This document discusses web application testing using Selenium. It covers the basics of automation testing, why it is important, and how to design an automation framework with Selenium. The key points covered include setting up the architecture with different layers, writing basic Selenium tests, building out the framework, best practices like continuous integration, and tips for scaling tests. The goal is to help attendees understand how to create a robust and maintainable Selenium test automation framework.

Web Application Testing with Selenium
- 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?
- 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
- 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
- 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
