I think my local stratgey is not called passport js and nodejs

auth.js

var express = require('express');

var morgan = require('morgan');
var app = express(); 

require('./db/passport')(passport);


var colors = ["red", "orange", "yellow", "olive", "green", "teal", "blue", "violet", "purple", "pink", "brown"];



router.get('/login', function(req, res, next) {
  res.render('auth/login', { title: 'URKC Login', color: colors[Math.round(Math.random() * colors.length)] });
});


router.get('/register', function(req, res, next) {
  res.render('auth/register', { title: 'URKC Registration', color: colors[Math.round(Math.random() * colors.length)]  });
});



router.post('/register', passport.authenticate('local-signup',{

I am trying to test my signup function in passport.js so i put post on auth.js, but I think it is not getting called and always send failureRequest. I put some console on function in passport.js to see weather it is getting called or not, but it is not printing any console log when it is post.
