codeceptjs - Error: Couldn't connect to selenium server / A session id is required for this command but wasn't found in the response payload

I used this quick start guide to install this test framework: https://github.com/codeception/codeceptjs/ .

After successful installation I edited my "mytest_test.js" with following additions:

Feature('CodeceptJS Demonstration');

Scenario('test some forms', (I) => {
  I.amOnPage('http://simple-form-bootstrap.plataformatec.com.br/documentation');
  I.fillField('Email', 'hello@world.com');
  I.fillField('Password', '123456');
  I.checkOption('Active');
  I.checkOption('Male');
  I.click('Create User');
  I.see('User is valid');
  I.dontSeeInCurrentUrl('/documentation');
});

Afterwards I started my test:

codeceptjs run --debug

My results are:

C:\laragon\www\codeceptjs2  (codeceptjs2@1.0.0) 31.01.2017 10:46:30,41

I don't get any screenshots in the output folder and this framework doesn't work and I don't understand why.

steps_file.js

'use strict';
// in this file you can append custom step methods to 'I' object

module.exports = function() {
  return actor({

    // Define custom steps here, use 'this' to access default methods of I.
    // It is recommended to place a general 'login' function here.

  });
}

Solution

For a quickstart with CodeceptJs I would recommend you to use Nightmare helper. So in codecept.conf you should have something similar to this

'helpers': {
        'Nightmare': {
            'url': 'http://localhost:3000',
            'waitForTimeout': 10000,
            'show': false
        }
    },

And don't forget to install nightmare

 npm install --save-dev nightmare nightmare-upload
