node.js - visual studio code debuggin mocha is ignoring breakpoints

Question

I am trying to debug mocha unit test in visual studio code. I followed this question and got this run configuration:

    {
        "name": "Run mocha",
        "type": "node",
        "program": "/usr/bin/mocha",
        "stopOnEntry": false,
        "args": ["testUtils.js"],
        "cwd": "${workspaceRoot}",
        "runtimeExecutable": null,
        "env": { "NODE_ENV": "development"}
    },

It works. But it does not stop at breakpoints! If I run the file with a normal launch configuration, breakpoints are not ignored.

Any Idea what could be the reason for this?

This works for me, you need to point to _mocha. Using just mocha does not allow attaching breakpoints.

    {
        "name": "Debug mocha",
        "type": "node",
        "request": "launch",
        "runtimeArgs": ["C:\Users\CS\AppData\Roaming\npm\node_modules\mocha\bin\_mocha"],
        "program": "${workspaceRoot}\test.js",
        "stopOnEntry": false,
        "args": [
        ],
        "cwd": "${workspaceRoot}",
        "runtimeExecutable": null,
        "env": {
            "NODE_ENV": "development"
        }
    }
