Issue: Debugger hangs when debugging pytest tests on gevent based code

Steps to reproduce:

1. Clone repo from https://github.com/sradhakrishna/test-nameko
2. Open workspace, set Automatic tasks on Folder Open task
3. Relaunch workspace; should setup a virtualenv .venv in the root folder. (Refer to .setupworkspace.sh for details)
4. Open test_serviceb.py, set a breakpoint in test_event_interface, and launch debug test from test pane.
5. You'll notice that the debugger hangs.

Expected behavior: Should be able to launch debug sessions from tests pane.

in your launch json do you use gevent = true? see here microsoft/debugpy#515 (comment)

[sradhakrishna]

I am trying to launch debug test from the Test panel. How do I set gevent = true for that "debug test" configuration? Can you please help with instructions for this?

…

@sradhakrishna Add a configuration like this:

        {
            "name": "(test debug only)",
            "type": "python",
            "request": "launch",
            "gevent": true,
            "purpose": ["debug-test"]
        }

[sradhakrishna]

Added configuration here: https://github.com/sradhakrishna/test-nameko/blob/0259b45b4b269fafbb7de699d293ee446bfaae2c/workspace.code-workspace#L20.

Is this right? I am still not able to debug code - the debugger is still hanging.

For whatever its worth, here's the output of pip freeze:

Am I missing anything?

[karthiknadig]

That won't work, we don't pick up the debug configuration from the settings. you have to add it to the launch.json file.

We have an issue open to load the config for tests from settings. (microsoft/vscode-python-debugger#525)

[sradhakrishna]

I've moved launch configurations to launch.json - and am able to debug now! Thanks a lot, @karthiknadig !

Will follow progress on microsoft/vscode-python-debugger#525.

[sradhakrishna]

Am closing this issue as resolved. Thanks again!
