Selenium is a tool for automating web application testing. It supports recording tests in Selenium IDE and playing them back, and also allows tests to be written in programming languages and executed via Selenium Remote Control. Tests can run across different browsers and machines in parallel using Selenium Grid. The key components of Selenium are IDE, Remote Control, Grid, and the underlying Selenium Core libraries.

- 2. What is Selenium? Selenium is a robust set of tools that supports rapid development of test automation for web-based applications. Works on every system, where JavaScript is supported Can simulate a user navigating through pages and then assert for specific marks on the pages Selenium IDE is a plug-in to Firefox to record and playback tests. (like Win Runner, QTP). You can then export the recorded test in most language e.g. HTML, Java , C# , Perl , Ruby etc. Ability to deploy on different platforms : Windows, Linux, Mac.

- 5. Selenium Core Legacy product that consisted of libraries of .js(JavaScript) files. Selenium Core is a test tool for web applications. Selenium Core tests run directly in a browser, just as real users do. And they run in Internet Explorer, Mozilla and Firefox on Windows, Linux and Macintosh. Installation 1. Extracting the Selenium Core zip file into the DocumentRoot, or webroot of your webserver. 2. Then, try to open the TestRunner.html page on your website, which should be in the core/ directory.
- 6. Selenium IDE Integrated Development Environment for building Selenium test cases. Operates as a Firefox add-on and provides an interface for developing and running individual test cases or entire test suites. Selenium-IDE has a recording feature, which will keep account of user actions as they are performed and store them as a reusable script to play back. Installation 1. Open Firefox and Download the latest version of Selenium IDE (currently version 1.9).
- 7. Selenium IDE cont… Start Screen Recording a script
- 8. Selenium Remote Control (RC) Selenium Remote Control (RC) is a server, written in Java that accepts commands for the browser via HTTP. Components of Selenium RC are: o Selenium Server o Client Libraries Installation 1. The Selenium RC server is simply a Java jar file (selenium- server-standalone-<version-number>.jar) 2. Just downloading the zip file and extracting the server in the desired directory is sufficient.
- 9. Selenium Grid Selenium-Grid allows you run your tests on different machines against different browsers in parallel. Selenium-Grid support distributed test execution. With Selenium Grid, one server acts as the hub. A grid consists of a single hub, and one or more nodes. Both are started using the selenium-server.jar executable. Installation 1. Download the Selenium-Server jar file 2. Install it in a folder of your choice.
- 10. Advantages And Limitations Advantages: Customized defect reporting Finding defects missed by manual testing Support for Agile and extreme development methodologies Frequent regression testing Rapid feedback to developers Limitations: If the application’s user interface will change considerably in the near future, then any automation might need to be rewritten anyway.
- 11. Conclusion Most of the applications these days are Web-Based. Test automation is used more frequently. Test automation uses software tools to run repeatable test. Selenium act as a tool to do test automation. Components include IDE, RC, and Grid. Core Consists of core .js(JavaScript) libraries.
