bengur2, 2021-08-02 13:38:03

Deployed this repository locally:
https://gitlab.com/gitlab-org/project-templates/express

The index.js file replaced:

var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'bengur2' });  // тут вставил ник
});

module.exports = router;

Ran test:
yarn test

Got error:

Error: expected body '<!DOCTYPE html><html><head><title>bengur2</title><link rel="stylesheet" href="/stylesheets/style.css"></head><body><h1>bengur2</h1><p>Welcome to bengur2</p></body></html>' to match /Welcome to Express/

Well, of course, because in the test.js file I see hardcode:

it('has the default page', function(done) {
    request(app)
      .get('/')
      .expect(/Welcome to Express/, done);
  });

What to do with this test?
As for me, it is not usable.
