This document discusses Selenium, an open source tool used for automating web application testing. It describes Selenium components like Selenium IDE, RC, and WebDriver. Benefits of Selenium include time savings, reduced costs, repeatable tests, and generated reports. Frameworks like modular, data-driven, and keyword-driven are also covered. The document outlines prerequisites, features, benefits to organizations, best practices, and limitations of Selenium.
Selenium test automation
- 2. Selenium – Testing Tool
- 3. Agenda What is selenium & why? Selenium Components Advantages of Selenium Automating Tests using Selenium Benefits to the Organization Limitations Conclusion
- 4. Test Automation Automation The process of converting manual test cases to test scripts by using automation tools is called as automation The test scripts can be executed on the targeted application whenever required. Advantages Saves time by executing the script without any manual effort We can reduce the cost to the company Test scripts are repeatable Bugs can be identified and accuracy maintained Test report will be generated by the tool and we can ensure quality
- 5. What is Selenium? Selenium is a robust set of tools that supports rapid development of test automation for web-based applications Open source Used for functional regression testing Uses JavaScript Embeds test automation engine in your browser Hooks for many other languages - Java, Ruby, Python Selenium operations are highly flexible & Extendable
- 7. Selenium Components Selenium IDE Integrated Development Environment is for record and run the script. It is an add on for Firefox It is accountable for user’s actions The recorded script can be viewed in all the supported languages The Recorded scripts can be run against other browsers with the help of RC or Web Driver
- 8. Selenium Components Selenium RC RC: Remote Control It is server and it launches all the brewers but one browser at a time It acts as API and Library It is Responsible for the Entire automation It is also known as selenium1
- 9. Selenium Components Selenium Web Driver The advanced version of selenium RC is known as selenium web Driver. The combination of the RC and Web Driver is called as Selenium2.0 Selenium Grid Grid is for parallel Execution We can launch all supported browsers parallel and script can be executed on the targeted browsers parallel
- 10. Selenium Frameworks Definition Frameworks is a combination of classes, Methods, API’s, Libraries these all combined together to work on one application effectively Modular Frameworks Data Driven Frameworks Keyword Driver Frameworks Junit TestNG Hybrid Frameworks
- 11. Selenium Frameworks Modular Frameworks It is basic framework and also linear framework The automation engineer’s will divide the application into modules and sub modules They will develop the scripts for all the modules The scripts are stable they will integrate all the scripts in a hierarchical order to execute
- 12. Selenium Frameworks Data Driven Framework Introduced external files like excel, txt, XML, Database etc.. To take input data as well as to give output result It contains the driver script it is responsible for execution Driver script doesn’t contain any of test cases or test data all the test data and test cases will be available in external file The driver script will take the data from external file and executes hence we call it as data driven framework
- 13. Selenium Frameworks Keyword Driven Frameworks Keyword means step and it is a step by step execution It is very similar to manual testing, so test scripts are similar in the Keyword Driven Framework Types of Keyword Driven Frameworks Junit It is java unit testing framework, the main purpose of junit is to develop the script in java programming language and to execute the scripts once execution is done it auto generates the report result
- 14. Selenium Frameworks TestNG It is testing framework and developed on top of junit they over come all the limitations of Junit in TestNG and introduced some new functionality TestNG is add on for eclipse Hybrid Frameworks The combination of any two or more frameworks is nothing but Hybrid Framework
- 15. Prerequisites Software Selenium IDE, Mozilla Firefox for script recording Selenium Server, Java for running scripts, sikuli Configuration Set path variables Use –multi Window option while starting server Resource Users… should have basic scripting knowledge Hardware… No specific requirement the basic configuration for a server – P4, 512 MB RAM is good enough.
- 16. Features Open source, free software Allows scripting in several languages like Java, C#, PHP and Python. Assertion statements provide an efficient way of comparing expected and actual results. Inbuilt reporting mechanism. Easy Installation Scripting Techniques : Easy recording and playback of scripts Compatibility : Multiple operating systems (Windows, Linux, Mac) Allows cross browser testing Integration with third party tools.
- 17. Benefits to the Organization Automation Benefits Usual benefits for automation e.g. Time saving Time required for sanity reduced ( 12 man hours to 3 man hours, build frequency of 4-5 builds a month ) For one of the projects, Sanity suite automated : 243 test cases Good Returns on Zero Investment Increasing Productivity Cost saving as it is open-source QA engineers get familiar with scripting languages like Ruby, Perl etc apart from manual testing Caveat Full automation and maintenance has not been evaluated and that can be a risk
- 18. Selenium Best Practices Automation Benefits Usual benefits for automation e.g. Time saving Time required for sanity reduced ( 12 man hours to 3 man hours, build frequency of 4-5 builds a month ) For one of the projects, Sanity suite automated : 243 test cases Good Returns on Zero Investment Increasing Productivity Cost saving as it is open-source QA engineers get familiar with scripting languages like Ruby, Perl etc apart from manual testing Caveat Full automation and maintenance has not been evaluated and that can be a risk
- 19. Limitations It does not support and Desktop applications Its and open source tool so in case of any technical issues you need to rely on the selenium community forums to get your issue resolved. You need to know at least one of the supported language very well in order to automate your application successfully. No inbuilt reporting capability so you need plugins like JUnit and TestNG for test reports Lack of exhaustive formal guidance material Note: Selenium Support Desktop applications using Sikuli.
