not working for me, I get : ReferenceError: describe is not defined using the config above.

Didn't work for me - if I add the =xxxx (port number) after --inspect-brk, then I get SyntaxError: .../.vscode/launch.json: Unexpected token / in JSON at position 6.

If I don't add it, it tries port 9229, which is not available, regardless of the separate port: xxxx in the json configuration.

FYI on Win10 (VSC 1.18, node 6.9.4 my current working Debugging config:

    {
	"name": "Run mocha",
	"type": "node",
	"program": "${workspaceFolder}/node_modules/mocha/bin/_mocha",
	"args": ["${workspaceFolder}/test/**/*.spec.js"],
        "request": "launch",
        "outFiles": [
          "${workspaceFolder}/**/*.js"
        ]
    }

Thank you! 😄
