5. What is Manual testing? Execution of test cases without using automation tools One of the primitive methods of testing a software Does not require the knowledge of a testing tool Can practically test any application

6. Challenges of manual testing Requires presence of tester at all times Extremely time consuming High risk of error No support for performance and batch testing Manual creation of logs and repositories Limited scope

7. Advent of Selenium Jason Huggins, an engineer at ThoughtWorks, Chicago found the repetitious work of manual testing strenuous and monotonous

8. Advent of Selenium He developed a JavaScript program to automate the testing of a web application

9. Advent of Selenium He developed a JavaScript program to automate the testing of a web application The program was called JavaScriptTestRunner

10. Advent of Selenium He developed a JavaScript program to automate the testing of a web application The program was called JavaScriptTestRunner Initially, the new invention was deployed by the inmates at Thoughtworks. However, in 2004 it was renamed as Selenium and was made open source

13. What is Selenium? Selenium is an automated testing tool used to test web applications across various browsers Open source

14. What is Selenium? Selenium is an automated testing tool used to test web applications across various browsers Open source • Consists of a set of software tools that facilitate testing

15. What is Selenium? Selenium is an automated testing tool used to test web applications across various browsers Open source • Consists of a set of software tools that facilitate testing • Primarily developed in JavaScript

16. What is Selenium? Selenium is an automated testing tool used to test web applications across various browsers Open source Provides a record/playback tool for authoring tests without learning a test scripting language • Consists of a set of software tools that facilitate testing • Primarily developed in JavaScript

17. What is Selenium? Selenium is an automated testing tool used to test web applications across various browsers Provides a record/playback tool for authoring tests without learning a test scripting language Open source • Consists of a set of software tools that facilitate testing • Can be coded in many programming languages • Primarily developed in JavaScript

18. What is Selenium? Selenium is an automated testing tool used to test web applications across various browsers Provides a record/playback tool for authoring tests without learning a test scripting language Open source • Consists of a set of software tools that facilitate testing • Can be coded in many programming languages • Primarily developed in JavaScript • Browser and platform independent

19. Selenium suite of tools Selenium IDE Selenium Remote Control (RC) Selenium suite Selenium WebDriver Selenium Grid

20. Selenium suite of tools Selenium Integrated development environment (IDE) • Developed by Shinya Kasatani • Firefox or Chrome extension that can automate the browser functionality • Records user interactions on the browser and exports them as a reusable script • Selenese commands can be used to modify the test script generated after recording • Selenium IDE deploys on Windows, Linux, and MacOS platforms Selenium suite

21. Selenium suite of tools Selenium Integrated development environment (IDE) • Selenium IDE ceased to exist in August 2017 • A robust version of IDE was released in 2018 by Applitools • The new IDE deploys a Selenium Side Runner that allows all IDE tests to run on any browser, in parallel, and on a grid without needing to write any code. • Selenium IDE is integrated with other suite components to provide a robust interface for application testing Selenium suite

29. Selenium suite of tools Selenium Remote Control (RC) • Paul Hammantdeveloped Selenium RC • Selenium RC is a server written in Java • RC makes provision for writing application tests in various programming languages like Java, C#, Perl, PHP, Python etc. • The RC server accepts commands from the user program and passes them to the browser as Selenium-Core JavaScript commands • The browser behaves accordingly Selenium suite

30. Selenium suite of tools Selenium Remote Control (RC) Selenium suite RC Server test.js Web browser injected with Selenium core Consider a JavaScript program test.js used by google.com

31. Selenium suite of tools Selenium Remote Control (RC) Selenium suite RC Server test.js Web browser injected with Selenium core • However, it cannot access elements of other domains like yahoo.com

32. Selenium suite of tools Selenium Remote Control (RC) Selenium suite RC Server test.js Web browser injected with Selenium core • This is called Same Origin Policy and Selenium RC was introduced to address this limitation. The server acts as a client configured HTTP proxy and "tricks" the browser into believing that Selenium Core and the web application being tested come from the same origin

33. Selenium suite of tools Selenium WebDriver • Simon Stewart developed WebDriver in 2006 • The first cross-platform testing framework • Programming interface to create and run test cases • Makes provision to act on web elements • Does not require a core engine like RC and interacts natively with the browser applications • Supports Java, C#, PHP, Python, Perl, Ruby, etc. • Supports frameworks like TestNG, JUnit, NUnit Selenium suite

34. Selenium suite of tools Selenium WebDriver Selenium suite Selenium WebDriver does not require an additional RC. It directly interacts with browser and controls its working

35. Selenium suite of tools Selenium Grid • Developed by Patrick Lightbody • The main objective of Grid is to minimize test execution time • Grid was designed to distribute commands to different machines simultaneously • Selenium Grid allows the parallel execution of tests on different browsers and different operating systems • Grid is exceptionally flexible and is integrated with other suite components for simultaneous execution Selenium suite

36. Selenium suite of tools Selenium Grid Selenium suite The Grid consists of a hub connected to several nodes. It receives the test to be executed along with information about the operating system and browser to be run on

37. Selenium suite of tools Selenium Grid Selenium suite The hub picks a node that conforms to the requirements (browser and platform) and passes the test to that node

38. Advantages of Selenium testing

39. Advantages of Selenium testing Supports various browsers and operating systems Speed and Accuracy Ease of implementation Open source Supports wide spectrum of programming languages Reusability and Add-ons

40. Limitations of Selenium testing

41. Limitations of Selenium testing Limited support for image testing Tests web applications only No reliable tech support No built in reporting facility Limited test management May require knowledge of programming languages
