An Overview of Selenium
This document provides an overview of Selenium, an open source tool for automating web browsers across platforms and browsers. It discusses how Selenium automates all major desktop and mobile browsers using a single script. Selenium includes Selenium WebDriver for controlling browsers programmatically via a REST API, Selenium Grid for distributed parallel testing on different environments, and Selenium IDE, a Firefox add-on for recording and playing back tests without coding. The document traces the history and evolution of Selenium from 2004 to the present and outlines some future directions beyond automated testing capabilities.

- 3. SELENIUM AUTOMATES BROWSERS ALL MAJORBROWSERS ON ALL MAJOR (DESKTOP) OPERATING SYSTEMS
- 4. … AND MOBILE* WEB,NATIVE, AND HYBRID APPLICATIONS * Via appium, Selendroid, ios-driver and WP driver.

- 12. HOW DOES ITWORK? webdriver.xpi XPCOM IEDriverServer.exe COM
- 13. WHAT’S WIRE? A RESTFulweb service using JSON over HTTP. A proposed W3C standard for automating web-browsers. https://code.google.com/p/selenium/wiki/JsonWireProtocol
- 14.
- 15. WHY GRID? Scale bydistributing tests (parallel execution) Run tests against a vast combination of browsers / OS.

- 19. SELENIUM IDE A FirefoxAdd-on for recording, editing and running tests. Over 10M downloads to date! PROS: CONS: • • • • • • • Based on SeleniumCore • No code reuse • No iterations and conditional statements • No exception handling • No error recovery No programming skills required Easy record and playback Step by step debugger Play tests on any browser Export tests as WebDriver tests Extensible
