Possible to tell nodeunit not to finish a particular test until test.done() is called?

Question

I am doing some async testing with nodeunit and I was wondering whether it is possible to tell nodeunit to not terminate test cases until test.done is called.

Basically this is how my test cases looks like right now:

exports.basic = testCase({

  setUp: function (callback) {
    this.ws = new WrappedServer();
    this.ws.run(PORT);
    callback();
  },

  tearDown: function (callback) {
    callback();
  },

  testFoo: function(test) { 
    var socket = ioClient.connect(URL);
    socket.emit('PING', 1, 1);
    socket.on('PONG', function() { 
      // do some assertion of course
      test.done();
    }); 
  }
});

The problem now is that PONG is not sent back quick enough for the test code to be executed. Any ideas?

I just had a very similar problem, hence I was browsing this question. In my case the server (analogous to your WrappedServer) was throwing an exception, causing the test to exit abruptly without hitting my event handler with test.done(). I think it is rather rude of nodeunit to swallow the exception without a peep.

I had to resort to the debugger to find the problem, which if you haven't done before, I can save you a web search: node --debug-brk node_modules/nodeunit/bin/nodeunit your_nodeunit_test.js
