Debugging tests is not stopping on breakpoint

[pcolmer]

Type: Bug

Behaviour

Expected vs. Actual

Expected: setting a breakpoint on a test and then debugging the test should trigger the breakpoint to enable step-by-step execution of the test.

Actual: the test just runs through. The debugger panel appears at the top of the window but the debugger never stops execution of the code.

Steps to reproduce:

1. Right-click on the green run button in the test file's gutter.
2. Click "Add breakpoint". Green run button turns red.
3. Right-click and choose "Debug Test".

Diagnostic data

• Python version (& distribution if applicable, e.g. Anaconda): 3.10.4
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): PipEnv
• Value of the python.languageServer setting: Pylance

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

[int19h]

Does it break if you manually call breakpoint() in your test?

No, it doesn't - not in VS Code, at least. If I run pytest manually at the command line, it does drop into pdb.

[int19h]

This implies that the debugger doesn't get attached at all. By chance, are you using pytest-xdist or some similar facility that parallelizes test runs across multiple processes?

No - just plain pytest. Here is the settings file:

{
    "python.testing.pytestArgs": [
        "tests"
    ],
    "python.testing.unittestEnabled": false,
    "python.testing.pytestEnabled": true
}

Hi, guys. I hit the same issue. My breaking point is not working for the main function. I am in my codespace with
Pylance v2023.1.40
Python v2022.20.2
Version: 1.74.3 (Universal)
Commit: 97dec172d3256f8ca4bfb2143f3f76b503ca0534

Can you try enabling logging via "logToFile": true in your launch.json, and then sharing the logs after it fails to hit the breakpoints? It'll be a bunch of files named debugpy*.log on the remote machine under ~/.vscode-remote/extensions/ms-python*.

[pcolmer]

@int19h I don't have that directory. This is what I see in my home directory with those sort of filenames:

[pcolmer]

I'm not finding anything called debugpy*.log in any of those .vscode directories, I'm afraid.

[int19h]

It should be under .vscode-server-insiders/extensions/ms-python* in this case, I think. In general, it's the parent directory of the path that you see in the terminal when you start debugging that has "pythonFiles" in it.

Can you check that "logToFile" setting is in the correct debug configuration? It should also have "purpose": ["debug-test"] in it for the test runner to apply it.

Alternatively, just set the environment variable DEBUGPY_LOG_DIR to the path where you want the logs to go. It should also be set on remote, though, such that it is in scope for the debugged process; I think the easiest would be to set it from the CLI before running code in WSL. If your debug config is "request": "launch", you should be able to use "env" in the config as well.

[pcolmer]

Just as a sanity check, here is my launch.json file:

{
    // 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": [
        {
            "name": "Python: Flask",
            "type": "python",
            "request": "launch",
            "module": "flask",
            "env": {
                "FLASK_APP": "app.py",
                "FLASK_ENV": "development",
                "FLASK_DEBUG": "0"
            },
            "args": [
                "run",
                "--host",
                "0.0.0.0"
            ],
            "jinja": true,
            "logToFile": true
        }
    ]
}

If I add "purpose": ["debug-test"] and try to run a test, I get this error:

I've tried setting the env:

            "env": {
                "FLASK_APP": "app.py",
                "FLASK_ENV": "development",
                "FLASK_DEBUG": "0",
                "DEBUGPY_LOG_DIR": "/home/philip/git/"
            },

but I'm still not seeing any debug logs, I'm afraid.

[int19h]

A config with "purpose": ["debug-test"] is basically a template from which the actual config is created when you do "Run Test", so it shouldn't have "program" or "module" in it - that part will be filled in to invoke pytest to run the test you've selected (although this could definitely use better diagnostics on VSCode side!).

You could also try changing the config to invoke pytest directly via "program" and "args", and use F5 to run it instead of Test Explorer - although it might not reproduce then (but that would also be useful to know to diagnose it properly).
