Transcript

1. WEB APPLICATION TESTING WITH SELENIUM Sargis Sargsyan QA Automation Engineer
2. Who This Presentation Is For •  Developers or QA (Students who will become developer or QA) •  Know the basics of an automation tool •  In this presentation Selenium •  Want to create a real automation framework WELCOME TO THE AUTOMATION FACTORY OF NAIRIT
3. What this Presentation Covers •  Introduction •  Basic of automation •  Why and how we’ll do it •  Designing The Architecture •  How to design an automation framework •  Creating Basic Selenium Test •  The best place to start •  Building Out The Framework •  Refactoring •  Designing framework for more tests •  Best Practices and Tips •  Continuous Integration, Scaling out, Agile, etc. WE WILL AUTOMATE YOU!
4. INTRODUCTION •  Basic of automation •  Why and how we’ll do it
5. Type Of Automated Testing
6. UNIT TEST IS TESTING SMALL UNIT OF CODE IN ISOLATION Unit Testing
7. INTEGRATION TESTING TEST UNITS TOGETHER, BUT STILL FOCUSES ON THE CODE Integration Testing
8. BATS TEST THE SYSTEM FROM THE PERSPECTIVE OF THE USER Blackbox Automated Testing (BAT)
9. THE TEST PYRAMID IS A CONCEPT DEVELOPED BY MIKE COHN Pyramid of the Testing
10. Selenium is a web application testing framework that allows you to write tests in many programming languages like: •  Java •  C# •  Groovy •  Perl •  PHP •  Python •  Ruby What is Selenium? Selenium deploys on •  Windows, •  Linux, •  MAC OS. It is an open-source project!
11. 2004 – Jason Huggins creates a JavaScript based tool for automatic testing called Selenium (now it is known as Selenium Core). Later Selenium Remote Control (aka Selenium RC) was developed to address the “same host origin” browser policy and allow many language bindings to control the browser at a distance 2006 – Simon Stewart started working on another web testing tool called WebDriver 2009 – Selenium RC and WebDriver are merged into a one project called Selenium-WebDriver (aka Selenium 2.0) 2013 – The first working draft of WebDriver API W3C Specification is released A Bit of History
12. Terminology •  Selenium Core •  Selenium RC •  Selenium-WebDriver •  Selenium Server •  Selenium IDE •  Selenium-Grid
13. CAN’T WE JUST USE OUR UNIT & INTEGRATION TESTS AND RUN OTHERS MANUALLY? Why Do It?
14. IT WORKED YESTERDAY! Regression
15. THIS TEST EXPLAINS EXACTLY WHAT I WANT AND WHAT YOU AGREED TO Absolute Requirements
16. BATS TEST MUCH MORE PRODUCTION CODE WITH FEWER LINES OF CODE Leverage
17. OUR APPROACH
18. TESTS DON’T DIRECTLY WORK AGAINST THE WEB APP Separate Automation Framework Web App Framework Tests
19. I TOTALLY UNDERSTAND WHAT THESE TEST ARE DOING. Simple Test
20. I AM AN AUTOMATED TEST, I’LL BE DRIVING TODAY. YOU CAN ALL ME ARMAN Test Drive Creation of Framework
21. DESIGNING THE ARCHITECTURE
22. EACH LAYER ONLY INTERACTS WITH THE LAYER IMMEDIATELY BELOW IT Architecture
23. THE FRAMEWORK ITSELF SHOULD BE DIVIDED BY LAYERS OF FUNCTIONALITY Thinking About Layers
24. Thinking about Ease of Use
25. THE CHOICE MAKES A HUGE DIFFERENCE Which is Easier? OR
26. PREPARE TO BECOME AN AUTOMATION NINJA! Let’s Start the Coding
27. COMMON FAILURE POINTS
28. NEVER RECORD A TEST CASE! Recorded Brittle Test
29. NEVER RECORD A TEST CASE! Not Building a Framework
30. WHAT THE HECK AM I LOOKING AT? Writing Test Like a Code
31. NOT EVERYTHING CAN BE AUTOMATED! Automating Hard Things
32. •  Test fail because •  The condition testes was not met •  An Assertion in the test failed •  Test error because •  Something other than what was being testes failed •  The framework threw an exception IT IS IMPORTANT TO MAKE A DISTINCTION BETWEEN ERRORS & FAILURES Error vs Failures
33. •  Have a plan and stick to it •  Run test as part of build •  Run test locally •  Report results •  Break builds MAKE SURE AUTOMATED TEST ARE TAKEN SERIOUSLY Continuous Integration
34. MAKE SURE AUTOMATED TEST ARE TAKEN SERIOUSLY Our Continuous Integration
35. HOW YOU WILL FEEL WHEN YOUR AUTOMATED TESTS ALL PASS The End!
36. THANK YOU! Time for Questions
