Setting up Selenium Grid Server for parallel execution
To run Selenium WebDriver tests in parallel, we need to set up the Selenium Grid Server as a Hub. The Selenium Server hub will provide the available configurations or capabilities to the Selenium WebDriver tests. The slave machines, also called node, connect to the hub for parallel execution. Selenium WebDriver tests use the JSON wire protocol to talk to the Hub to execute Selenium commands.
The Hub acts like the central point that will receive the entire test request and distribute it to the right nodes.
In this recipe, we will set up a Selenium Grid Server and then add nodes with different OS and browser combinations. We will then use this setup to run tests in parallel using TestNG.
Getting ready
Download the latest Selenium Server standalone JAR file from http://docs.seleniumhq.org/download/. For this recipe, the selenium-server-standalone-2.47.1 version is used.

Setting up a Hub is a fairly simple job. Launch the Selenium...
