Stephen Mallette commented on TINKERPOP-2409:
---------------------------------------------

I don't seem to be able to get a hanging situation on 3.4.8. By "no connection" i assume i could recreate that by just not having Gremlin Server running. Is that right? That said, when I do that I don't get an error or anything...it just sorta "does nothing". I'm not always smart about javascript, but this was my test:

{code}
describe('Faulty Traversal', function () {
  describe("No Server Available", function () {
    it('should not hang', function() {
      const authenticator = new PlainTextSaslAuthenticator('no', 'matter');
      const g = traversal().withRemote(new DriverRemoteConnection('ws://localhost:9998/gremlin', {authenticator}));
      g.V().toList().then(function (list) {
        assert.ok(list);
        assert.strictEqual(list.length, 0);
      }).catch(function(err) {
        assert.fail();
      });
    });
  });
});
{code}

It just passes without error - sorta expected the {{catch()}} to do something, but i might not be doing something right. [~jorgebg] any thoughts on this one?

> constructor...
>      const authenticator = new PlainTextSaslAuthenticator(userName,dbData.password)
>      this.dc = new DriverRemoteConnection(connectionStrArray.join(''), \{ authenticator })
>     this.graph = new Graph()
>   
>  function code...
>      const g = this.graph.traversal().withRemote(this.dc)
>        let count = await g.V().count().next()
>        console.log(count)
>   
>  This works great with a connection but with no connection it failed with a crash error in 3.3.8 - not ideal  but was manageable as code is always run as a dynamic object per. In 3.4.8 when there is no connection it never resolves or times out so it just hangs. 
> I haven't found a work around as yet
