/**
 * Ugly hack
 *
 * Reasoning:
 * 
 *     We cannot define the driver as Singleton for performance reasons. One driver is created synchronously after the other.
 *     When we run in parallel, all the tests queue up, and for example, an android takes 50 seconds to be created on SLabs.
 * 
 * 
 *     We create the first Driver at the beginning of the set up and we assign it with the setter here. Since this class
 *     is Singleton, all the other classes gets this provider, and since the very first thing the test does on the setup
 *     is to set the driver her, all the rests providers will get this one.
