在节点检查器中运行超级测试时，无法读取null的属性“ _host”

Question

I'm fairly new to the Angular world and have been using the angular-fullstack generator + Yeoman to build out a project. I'm using Sublime (not Webstorm) and have been trying to figure out how to set up the project so that I can debug the mocha tests from the terminal, but am hitting a wall.

Here's the default things.spec.js that's generated with 'yo angular-fullstack' with a debugger statement added in.

var should = require('should');
var app = require('../../app');
var request = require('supertest');

describe('GET /api/things', function() {
   it('should respond with JSON array', function(done) {
       request(app)
          .get('/api/things')
          .expect(200)
          .expect('Content-Type', /json/)
          .end(function(err, res) {
              debugger;
              if (err) return done(err);
              res.body.should.be.instanceof(Array);
              done();
          });
   });
});

By combining advice from the grunt-mocha-test documentation and this SO answer , I've updated the test script in package.json as follows:

"scripts": {
    "test": "node-debug <PATH TO GRUNT-CLI>\\grunt test"
}

When I run 'npm test', node-inspector successfully boots up a browser instance and attaches the debug session to my test process. However, when I press "continue", the debugger breakpoint is NOT hit and the test fails with the following stack. Anyone have any clues as to what's causing this?

TypeError: Cannot read property '_host' of null

This looks like a bug in Node Inspector. https://github.com/node-inspector/node-inspector/issues/698
