How do I use PYTHONPATH correctly for debugging test?

[rishacha]

I want to debug pytest using PYTHONPATH=src in the vscode debug ui and it doesn't work. Can someone help me out?

My settings.json for the workspace look like this -

{
    "python.testing.pytestArgs": [
        "tests"
    ],
    "python.testing.unittestEnabled": false,
    "python.testing.unittestArgs": [
        "-v",
        "-s",
        "./tests",
        "-p",
        "test_*.py"
    ],
    "python.testing.pytestEnabled": true,
    "python.envFile": "${workspaceFolder}/.env",
    "terminal.integrated.env.linux": {
        "PYTHONPATH": "${workspaceFolder}/src;${workspaceFolder}/tests"
    }
}

.env file

PYTHONPATH=src

You can set env or envFile in your launch.json config.
