  • 3. Open Source Software Open Source Software (OSS) is computer software with it Source code made available & licensed with an open source license in which the copyright holder provides the rights to study, change & distribute the software to anyone & for any purpose. Test Automation Test automation is the use of Special Software to control the execution of tests and the comparison of actual outcomes to predicted outcomes. Framework A framework is an integrated system that sets the rules of automation for a specific product 23/02/2013 Selenium Open Source Test Automation Tool 3
  • 4. Generations of Various Framework & Scripting techniques 1st Generation: Linear – Procedural code, possibly generated by tools, such as record & playback scripting. 2nd Generation: Structured – Use control structures, if-else, switch, for, while conditions / statements. 3rd Generation: Data driven – Test script data persist outside the script in DB, spreadsheet, cvs, etc. 4th Generation: Keyword driven – Test script instructions / statements persist in spreadsheet, property files. 5th Generation: Hybrid – two or more of the patterns above are user, its also called as script less automation (less scripting) 23/02/2013 Selenium Open Source Test Automation 4
  • 5. What is Selenium  Selenium is an open source testing tool for automating web based applications.  It can automate only web based applications.  It works on multiple browsers and multiple operating systems.  Helpful to distribute/scale your test cases across multiple platforms.  Being open source and very strong in nature, demand for this tool is increasing. Components of Selenium     Selenium IDE Selenium 1 (Remote Control) Selenium 2 (WebDriver) Selenium Grid 23/02/2013 Selenium Open Source Test Automation Tool 5
  • 6. Benefits of Selenium  Open source  Works on multiple browsers  Works on multiple Operating Systems  Supports many languages for scripting  Supports to tests Ajax Applications, Flash Applications & Database Testing  Multiple test frameworks are supported (Junit4, TestNg, Data driven, Keyword driven, Hybrid, etc)  Can be used for Functional, Regression & Browser compatibility testing 23/02/2013 Selenium Open Source Test Automation Tool 6

  • 8. You need to download & configure the required library from the url http://seleniumhq.org/download/ 23/02/2013 Selenium Open Source Test Automation Tool 8
  • 9. 23/02/2013 Selenium Open Source Test Automation Tool 9
  • 10. http://seleniumhq.org/ The official website of Selenium, contents of the web site Projects:     Selenium IDE Selenium Remote Control Selenium WebDriver Selenium Grid Downloads: You can find the latest releases of all the Selenium components Documentation: Complete Selenium Documentation with Programming Language Preference to Java, C# (Csharp), Python, Ruby, Php, Perl Support: Getting Help, User Group, Chat Room, Bug Tracker, Commercial Support About Selenium: News/Blog, Selenium Events, Who made Selenium, History, Roadmap, Get involved, Documentation. Selenium sponsors. 23/02/2013 Selenium Open Source Test Automation Tool 10
  • 11. Selenium IDE (Integrated Development Environment)  The IDE is a record and playback tool with built-in debugger and editor  The IDE is an add-on for Mozilla Firefox only, works only on Firefox.  The IDE automatically creates test scripts in the Selenese HTML table format  The IDE can generate code into a wide variety of languages and test frameworks. Such as HTML Selenese, C#, Java, Perl, PHP, Python, Ruby, Bromine, JUnit, NUnit, RSpec, Test::Unit, TestNG, etc. 23/02/2013 Selenium Open Source Test Automation Tool 11
  • 12. Selenium IDE (Firefox plug-in tool) 23/02/2013 Selenium Open Source Test Automation Tool 12
  • 13. Selenium RC 23/02/2013 Selenium Open Source Test Automation Tool 13
  • 14. Selenium WebDriver  WebDriver is designed to providing an simpler, more concise programming interface along with addressing some limitations in the Selenium-RC API (Application Program Interface).  Selenium-WebDriver was developed to better support dynamic web pages.  Selenium-WebDriver makes direct calls to the browser using each browser’s native support for automation.  You may, or may not, need the Selenium Server, depending on how you intend to use Selenium-WebDriver. 23/02/2013 Selenium Open Source Test Automation Tool 14
  • 15. Flow of Selenium RC Selenium selenium = new DefaultSelenium("localhost",4444, "*chrome", “http://www.nie.ac.in"); Flow of Selenium Web Driver 23/02/2013 Selenium Open Source Test Automation Tool 15
  • 16. Selenium Web Driver flow for Chrome & IE browser public static WebDriver driver; driver = new ChromeDriver(); public static WebDriver driver; driver = new InternetExplorerDriver(); 23/02/2013 Selenium Open Source Test Automation Tool 16
  • 17. Selenium Grid • The Grid distributes your tests on multiple machines so that you can run your tests in parallel – Tests can be ran in parallel for reduced execution time – Test can be ran on various browser and operating system combinations – Generates a collated report from all test machines • The Grid can be run on a server farm or in the Cloud – The tests are distributed by the Hub server to multiple Selenium RC machines – The tests can be ran by various Cloud computing services such as Amazon EC2, Sauce Labs, BrowserMob, and PushToTest – The Grid is written in Java for portability and is executed from the command line 23/02/2013 Selenium Open Source Test Automation Tool 17
  • 18. Selenium Grid 23/02/2013 Selenium Open Source Test Automation Tool 18
  • 19. Selenium Grid - Concept Selenium Grid can be used to run multiple instances on various operating system and browser configurations. 23/02/2013 Selenium Open Source Test Automation Tool 19
  • 20. Why choose Selenium? • • • • The Selenium client libraries can be imported into most popular language IDE’s – Eclipse, NetBeans, Visual Studio .NET, etc. – Reuses existing unit testing frameworks – Integrated into Fitnesse frameworks Used by QA test teams for functional, regression, and user acceptance testing (UAT) Integration into the build process has made it easy to deploy into Continuous Integration Environments Used by Developers for test driven development (TDD) in the Agile and extreme programming (XP) community 23/02/2013 Selenium Open Source Test Automation Tool 20
  • 21. Why choose Selenium? • Expanded usage by Developers into other areas – Conversion into production monitoring and load testing – Extended hooks into Flash, Flex, and other popular technologies • Strong support for AJAX technologies • Cross platform browser and operating system comparison testing • Run tests in parallel – Using the Grid tests can be run in parallel across multiple RC (agent) machines from a single Hub machine – Saves time, and runs faster 23/02/2013 Selenium Open Source Test Automation Tool 21
  • 22. Why choose Selenium? • Selenium is FREE! – No licensing costs, so it can be deployed to as many machines as needed in a lab or for local development – No maintenance renewal costs • Use Cloud computing services – If hardware is a limited, then opt to have a remote test lab in the Cloud as needed – Amazon EC2 (functional, regression testing) – Sauce Labs (functional, regression testing) – BrowserMob (production monitoring, load testing) – PushToTest (production monitoring, functional testing, load testing) 23/02/2013 Selenium Open Source Test Automation Tool 22

  • 24. Integration with Java and .NET Java .NET • • • • • Object oriented – Design and programming TestNG/JUnit – Common unit test framework Ant/Maven – Automatically build, deploy, and test application Bamboo/Hudson – Continuous integration – Automated test reporting/notification 23/02/2013 • • Object oriented – Design and programming VSUnit, NUnit, MBUnit – Common unit test framework TFS Build – Automatic build verification tests (BVT) – Continuous integration – Automated test reporting/notification Selenium Open Source Test Automation Tool 24
  • 25. Integration with Java and .NET Java .NET • • Spring /Struts – Integrates with application – Interface with Java components – Interface with Web services – Access Oracle/MySQL databases 23/02/2013 .NET Framework – Integrates with application – Interface with .NET components – Interface with Web services – Access SQL Server databases Selenium Open Source Test Automation Tool 25
