I've made this work on VSCode on OS X 10.10. Just replace your ./settings/launch.json file with this.

{
    "version": "0.1.0",
    "configurations": [
        {
            "name": "Run app.js",
            "type": "node",
            "program": "app.js", // Assuming this is your main app file.
            "stopOnEntry": false,
            "args": [],
            "cwd": ".",
            "runtimeExecutable": null,
            "env": { "NODE_ENV": "production"}
        },
        {
            "name": "Run mocha",
            "type": "node",
            "program": "/Users/myname/myfolder/node_modules/mocha/bin/_mocha",
            "stopOnEntry": false,
            "args": ["test/unit.js"],
            "cwd": ".",
            "runtimeExecutable": null,
            "env": { "NODE_ENV": "production"}
        }
    ]
}

It is also available as a gist here.

The key values you need to change are program, which should be set to the _mocha executable, and args, which should be an array of your test files.
