browser browserName = firefox -port 5555ĭ:\JAR\selenium-server-standalone-2.42.2.jar = Location of the Selenium Server Standalone Jar File(on the Node Machine) Java -jar D:\JAR\selenium-server-standalone-2.42.2.jar Step 2 − Launch FireFox Node using the following below command.
We need to point to the selenium-server-standalone JAR while launching the nodes. Step 1 − Logon to the node (where you would like to execute the scripts) and place the 'selenium-server-standalone-2.42.2' in a folder. As of now, we haven't got any nodes, hence we will not be able to see the details. The config of the hub would be displayed as follows. Step 4 − Now click on the 'console' link and click 'view config'. Step 3 − Now open the browser and navigate to the URL http//localhost:4444 from the Hub (The system where you have executed Step#2). Java -jar selenium-server-standalone-2.25.0.jar -port 4444 -role hub -nodeTimeout 1000 Note − Ensure that there are no other applications that are running on port# 4444. Now we will use the port '4444' to start the hub. Step 2 − Start the Hub by launching the Selenium Server using the following command.

Download it by clicking on the version as shown below. Step 1 − Download the latest Selenium Server standalone JAR file from. Let us discuss each of these steps in detail. Develop the Script and Prepare the XML File.Listen below are the major steps involved in this process − In order to work with the Grid, we need to follow certain protocols. The following diagram shows the architecture of Selenium Grid. There can be one or more nodes in a grid which can be of any OS and can contain any of the Selenium supported browsers. Node − Nodes are the Selenium instances that are attached to the Hub which execute the tests. A Selenium Grid has only one Hub and it is launched on a single machine once. Hub − The hub can also be understood as a server which acts as the central point where the tests would be triggered. The selenium-server-standalone package includes Hub, WebDriver, and Selenium RC to execute the scripts in grid.

Selenium Grid allows us to execute multiple instances of WebDriver or Selenium Remote Control tests in parallel which uses the same code base, hence the code need NOT be present on the system they execute. It dramatically accelerates the testing process across browsers and across platforms by giving us quick and accurate feedback.
The recorded test scripts can also be exported to programming languages like C#, Java, Ruby or Python.Selenium Grid is a tool that distributes the tests across multiple physical or virtual machines so that we can execute scripts in parallel (simultaneously). Note: Selenium IDE is available only as Mozilla Firefox and Chrome plug-in, which means you can't record your test cases on browsers other than Firefox and Chrome. You can also refer our JavaScript tutorial provided under the URL: Perhaps, creating test cases on Selenium IDE does not require any programming language but when you get to use selenese commands like runScript, a little knowledge prior to JavaScript would prove beneficial for you to understand the concepts more clearly. Subsequently, you can use the playback option to re-run the test cases. Unlike Selenium WebDriver and RC, it does not require any programming logic to write its test scripts rather you can simply record your interactions with the browser to create test cases. Selenium IDE (Integrated Development Environment) is an open source web automation testing tool under the Selenium Suite. Next → ← prev Selenium Integrated Development Environment (IDE)
