When I run mocha tests I always get Error: connect ECONNREFUSED

Question

I'm trying to run my app tests with mocha and supertest but I always get Error: connect ECONNREFUSED.

app.js code:

var express = require('express'),   mongoose = require('mongoose'),   fs = require('fs'),   config = require('./config/config');  mongoose.connect(config.db); var db = mongoose.connection; db.on('error', function () {   throw new Error('unable to connect to database at ' + config.db); });  var modelsPath = __dirname + '/app/models'; fs.readdirSync(modelsPath).forEach(function (file) {   if (file.indexOf('.js') >= 0) {     require(modelsPath + '/' + file);   } });  var app = express();  require('./config/express')(app, config); require('./config/routes')(app);  app.listen(config.port);  exports.app = app; console.log('LISTEN ON http://localhost:3000/') 

test.js code:

var should = require('should');  var assert = require('assert'); var request = require('supertest'); var mongoose = require('mongoose'); var app = require('../../../app').app;  describe('Categories', function() {     it('- POST is testing', function(done) {         request(app)         .post('http://localhost:3000/categories')         .send({title:'test', text:'test'})         .end(function(e, res) {             console.log(e, res);         });     }); }); 

Test output:

LISTEN ON http://localhost:3000/     Categories { [Error: connect ECONNREFUSED]   code: 'ECONNREFUSED',   errno: 'ECONNREFUSED',   syscall: 'connect' } undefined     1) - POST is testing     0 passing (2s)   1 failing  Done, but with warnings. 

Could you give any clue why this happend?

Thank you in advance!

Answer 1

The problem was the path. Replacing "localhost:3000/categories" by this "/categories" all works fine.

Working example:

describe('Categories', function() {     it('- POST is testing', function(done) {         request(app)         .post('/categories')         .send({title:'test', text:'test'})         .end(function(e, res) {             console.log(e, res);         });     }); });

I'm facing same problem, and find out the problem is- only the path url. Path should be in this way -

.post('/categories')
