable to debug code that is not in my project.

Seems that "justMyCode": false is not respected at debug-test configurations

  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python: Debug Tests",
      "type": "debugpy",
      "request": "launch",
      "program": "${file}",
      "purpose": ["debug-test"],
      "console": "integratedTerminal",
      "presentation": {
          "hidden": true, // keep original launch order in 'run and debug' tab
      },

        "DJANGO_MAILGUN_ENABLED": "False",
      },
      "justMyCode": false
    }
  ]

I also have found this recently.
Used to work just fine with a test debug configuration of:

        {
            "name": "Python: Debug Unit Tests",
            "type": "python",
            "request": "launch",
            "purpose": ["debug-test"],
            "console": "integratedTerminal",
            "justMyCode": false,
        }

But now, no matter what combination I do of launch.json and the justMyCode setting in the Python Debugger extension GUI settings I am not able to debug code within imported modules.

[eleanorjboyd]

What version of python are you using?

[Akay7]

I'm using
Python 3.12.8 (main, Dec 04 2024, 21:53:56) [GCC] on linux

[dalemyers]

I'm also seeing this. It used to work fine.

launch.json:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "bashdb",
            "request": "launch",
            "name": "Bash-Debug Current File",
            "cwd": "${workspaceFolder}",
            "program": "${file}",
            "pathBash": "/opt/homebrew/bin/bash",
            "args": []
        },
        {
            "name": "Python: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "justMyCode": false
        },
        {
            "name": "Python: Debug Tests",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "purpose": [
                "debug-test"
            ],
            "console": "integratedTerminal",
            "justMyCode": false
        }
    ]
}

settings.json (just Python settings):

{
    "python.defaultInterpreterPath": "${workspaceFolder}/../../.venv/bin/python3",
    "python.testing.pytestArgs": [
        "--rootdir=${workspaceFolder}",
        "tests"
    ],
    "python.testing.pytestPath": "${workspaceFolder}/../../.venv/bin/pytest",
    "python.testing.pytestEnabled": true,
    "python.testing.unittestEnabled": false,
}

I have no Python settings in my user settings.

Python version: 3.13.1
Pytest version: 7.4.4
VSCode version: 1.96.4
Python extension version: 2024.22.2
Python debugger extension version: 2024.14.0

All I'm doing is selecting the testing pane on the left, finding a test, then clicking the "debug" test button. Breakpoints are hit, but I just can't step in to code that is not mine.

@eleanorjboyd I'm internal to MS, so feel free to reach out for debugging steps. My alias is dalemyers.

does it make a difference setting "type" to "debugpy"? I tried this myself and it worked

[eleanorjboyd]

@dalemyers, thanks for the detailed description. For you config with the debug test, what is the purpose of setting this: "program": "${file}",?

I gave your config a try on my machine and it worked. What OS are you using and are you connected to a remote? Also if you set your logs to info, do you see this in your python logs Using configuration in launch.json. To do so first set your log level to trace via the Developer: set log level command in the command palette then check the output panel and select "python" from the dropdown.

[dalemyers]

or you config with the debug test, what is the purpose of setting this: "program": "${file}",?

I have no idea... It's copied from somewhere. Removing it didn't change anything.

What OS are you using

macOS 15.2

are you connected to a remote

No. Entirely local.

do you see this in your python logs Using configuration in launch.json

Yes.

[bzczb]

justMyCode=false in launch.json and debugpy.debugJustMyCode=false in settings.json are working again for me in unit tests, after the latest update!

Dupe of #24439 ?

[Akay7]

Now it started working again, without any changes on my side. So if anyone has the same problem, try updating.
