How to debug VMs

[Josef37]

I've been looking into #121 yesterday and tried to set up some tests to verify wrong/right behavior.

Therefore I had to create a few mocks in roomsSpec.js, but couldn't find out what these values should be.

My idea was to debug the script when its running to get some useful mocks, but I can't get my IDE (VSCode) to debug those...

I've seen there is a config option editor.enableInspector so I figured you have set this up once.
Can you help me set up debugging?

PS: That's where I'm currently at in terms of mocking values

let globals = {};

beforeEach(() => {
  const runtimeData = {
    staticTerrainData: require("../../helpers/mocks/rooms").terrain,
  };
  const register = {
    wrapFn: fn => fn,
    rooms: { E2S7: {} },
    _useNewPathFinder: true,
  };

  rooms.make(runtimeData, {}, register, globals);
  rooms.makePos(register);

  for (var i in runtimeData.rooms) {
    register.rooms[i] = new globals.Room(i);
  }
});

But calling RoomPosition.findClosestByPath still results in the following issue, since globals.PathFinder is not set.

Message:
    TypeError: Cannot read property 'search' of undefined

Did you manage to get the enableInspector to work? Did it work out of the box for you, to at least inspect the values in the VM?

There's an example of using the inspector here: https://github.com/laverdet/screepsmod-inspector
