How to test app connection with express, nodeJS and Mocha

I've got my app properly configured, such that if I run node app.js everything starts up. I'm trying to test for the connection of my app is working properly using unit tests. What I have so far is:

var options = {
    url: 'http://localhost',
    port: 8080,
};
var app =  require("../app.js");
var should = require('should'); 
var assert = require("assert");
var async = require('async');

it ('tests the ok connection of the app by checking that it is listening on port 8080', function(dont) {
  request(options,app)
    .get('/')
    .expect(200)
    .end(function (err, res) {
    res.header['location'].should.include('/')
    res.text.should.include('Listening on port 8080');
  done();
  });
});

I was getting the error message Error: options.uri is a required argument, which is why I added the var options. Now I'm getting error message TypeError: Object #<Request> has no method 'get'.

How can properly check that I have a good connection (200), that i'm on the right page ('/') and that it is logging the message Listening on port 8080 upon connection?

Thanks!
