Hub – Hub will be the central machine which will redirect the commands to the respective node based on parameter To understand the Selenium grid we need to understand HUB and NODE concept which will actually help you to create grid environment. Let me explain through an example- Let’s say you have 1 script which you need to run on MAC, Linux, Unix and Windows then you have 2 approaches.ġ- Setup the complete infrastructure in every machine to run test (not recommended)Ģ- Setup the grid environment to run test on all platform with the help of Node and Hub concept (Recommended) Selenium grid will actually help you run the test on multiple nodes which will reduce the total execution time which is the main advantage of Test Automation. Selenium grid is the concept which will allow you to run your test on multiple machines and on multiple browsers. We can use Selenium Grid for remote execution on the different platform.This article will Guide you how to use Selenium grid in selenium webdriver. Let’s see, for Selenium 2.53.1 and before, how Selenium used to work with FireFox.Selenium grid has introduced in Selenium RC itself and it is known as Selenium Grid 1.0 if you are using with Selenium RC. It is a web browser engine which is inbuilt in FireFox Browser.īut here comes the question, why only GeckoDriver as opposed to FireFox’s default driver.The Answer to which is GeckoDriver uses W3C WebDriver protocol to communicate with Selenium, which allows Selenium Developers to allow the same WebDriver to run in multiple browser versions. GeckoDriver acts a link between Selenium WebDriver tests and Mozilla FireFox Browser. GeckoDriver is a proxy for using W3C WebDriver-compatible clients to interact with gecko-based browsers i.e. After v47.0, FireFox is provided with GeckoDriver. Selenium WebDriver version 2.53 is not compatible with Mozilla FireFox version 47.0+. But after Selenium3, by using GeckoDriver explicitly, we can initialize the script in FireFox.įireFox was fully supported only in previous versions i.e. Before Selenium3, Firefox used to be the default browser for Selenium. Compatibility of Firefox with Selenium has always been a pain area.
