Download and Install the latest version of Selenium. Download and Install Eclipse IDE for Java. Check if you have Java 8+ on your machine (you would most probably have Java 8+, but its still good to check) 2. Follow the links given below to download and install the latest version of Selenium WebDriver. Download and Install Selenium.The Firefox driver used in earlier versions of Mozilla Firefox Repurposed nuget package of Selenium.WebDriver.ChromeDriver but for Firefox Driver instead Install Firefox Driver(Win64) Marionette. Grid 1Gecko (Marionette) Driver Selenium: Download, Install, Use with , Selenium Webdriver version 2.53 is not compatible with Mozilla Firefox version 47.0+. If after.Following are the main differences between Selenium Grid 1 and 2. But since version 3.0.2 the documentation explicitly states you need to install the gecko driver.Above that from version 47 you would need gecko driver. GeckoDriver acts a link between Selenium WebDriver tests and Mozilla FireFox Browser.Selenium Grid 2 is now bundled with the Selenium Server jar fileAnswer: Firefox version 46. 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. They are two different programs.Selenium WebDriver version 2.53 is not compatible with Mozilla FireFox version 47.0+.There can be one or more nodes in a grid. Nodes are the Selenium instances that will execute the tests that you loaded on the hub. The machine containing the hub is where the tests will be run, but you will see the browser being automated on the node. The hub is launched only on a single machine, say, a computer whose O.S is Windows 7 and whose browser is IE. There should only be one hub in a grid. The hub is the central point where you load your tests into.
![]() On the command prompt, type java -jar selenium-server-standalone-2.30.0.jar -role hub Using the command prompt, navigate to the root of Machine A’s – C drive, because that is the directory where we placed the Selenium Server. We are now going to launch a hub. The following steps will launch the hub and the node. Go to Machine B and launch a command prompt there. Now that the hub is already set up, we are going to launch a node. Since Machine A’s IP address is 192.168.1.3, then on the browser on Machine B you should type Simply open up a browser and go to Also, you can check if Machine B can access the hub’s web interface by launching a browser there and going to where “iporhostnameofmachineA” should be the IP address or the hostname of the machine where the hub is running. Selenium Grid, by default, uses Machine A’s port 4444 for its web interface. Your command prompt should look similar to the image belowAnother way to verify whether the hub is running is by using a browser. Textwrangler for mac download freeNOTE: You now have to give path to the Gecko driver if using Firefox. We also used port 5566 though you may choose any free port number you desire. We used the IP address 192.168.1.3 because that is where the hub is running. Which format should i use for external hard drive for mac and windowsTake note of the platform, and the browserName showed by the tooltip.In this case, the platform is “XP” and the browserName is “Firefox.”We will use the platform and the browserName in our WebDriver as shown below (of course you need to import the necessary packages first).Import the necessary packages for RemoteWebDriver and then pass the DesiredCapabilities object that we created above as a parameter for the RemoteWebDriver object.Below is a simple WebDriver Testng code that you can create in Eclipse on Machine A. RemoteWebDriver is used to set which node (or machine) that our test will run against.To use the DesiredCapabilites object, you must first import this packageTo use the RemoteWebDriver object, you must import these packages.Go to the Grid’s web interface and hover on an image of the browser that you want to automate. DesiredCapabilites is used to set the type of browser and OS that we will automate When you press Enter, your command prompt should be similar to the image below.Designing Test Scripts That Can Run on the GridTo design test scripts that will run on the grid, we need to use DesiredCapabilites and the RemoteWebDriver objects. Which Gecko Should We For Selenium 2.53 On Drivers For EachURL followed by ‘Nodes should register to’ on the above screen must be used.Step 6) Grid Console screen will appear which indicates the hub is up and runningStep 1) Download the sample node configuration file provided by Selenium using the below URLNOTE: IF YOU ARE USING SELENIUM 3.0 OR ABOVE, THE BELOW JSON FILE MUST BE USEDStep 2) Copy and paste the code into a text editor such as Notepad and save the file with the extension ‘.json’Run the below command on command prompt Java-Dwebdriver.chrome.driver="chromedriver.exe" -Dwebdriver.ie.driver="IEDriverServer.exe" -Dwebdriver.gecko.driver="geckodriver.exe" -jar selenium-server-standalone-2.53.1.jar -role node -nodeConfig node1.jsonNOTE: Before running the command, please make sure the drivers for each of the browsers have been downloaded onto local machine directoryStep 4) The below screen will appear when enter key is pressedStep 5) Navigate to the grid console to verify if the nodes have been successfully configuredThe browsers are displayed on the grid console. Selenium has an in built JSON config file that can be used to set up selenium grid.Below are the steps to configure selenium grid using JSON config file.Step 1) Download the code for JSON config file using the below path"capabilityMatcher": "org.openqa.grid.internal.utils.DefaultCapabilityMatcher","registryClass": "org.openqa.grid.internal.DefaultGridRegistry",Step 2) Copy and paste the code on a text editor such as Notepad with the extension ‘.json’Step 3)Launch the hub using the below command using command prompt java -jar selenium-server-standalone-2.53.1.jar -role hub -hubConfig hubconfig.jsonNOTE: Selenium stand alone jar file and the json file must be present on the same directoryStep 4) The below screen will appear which indicates the hub is set up successfullyStep 5) Open web browser and try connecting to the below URL NOTE: The URL may vary from machine to machine. It is a standard format used for interchange of data between browser and the web server.
