Introduction to selenium

1. Selenium
Test

2. Manual Testing and its Challenges
Testing Web apps manually involves:
•Entering all the data manually
•Validating the form
•Taking all the screenshots for valid or
Invalid scenarios
•Creating pass/fail reports

5. How Automation Testing Beats Manual
Test Scripts Scripts Executed Test Reports

6. Advantages of Automation Testing
Faster Execution More Accurate Execution Less Investment
Frequent Execution
Support Regression Testing Supports Lights out Execution

7. Selenium as an Automation
Testing Tool
Supports different PL :
Supports different OS:
Supports different Browsers:

8. Selenium Advantages
• Open Source Software
• Supports Multiple programming language
• Supports Multiple OS
• Supports Mutli Browser Testing
• Supports parallel test execution
• Supports different framework
like:TestNG,Cucumber,etc.

9. Selenium Disadvantages
• Supports only Web Applications
• Difficult to Setup and use
• No reporting facility
• Limited support for image based testing
• No PDF automation
• Only user Communities available

10. Selenium Vs. Other Automation Tools

11. Selenium Evolution

12. Selenium IDE
• Selenium IDE is a Firefox and Chrome plug-in
which is used to create and execute test cases.
• Its records and plays back the interactions which
the user had with the web browser
• Using IDE, you can export the programming code
in different languages :java,Ruby,Python,etc.

13. IDE Features
• Create and edit test cases
• Create and execute test suites
• Debug and enhance test cases
• Test cases can be exported to different PL
• Enables learning of Selenium’s script syntax

14. IDE Drawbacks
• Supports only Mozilla Firefox and Chrome
browser
• Not suitable for automating Dynamic web
applications
• No support for programming logic
• Data Driven Testing is not possible
• No centralized maintenance of objects or
elements

15. Selenium RC
• RC is used to write web application tests in different PL
• It interacts with browser with the help of Selenium RC
Server
• Selenium RC Server communicates using simple HTTP
GET/POST requests
• Major drawback of the RC Server is that every
communication with the Server is time consuming and
hence RC is slow

16. Selenium Webdriver
• Selenium Webdriver is a programming interface
to create and execute test cases
• Test cases are created and executed using
Elements/object locators/ Webdriver methods
• Selenium Webdriver has programming interface
but not the IDE
• Fast as it interacts directly with browser.RC needs
to interact with the server

17. Selenium Webdriver
• Each browser has its own driver on which the application
runs.Selenium Webdriver makes direct calls to the browser
• For testing on a local machine,you need to use
Webdriver.But for testing on a remote machine,you need
selenium RC server
• While testing a remote machine,commands from
Webdriver go to Selenium RC Server which is then
interpreted on remote machine to automate the browser

18. Selenium Webdriver Drawbacks
• Detailed test reports can not be generated
• No centralized maintenance of
objects/elements

19. Selenium GRID
• Selenium GRID is used to run multiple test scripts at
the same time on multiple machines
• Grid supports RC test as well as Webdriver test
• Parallel execution is achieved with the help of Hub-
Node architecture
• Hub can control different test scripts on various
browser,OS and PL in various nodes

20. Selenium GRID

21. Waterfall Model

22. V Model

23. Defect Life Cycle

24. MTM Defect Logging
