What is Selenium• Is a suite of tools to automate web browsers across many platforms

• Can be used for– Automate web application for testing– Automate web administration tasks– Measure Performance– Test Security

• Supports multiple browsers, platforms and Languages– Chrome, IE, Firefox, Opera, Safari, – HTML Unit, Android & iOS phones and tablets– Java, C#, Ruby, Python, PHP, Perl, etc.

• Deploys on – Windows, Mac, Linux

• Variants – Selenium 2 (Webdriver) , Selenium 1 (Remote Control), Selenium IDE


Selenium - History• Started in 2004 in by Jason Huggins

who worked in ThoughtWorks• Jason joins Google in 2007• Currently CTO of SauceLabs• Simon Stewart Started work on

Webdriver in Google• http://google-

Growing importance of Selenium


Need of Test Automation• Frequent regression testing• Rapid feedback to developers• Virtually unlimited iterations of test case

execution• Support for Agile and extreme development

methodologies• Disciplined documentation of test cases• Customized defect reporting• Finding defects missed by manual testing


Selenium IDEPros

– Easy to install as a Firefox plugin– Record & Playback– Easy Execution– Export script– Suitable for creating simple scripts

Cons– Sequential Execution– Not easy to data drive– No basic Programming Construct


Selenium IDE


Selenium RC


Selenium RC• Client-server architecture• It ‘injects’ javascript functions into the browser. Uses

its javascript to drive the AUT

Problems• browsers impose a pretty strict security model on any

JavaScript to protect a user from malicious scripts. • Examples

– trying to upload a file (IE prevents JavaScript from changing the value of an INPUT file element)

– when trying to navigate between domains (because of the single host origin policy problem)


Selenium WebDriver• Makes direct calls to the browser using each

browser’s native support for automation– For Firefox, implemented as an extension– For IE, makes use of IE's Automation controls

• Circumvents JavaScript security restrictions• Can make use of facilities offered by the OS

– More closely model how the user interacts with the browser, and that we can type into "file" input elements

• Support by browser vendors - Opera, Mozilla and Google are all active participants

Sample Webdriver Test


Why choose Webdriver• Object Oriented, smaller, compact API - This can

make it easier to work with compared to RC• Mimics the way that your users work with your

site and apps • Offers advanced user interactions APIs

– Drag and Drop– Clicking multiple elements with Control key

• Support for WebDriver is baked into the browser itself: your tests run fast and are stable


Issues

• Changing element locators• Changing data• Reusability• Maintainability• Readability• Reporting


Need framework to…• Allow organizing tests into different Pages • Abstract element locators• Abstract data• Allow verification points• Capability to deal with file system\databases\

windows dialogs, etc.• Be maintainable to keep pace with fast agile

development
