Selenium/Ruby/Inside MediaWiki-Vagrant virtual machine

For this example, we will not enable any roles and we will use MediaWiki core.

Advantages
Running Selenium tests from inside MediaWiki-Vagrant machine has several advantages:


 * You do not have to install anything on your machine, except MediaWiki-Vagrant itself, and it's dependencies.
 * It will also be fast, since the target machine is local.
 * MediaWiki core Selenium test run takes about 3-4 minutes on my machine.
 * It takes about 6-7 minutes for selenium-Core Jenkins job to run.
 * After everything is set up, you do not need internet connection.
 * You are probably already familiar with MediaWiki-Vagrant and have it installed.
 * While the tests are running, you can continue using your machine as usual, because everything is happening inside the virtual machine.

Disadvantages

 * You might not be familiar with MediaWiki-Vagrant, so you will have to learn how to install and use yet another tool.
 * You will have to install MediaWiki-Vagrant and it's dependencies on your machine.
 * The machine is headless (no display) so it is harder to debug failed tests, but not impossible.

Set up MediaWiki-Vagrant

 * Follow instructions at MediaWiki-Vagrant

Install dependencies in the machine
You will need internet access for this step.
