node.js - Why is address undefined in my app? -


i have simple express app:

var express = require('express'); var path = require('path');  var app = express(); exports.app = app;  var index = require('./routes/index');  app.use(express.static(path.join(__dirname,'client/dist/')));  app.get('/', index.get);  function start(){     var port = process.env.port || 8080;      app.listen(port, function(){         console.log('app running on port: ' + port);     }); };  exports.start = start;

and integration test: 

var request = require('supertest');  var app = require('../app');  describe('get /', function(){     it('should repsond 200', function(done){         request(app)         .get('/')         .expect(200, done.fail);     }); });

the app runs fine, running integration test, following error:

failures:  1) / should repsond 200 1.1) typeerror: object #<object> has no method 'address'

i did searching , seems if app wasn't exported correctly can't seem figure out why.

request(app.app) instead of request(app) in integration test should fix error.

var request = require('supertest'); var app = require('../app');  describe('get /', function(){   it('should repsond 200', function(done){       request(app.app)       .get('/')       .expect(200, done.fail);   }); });
