mocha chai test on node api always recive 404 status

I am creating this test file

let chai = require('chai');
let chaiHttp = require('chai-http');
let server = require('../index');
chai.use(chaiHttp);

describe('Users', () => {
  describe('/GET users', () => {
    it('it should GET all the users', (done) => {
      chai.request(server).get('/user/get-all-users').end((err, res) => {
          res.should.have.status(200)
          done()
        });
    });
  });
});

This route works just fine, but when running on test I always get test failure 404

I am using restify for running my server,

global.server = restify.createServer({
    url     : config.base_url,
    name    : config.name,
    version : config.version,
    log     : bunyanWinston.createAdapter(log),
  })
