Mocha-Express unit test fails with localhost as URL

I have written the following script (server.js):

var express = require('express'),
    app = express(),
    server;

app.get('/', function (request, response) {
  response.send('This is the main page.\n');});

exports.listen = function (port){
    server = app.listen(port, function () {
    console.log('Server available listening at: ' + port);}) };

exports.close = function () {
  server.close(function (){
    console.log('Server Closed')}); };

and the following Mocha unit test (test.js):

var server = require ('./server'),
    assert = require ('assert'),
    http = require ('http');
var port = 8085;

describe('server', function () {
  before(function () {
    server.listen(port)});

  after(function () {
    server.close();}); });

describe('Server status and Message', function () {
  it('status response should be equal 200', function (done) {
    http.get('http://127.0.0.1:8085', function (response) {
         assert.equal(response.statusCode, 200);
        done(); }); }); });

When I run the test.js passing either 'localhost:8085' or '127.0.0.1:8085' to http client, with whatever port, Mocha show the following error:

1) Server status and Message status response should be equal 200:
     Uncaught Error: connect ECONNREFUSED
      at exports._errnoException (util.js:746:11)
      at TCPConnectWrap.afterConnect [as oncomplete] (net.js:983:19)

But I can connect the server perfectly via http client wiht the same localhost url (listener.js):

var server = require('./server');
var http = require('http');

    var url = 'http://localhost:8085';
    var content = function(response){
        response.setEncoding("utf8");       
        response.on("data", function(data) {
                console.log(data)});}

    server.listen(8085);
    setTimeout(function (){server.close();}, 3000)

    http.get(url, content);

I have tried running the unit test with others internet url's as 'https://www.google.com.co/' (the test doesn't pass but works) and the test runs correctly.

Could you help me with this issue. Thanks you a lot.

You're accidentally running two sets of tests. Move the second describe() inside the first one so it can rely on the before() hook, like this:

var server = require ('./server'),
    assert = require ('assert'),
    http = require ('http');
var port = 8085;

describe('server', function () {
    before(function () {
        server.listen(port);
    });

    after(function () {
        server.close();
    });

    describe('Server status and Message', function () {
      it('status response should be equal 200', function (done) {
            http.get('http://127.0.0.1:8085', function (response) {
                  assert.equal(response.statusCode, 200);
                  done();
            });
       });
    });
});
