title: Parallel Execution of Selenium Script on One Physical Machine
body: <p>I have a hybrid framework based on Selenium WebDriver. It is taking around 2-3 hours to run the test suite I have right now. What is the best way to start running the tests parallel <strong>On the same machine</strong> (Even if I use Selenium Grid, how many nodes  can I have at max on one machine, provided I also I have to use the same machine as the Hub ?). I have the constraint of using only one physical machine, and I am not using Test NG.</p>
