This document provides an introduction to Selenium, an open source tool for automating web application testing. It discusses the history and components of Selenium, including Selenium RC, WebDriver, Grid, and IDE. Selenium RC and WebDriver are described as the main APIs for controlling browsers. Grid allows running tests on multiple browsers and machines in parallel. IDE is a plugin for recording and playing back tests in Firefox. The document explains how Selenium can test across different browsers, platforms and programming languages. It compares Selenium to other tools like QTP and outlines reasons for choosing Selenium, such as its powerful features, flexibility, support for parallel testing and integration with other tools.
Introduction to selenium
- 2. Agenda Introduction and History What is Selenium Components of Selenium Selenium RC Selenium WebDriver Selenium Grid Selenium IDE Why Selenium over other tools ?
- 3. Introduction Selenium automates browsers. Its open source- Completely Free, all you need is a system and internet. Selenium can be executed on multiple platforms can be controlled by many programming languages and testing frameworks. Support provided from several other open source tools like Jenkins, ANT etc. Can be integrated with several defect tracking tools.
- 4. History Was developed by Jason Huggins in 2004 . He was a working on a in- house project in Thoughtworks. He started working on Selenium Core. Dan Fabulich and Nelson Sproul, Created Selenium RC. Shinya Kasatani in Japan became interested in Selenium, and realised that he could wrap the core code into an IDE module into the Firefox browser, and be able to record tests as well as play them back in the same plugin.
- 5. What is Selenium ? Selenium is a robust tool that supports rapid development of test automation for web-based applications. Can simulate a user navigating through pages and then assert for specific marks on the pages Open source, web-based testing automation tool and cross-browser compliant Open source tool Easy to use
- 7. Selenium Components Selenium Selenium RC Selenium Web Driver Selenium Grid Selenium IDE
- 8. Selenium RC (Remote Control) Selenium-RC provides an API (Application Programming Interface) and library for each of its supported languages: HTML, Java, C#, Perl, PHP, Python, and Ruby. This ability to use Selenium-RC with a high-level programming language to develop test cases also allows the automated testing to be integrated with a project’s automated build environment. Also known as Selenium 1
- 9. How Selenium RC works ?
- 10. Selenium Web Driver Selenium WebDriver is the successor of Selenium Remote Control which has been officially deprecated Selenium WebDriver is a collection of language specific bindings to drive a browser . WebDriver is designed in a simpler and more concise programming interface along with addressing some limitations in the Selenium-RC API. Also Known as Selenium 2 Selenium 1+ Selenium Web Driver = Selenium 2
- 11. Java Ruby PythonC# Perl PHP Language Bindings Selenium Web Driver Browsers IE Firefox Chrome Safari Opera
- 12. Selenium Grid Selenium Grid can run large test suites and test that must be run in multiple environments Tests can be run in parallel with simultaneous execution (different tests on different remote machines) It allows for running your tests in a distributed test execution environment Used to run your tests against multiple browsers, multiple versions of browser, and browsers running on different operating systems It reduces the time it takes for the test suite to complete a test pass
- 14. Selenium IDE If you want to create quick bug reproduction scripts or create scripts to aid in automation-aided exploratory testing, then Selenium IDE is the best. Selenium IDE is an integrated development environment for Selenium scripts Its an add on with firefox. It has record and play back functionality, Though it can record only record on firefox, it can be modified to run in webdriver and RC. The tests can be modified, assertions can be added and test suite can be created.
- 15. Features of Selenium IDE Easy record and playback Intelligent field selection will use IDs, names, or XPath as needed Autocomplete for all common Selenium commands Walk through tests Debug and set breakpoints Save tests as HTML, Ruby scripts, or any other format Support for Selenium user-extensions.js file Option to automatically assert the title of every page
- 17. Why Selenium Over other tools? Most powerful Open Source Automation tool available. Flexible with support to many languages Highly extensible Platform Support– Provides support on wide range of OS compared to any other tool Parallel Testing- Supports parallel Testing Usability – Easy to use. ALM Integration – Provides integration with several bug tracking tools.
- 18. Feature Selenium QTP Record and Play back Yes Yes Language Support Java, C#,PHP,Python,Perl,Ruby VB Script OS Support Windows, Linux, Mac, Andriod, IOS Windows Ease of Execution Easy Easy Browser Support Firefox, IE, Chrome, Opera, Safari IE Support for Defect managenent integration Several Few Addins and Extensions Several Several Cost Free Costly Comparison of QTP over Selenium
